+ Node to draw simple geometry from code, ala OpenGL 1.x
</brief_description>
<description>
</description>
+ ImmediateGeometry is a node used for displaying simple geometry created from code, very similar to how glBegin() and glEnd() worked in old versions of OpenGL (1.x).
+ Simply call [method begin()], and add vertices. For custom vertex colors, uvs, normal, etc. call one of the set_ functions below before adding each vertex. When done, call [method end]
+ Calls to begin/end are accumulative and all geometry is added together. To clear all the geometry, call [method clear].
+ If a material override is set, and this material contains a texture, it's possible to override the texture used in this material for every begin/end set of calls.

- /* USER-SELECTABLE CONFIGURATION MACROS */
- /* */
- /* This file contains the default configuration macro definitions for */
- /* a standard build of the FreeType library. There are three ways to */
- /* use this file to build project-specific versions of the library: */
- /* */
- /* - You can modify this file by hand, but this is not recommended in */
- /* cases where you would like to build several versions of the */
- /* library from a single source directory. */
- /* */
- /* - You can put a copy of this file in your build directory, more */
- /* precisely in `$BUILD/freetype/config/ftoption.h', where `$BUILD' */
- /* is the name of a directory that is included _before_ the FreeType */
- /* include path during compilation. */
- /* */
- /* The default FreeType Makefiles and Jamfiles use the build */
- /* directory `builds/<system>' by default, but you can easily change */
- /* that for your own projects. */
- /* */
- /* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
- /* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
- /* locate this file during the build. For example, */
- /* */
- /* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
- /* #include <freetype/config/ftheader.h> */
- /* */
- /* will use `$BUILD/myftoptions.h' instead of this file for macro */
- /* definitions. */
- /* */
- /* Note also that you can similarly pre-define the macro */
- /* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
- /* that are statically linked to the library at compile time. By */
- /* default, this file is <freetype/config/ftmodule.h>. */
- /* */
- /* We highly recommend using the third method whenever possible. */

- *
- * @enum:
- * FT_LOAD_XXX
- *
- * @description:
- * A list of bit-field constants used with @FT_Load_Glyph to indicate
- * what kind of operations to perform during glyph loading.
- *
- * @values:
- * FT_LOAD_DEFAULT ::
- * Corresponding to~0, this value is used as the default glyph load
- * operation. In this case, the following happens:
- *
- * 1. FreeType looks for a bitmap for the glyph corresponding to the
- * face's current size. If one is found, the function returns.
- * The bitmap data can be accessed from the glyph slot (see note
- * below).
- *
- * 2. If no embedded bitmap is searched or found, FreeType looks for a
- * scalable outline. If one is found, it is loaded from the font
- * file, scaled to device pixels, then `hinted' to the pixel grid
- * in order to optimize it. The outline data can be accessed from
- * the glyph slot (see note below).
- *
- * Note that by default, the glyph loader doesn't render outlines into
- * bitmaps. The following flags are used to modify this default
- * behaviour to more specific and useful cases.
- *
- * FT_LOAD_NO_SCALE ::
- * Don't scale the loaded outline glyph but keep it in font units.
- *
- * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
- * unsets @FT_LOAD_RENDER.
- *
- * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
- * FT_LOAD_NO_SCALE usually yields meaningless outlines because the
- * subglyphs must be scaled and positioned with hinting instructions.
- * This can be solved by loading the font without FT_LOAD_NO_SCALE and
- * setting the character size to `font->units_per_EM'.
- *
- * FT_LOAD_NO_HINTING ::
- * Disable hinting. This generally generates `blurrier' bitmap glyphs
- * when the glyph are rendered in any of the anti-aliased modes. See
- * also the note below.
- *
- * This flag is implied by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_RENDER ::
- * Call @FT_Render_Glyph after the glyph is loaded. By default, the
- * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
- * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
- *
- * This flag is unset by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_NO_BITMAP ::
- * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
- * flag.
- *
- * @FT_LOAD_NO_SCALE always sets this flag.
- *
- * FT_LOAD_VERTICAL_LAYOUT ::
- * Load the glyph for vertical text layout. In particular, the
- * `advance' value in the @FT_GlyphSlotRec structure is set to the
- * `vertAdvance' value of the `metrics' field.
- *
- * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
- * this flag currently. Reason is that in this case vertical metrics
- * get synthesized, and those values are not always consistent across
- * various font formats.
- *
- * FT_LOAD_FORCE_AUTOHINT ::
- * Indicates that the auto-hinter is preferred over the font's native
- * hinter. See also the note below.
- *
- * FT_LOAD_CROP_BITMAP ::
- * Indicates that the font driver should crop the loaded bitmap glyph
- * (i.e., remove all space around its black bits). Not all drivers
- * implement this.
- *
- * FT_LOAD_PEDANTIC ::
- * Indicates that the font driver should perform pedantic verifications
- * during glyph loading. This is mostly used to detect broken glyphs
- * in fonts. By default, FreeType tries to handle broken fonts also.
- *
- * In particular, errors from the TrueType bytecode engine are not
- * passed to the application if this flag is not set; this might
- * result in partially hinted or distorted glyphs in case a glyph's
- * bytecode is buggy.
- *
- * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
- * Ignored. Deprecated.
- *
- * FT_LOAD_NO_RECURSE ::
- * This flag is only used internally. It merely indicates that the
- * font driver should not load composite glyphs recursively. Instead,
- * it should set the `num_subglyph' and `subglyphs' values of the
- * glyph slot accordingly, and set `glyph->format' to
- * @FT_GLYPH_FORMAT_COMPOSITE.
- *
- * The description of sub-glyphs is not available to client
- * applications for now.
- *
- * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
- *
- * FT_LOAD_IGNORE_TRANSFORM ::
- * Indicates that the transform matrix set by @FT_Set_Transform should
- * be ignored.
- *
- * FT_LOAD_MONOCHROME ::
- * This flag is used with @FT_LOAD_RENDER to indicate that you want to
- * render an outline glyph to a 1-bit monochrome bitmap glyph, with
- * 8~pixels packed into each byte of the bitmap data.
- *
- * Note that this has no effect on the hinting algorithm used. You
- * should rather use @FT_LOAD_TARGET_MONO so that the
- * monochrome-optimized hinting algorithm is used.
- *
- * FT_LOAD_LINEAR_DESIGN ::
- * Indicates that the `linearHoriAdvance' and `linearVertAdvance'
- * fields of @FT_GlyphSlotRec should be kept in font units. See
- * @FT_GlyphSlotRec for details.
- *
- * FT_LOAD_NO_AUTOHINT ::
- * Disable auto-hinter. See also the note below.
- *
- * FT_LOAD_COLOR ::
- * This flag is used to request loading of color embedded-bitmap
- * images. The resulting color bitmaps, if available, will have the
- * @FT_PIXEL_MODE_BGRA format. When the flag is not used and color
- * bitmaps are found, they will be converted to 256-level gray
- * bitmaps transparently. Those bitmaps will be in the
- * @FT_PIXEL_MODE_GRAY format.
- *
- * @note:
- * By default, hinting is enabled and the font's native hinter (see
- * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
- * disable hinting by setting @FT_LOAD_NO_HINTING or change the
- * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
- * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
- * used at all.
- *
- * See the description of @FT_FACE_FLAG_TRICKY for a special exception
- * (affecting only a handful of Asian fonts).
- *
- * Besides deciding which hinter to use, you can also decide which
- * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
- *
- * Note that the auto-hinter needs a valid Unicode cmap (either a native
- * one or synthesized by FreeType) for producing correct results. If a
- * font provides an incorrect mapping (for example, assigning the
- * character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
- * mathematical integral sign), the auto-hinter might produce useless
- * results.

- * `load_flags' when calling @FT_Load_Glyph.
- *
- * Note that font's native hinters may ignore the hinting algorithm you
- * have specified (e.g., the TrueType bytecode interpreter). You can set
- * @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.
- *
- * Also note that @FT_LOAD_TARGET_LIGHT is an exception, in that it
- * always implies @FT_LOAD_FORCE_AUTOHINT.
- *
- * @values:
- * FT_LOAD_TARGET_NORMAL ::
- * This corresponds to the default hinting algorithm, optimized for
- * standard gray-level rendering. For monochrome output, use
- * @FT_LOAD_TARGET_MONO instead.
- *
- * FT_LOAD_TARGET_LIGHT ::
- * A lighter hinting algorithm for non-monochrome modes. Many
- * generated glyphs are more fuzzy but better resemble its original
- * shape. A bit like rendering on Mac OS~X.
- *
- * As a special exception, this target implies @FT_LOAD_FORCE_AUTOHINT.
- *
- * FT_LOAD_TARGET_MONO ::
- * Strong hinting algorithm that should only be used for monochrome
- * output. The result is probably unpleasant if the glyph is rendered
- * in non-monochrome modes.
- *
- * FT_LOAD_TARGET_LCD ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
- * decimated LCD displays.
- *
- * FT_LOAD_TARGET_LCD_V ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
- * decimated LCD displays.
- *
- * @note:
- * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
- * `load_flags'. They can't be ORed.
- *
- * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
- * corresponding mode (i.e., the mode which matches the used algorithm
- * best). An exeption is FT_LOAD_TARGET_MONO since it implies
- * @FT_LOAD_MONOCHROME.
- *
- * You can use a hinting algorithm that doesn't correspond to the same
- * rendering mode. As an example, it is possible to use the `light'
- * hinting algorithm and have the results rendered in horizontal LCD
- * pixel mode, with code like
- *
- * {
- * FT_Load_Glyph( face, glyph_index,
- * load_flags | FT_LOAD_TARGET_LIGHT );
- *
- * FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );

- /* introduce Ideographic Variation Sequences (IVS), consisting of a */

- /* (format~14). It is an odd subtable because it is not a mapping of */
- /* input code points to glyphs, but contains lists of all variants */
- /* supported by the font. */
- /* */
- /* A variant may be either `default' or `non-default'. A default */

- *
- * @property:
- * glyph-to-script-map
- *
- * @description:
- * *Experimental* *only*
- *
- * The auto-hinter provides various script modules to hint glyphs.
- * Examples of supported scripts are Latin or CJK. Before a glyph is
- * auto-hinted, the Unicode character map of the font gets examined, and
- * the script is then determined based on Unicode character ranges, see
- * below.
- *
- * OpenType fonts, however, often provide much more glyphs than
- * character codes (small caps, superscripts, ligatures, swashes, etc.),
- * to be controlled by so-called `features'. Handling OpenType features
- * can be quite complicated and thus needs a separate library on top of
- * FreeType.
- *
- * The mapping between glyph indices and scripts (in the auto-hinter
- * sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
- * array with `num_glyphs' elements, as found in the font's @FT_Face
- * structure. The `glyph-to-script-map' property returns a pointer to
- * this array which can be modified as needed. Note that the
- * modification should happen before the first glyph gets processed by
- * the auto-hinter so that the global analysis of the font shapes
- * actually uses the modified mapping.
- *
- * The following example code demonstrates how to access it (omitting
- * the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_Prop_GlyphToScriptMap prop;
- *
- *
- * FT_Init_FreeType( &library );
- * FT_New_Face( library, "foo.ttf", 0, &face );
- *
- * prop.face = face;
- *
- * FT_Property_Get( library, "autofitter",
- * "glyph-to-script-map", &prop );
- *
- * // adjust `prop.map' as needed right here
- *
- * FT_Load_Glyph( face, ..., FT_LOAD_FORCE_AUTOHINT );

- * <Section>

- *
- * <Title>
- * Cache Sub-System
- *
- * <Abstract>
- * How to cache face, size, and glyph data with FreeType~2.
- *
- * <Description>
- * This section describes the FreeType~2 cache sub-system, which is used
- * to limit the number of concurrently opened @FT_Face and @FT_Size
- * objects, as well as caching information like character maps and glyph
- * images while limiting their maximum memory usage.
- *
- * Note that all types and functions begin with the `FTC_' prefix.
- *
- * The cache is highly portable and thus doesn't know anything about the
- * fonts installed on your system, or how to access them. This implies
- * the following scheme:
- *
- * First, available or installed font faces are uniquely identified by
- * @FTC_FaceID values, provided to the cache by the client. Note that
- * the cache only stores and compares these values, and doesn't try to
- * interpret them in any way.
- *
- * Second, the cache calls, only when needed, a client-provided function
- * to convert an @FTC_FaceID into a new @FT_Face object. The latter is
- * then completely managed by the cache, including its termination
- * through @FT_Done_Face. To monitor termination of face objects, the
- * finalizer callback in the `generic' field of the @FT_Face object can
- * be used, which might also be used to store the @FTC_FaceID of the
- * face.
- *
- * Clients are free to map face IDs to anything else. The most simple
- * usage is to associate them to a (pathname,face_index) pair that is
- * used to call @FT_New_Face. However, more complex schemes are also
- * possible.
- *
- * Note that for the cache to work correctly, the face ID values must be
- * *persistent*, which means that the contents they point to should not
- * change at runtime, or that their value should not become invalid.
- *
- * If this is unavoidable (e.g., when a font is uninstalled at runtime),
- * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
- * the cache get rid of any references to the old @FTC_FaceID it may
- * keep internally. Failure to do so will lead to incorrect behaviour
- * or even crashes.
- *
- * To use the cache, start with calling @FTC_Manager_New to create a new
- * @FTC_Manager object, which models a single cache instance. You can
- * then look up @FT_Face and @FT_Size objects with
- * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
- *
- * If you want to use the charmap caching, call @FTC_CMapCache_New, then
- * later use @FTC_CMapCache_Lookup to perform the equivalent of
- * @FT_Get_Char_Index, only much faster.
- *
- * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
- * later use @FTC_ImageCache_Lookup to retrieve the corresponding
- * @FT_Glyph objects from the cache.
- *
- * If you need lots of small bitmaps, it is much more memory efficient
- * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This
- * returns @FTC_SBitRec structures, which are used to store small
- * bitmaps directly. (A small bitmap is one whose metrics and
- * dimensions all fit into 8-bit integers).
- *
- * We hope to also provide a kerning cache in the near future.

- * LCD Filtering
- *
- * @abstract:
- * Reduce color fringes of LCD-optimized bitmaps.
- *
- * @description:
- * The @FT_Library_SetLcdFilter API can be used to specify a low-pass
- * filter which is then applied to LCD-optimized bitmaps generated
- * through @FT_Render_Glyph. This is useful to reduce color fringes
- * which would occur with unfiltered rendering.
- *
- * Note that no filter is active by default, and that this function is
- * *not* implemented in default builds of the library. You need to
- * #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
- * in order to activate it.
- *
- * FreeType generates alpha coverage maps, which are linear by nature.
- * For instance, the value 0x80 in bitmap representation means that
- * (within numerical precision) 0x80/0xff fraction of that pixel is
- * covered by the glyph's outline. The blending function for placing
- * text over a background is
- *
- * {
- * dst = alpha * src + (1 - alpha) * dst ,
- * }
- *
- * which is known as OVER. However, when calculating the output of the
- * OVER operator, the source colors should first be transformed to a
- * linear color space, then alpha blended in that space, and transformed
- * back to the output color space.
- *
- * When linear light blending is used, the default FIR5 filtering
- * weights (as given by FT_LCD_FILTER_DEFAULT) are no longer optimal, as
- * they have been designed for black on white rendering while lacking
- * gamma correction. To preserve color neutrality, weights for a FIR5
- * filter should be chosen according to two free parameters `a' and `c',
- * and the FIR weights should be
- *
- * {
- * [a - c, a + c, 2 * a, a + c, a - c] .
- * }
- *
- * This formula generates equal weights for all the color primaries
- * across the filter kernel, which makes it colorless. One suggested
- * set of weights is
- *
- * {
- * [0x10, 0x50, 0x60, 0x50, 0x10] ,
- * }
- *
- * where `a' has value 0x30 and `b' value 0x20. The weights in filter
- * may have a sum larger than 0x100, which increases coloration slightly
- * but also improves contrast.

- * @property:
- * interpreter-version
- *
- * @description:
- * Currently, two versions are available which represent the bytecode
- * interpreter with and without subpixel hinting support,
- * respectively. The default is subpixel support if
- * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel
- * support otherwise (since it isn't available then).
- *
- * If subpixel hinting is on, many TrueType bytecode instructions
- * behave differently compared to B/W or grayscale rendering. The
- * main idea is to render at a much increased horizontal resolution,
- * then sampling down the created output to subpixel precision.
- * However, many older fonts are not suited to this and must be
- * specially taken care of by applying (hardcoded) font-specific
- * tweaks.
- *
- * Details on subpixel hinting and some of the necessary tweaks can be
- * found in Greg Hitchcock's whitepaper at
- * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
- *
- * The following example code demonstrates how to activate subpixel
- * hinting (omitting the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_38;
- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "truetype",
- * "interpreter-version",
- * &interpreter_version );
- * }
- *
- * @note:
- * This property can be used with @FT_Property_Get also.

- * @enum:
- * TT_INTERPRETER_VERSION_XXX
- *
- * @description:
- * A list of constants used for the @interpreter-version property to
- * select the hinting engine for Truetype fonts.
- *
- * The numeric value in the constant names represents the version
- * number as returned by the `GETINFO' bytecode instruction.
- *
- * @values:
- * TT_INTERPRETER_VERSION_35 ::
- * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
- * Windows~98; only grayscale and B/W rasterizing is supported.
- *
- * TT_INTERPRETER_VERSION_38 ::
- * Version~38 corresponds to MS rasterizer v.1.9; it is roughly
- * equivalent to the hinting provided by DirectWrite ClearType (as
- * can be found, for example, in the Internet Explorer~9 running on
- * Windows~7).
- *
- * @note:
- * This property controls the behaviour of the bytecode interpreter
- * and thus how outlines get hinted. It does *not* control how glyph
- * get rasterized! In particular, it does not control subpixel color
- * filtering.
- *
- * If FreeType has not been compiled with configuration option
- * FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
- * `FT_Err_Unimplemented_Feature' error.

- * @values:
- * FT_WinFNT_ID_DEFAULT ::
- * This is used for font enumeration and font creation as a
- * `don't care' value. Valid font files don't contain this value.
- * When querying for information about the character set of the font

- * FT_WinFNT_ID_MAC ::
- * Mac Roman encoding.
- *
- * FT_WinFNT_ID_OEM ::
- * From Michael Pöttgen <michael@poettgen.de>:
- *
- * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
- * is used for the charset of vector fonts, like `modern.fon',
- * `roman.fon', and `script.fon' on Windows.
- *
- * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
- * specifies a character set that is operating-system dependent.
- *
- * The `IFIMETRICS' documentation from the `Windows Driver
- * Development Kit' says: This font supports an OEM-specific
- * character set. The OEM character set is system dependent.
- *
- * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
- * second default codepage that most international versions of
- * Windows have. It is one of the OEM codepages from
- *
- * http://www.microsoft.com/globaldev/reference/cphome.mspx,
- *
- * and is used for the `DOS boxes', to support legacy applications.
- * A German Windows version for example usually uses ANSI codepage
- * 1252 and OEM codepage 850.
- *
- * FT_WinFNT_ID_CP874 ::
- * A superset of Thai TIS 620 and ISO 8859-11.
- *
- * FT_WinFNT_ID_CP932 ::
- * A superset of Japanese Shift-JIS (with minor deviations).
- *
- * FT_WinFNT_ID_CP936 ::
- * A superset of simplified Chinese GB 2312-1980 (with different

- /* A small technical note regarding automatic hinting in order to */

- /* */
- /* An automatic hinter might compute two kinds of data for a given face: */
- /* */
- /* - global hints: Usually some metrics that describe global properties */
- /* of the face. It is computed by scanning more or less */
- /* aggressively the glyphs in the face, and thus can be */
- /* very slow to compute (even if the size of global */
- /* hints is really small). */
- /* */
- /* - glyph hints: These describe some important features of the glyph */
- /* outline, as well as how to align them. They are */
- /* generally much faster to compute than global hints. */
- /* */
- /* The current FreeType auto-hinter does a pretty good job while */
- /* performing fast computations for both global and glyph hints. */
- /* However, we might be interested in introducing more complex and */
- /* powerful algorithms in the future, like the one described in the John */
- /* D. Hobby paper, which unfortunately requires a lot more horsepower. */
- /* */
- /* Because a sufficiently sophisticated font management system would */
- /* typically implement an LRU cache of opened face objects to reduce */
- /* memory usage, it is a good idea to be able to avoid recomputing */
- /* global hints every time the same face is re-opened. */
- /* */
- /* We thus provide the ability to cache global hints outside of the face */
- /* object, in order to speed up font re-opening time. Of course, this */
- /* feature is purely optional, so most client programs won't even notice */
- /* it. */
- /* */
- /* I initially thought that it would be a good idea to cache the glyph */
- /* hints too. However, my general idea now is that if you really need */
- /* to cache these too, you are simply in need of a new font format, */
- /* where all this information could be stored within the font file and */
- /* decoded on the fly. */

- * This rewinds the recorder and prepare it for new input.
- *
- * - For each hint found in the glyph charstring, call the corresponding
- * method (`stems', `hintmask', `counters'). Note that these
- * functions do not return an error code.
- *
- * - Close the recording session by calling the `close' method. It
- * returns an error code if the hints were invalid or something
- * strange happened (e.g., memory shortage).
- *
- * The hints accumulated in the object can later be used by the
- * Postscript hinter.

- * @function:
- * FT_Get_PS_Font_Value
- *
- * @description:
- * Retrieve the value for the supplied key from a PostScript font.
- *
- * @input:
- * face ::
- * PostScript face handle.
- *
- * key ::
- * An enumeration value representing the dictionary key to retrieve.
- *
- * idx ::
- * For array values, this specifies the index to be returned.
- *
- * value ::
- * A pointer to memory into which to write the value.
- *
- * valen_len ::
- * The size, in bytes, of the memory supplied for the value.
- *
- * @output:
- * value ::
- * The value matching the above key, if it exists.
- *
- * @return:
- * The amount of memory (in bytes) required to hold the requested
- * value (if it exists, -1 otherwise).
- *
- * @note:
- * The values returned are not pointers into the internal structures of
- * the face, but are `fresh' copies, so that the memory containing them
- * belongs to the calling application. This also enforces the
- * `read-only' nature of these values, i.e., this function cannot be
- * used to manipulate the face.
- *
- * `value' is a void pointer because the values returned can be of
- * various types.
- *
- * If either `value' is NULL or `value_len' is too small, just the
- * required memory size for the requested entry is returned.
- *
- * The `idx' parameter is used, not only to retrieve elements of, for
- * example, the FontMatrix or FontBBox, but also to retrieve name keys
- * from the CharStrings dictionary, and the charstrings themselves. It
- * is ignored for atomic values.
- *
- * PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To
- * get the value as in the font stream, you need to divide by
- * 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
- *
- * IMPORTANT: Only key/value pairs read by the FreeType interpreter can
- * be retrieved. So, for example, PostScript procedures such as NP,
- * ND, and RD are not available. Arbitrary keys are, obviously, not be
- * available either.
- *
- * If the font's format is not PostScript-based, this function returns
- * the `FT_Err_Invalid_Argument' error code.

- /* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */

- * The following explanations are mostly taken from the article

- * Real-Time Grid Fitting of Typographic Outlines

- *
- *
- * Segments
- *
- * `af_{cjk,latin,...}_hints_compute_segments' are the functions to
- * find segments in an outline. A segment is a series of consecutive
- * points that are approximately aligned along a coordinate axis. The
- * analysis to do so is specific to a script.
- *
- * A segment must have at least two points, except in the case of
- * `fake' segments that are generated to hint metrics appropriately,
- * and which consist of a single point.
- *
- *
- * Edges
- *
- * As soon as segments are defined, the auto-hinter groups them into
- * edges. An edge corresponds to a single position on the main
- * dimension that collects one or more segments (allowing for a small
- * threshold).
- *
- * The auto-hinter first tries to grid fit edges, then to align
- * segments on the edges unless it detects that they form a serif.
- *
- * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
- * edges; they are specific to a script.

- *
- *
- * Stems
- *
- * Segments need to be `linked' to other ones in order to detect stems.
- * A stem is made of two segments that face each other in opposite
- * directions and that are sufficiently close to each other. Using
- * vocabulary from the TrueType specification, stem segments form a
- * `black distance'.
- *
- * In the above ASCII drawing, the horizontal segments are BC, DE, and
- * FG; the vertical segments are AB, CD, EF, and GH.
- *
- * Each segment has at most one `best' candidate to form a black
- * distance, or no candidate at all. Notice that two distinct segments
- * can have the same candidate, which frequently means a serif.
- *
- * A stem is recognized by the following condition:
- *
- * best segment_1 = segment_2 && best segment_2 = segment_1
- *
- * The best candidate is stored in field `link' in structure
- * `AF_Segment'.
- *
- * Stems are detected by `af_{cjk,latin,...}_hint_edges'.
- *
- * In the above ASCII drawing, the best candidate for both AB and CD is
- * GH, while the best candidate for GH is AB. Similarly, the best
- * candidate for EF and GH is AB, while the best candidate for AB is
- * GH.
- *
- *
- * Serifs
- *
- * On the opposite, a serif has
- *
- * best segment_1 = segment_2 && best segment_2 != segment_1
- *
- * where segment_1 corresponds to the serif segment (CD and EF in the
- * above ASCII drawing).
- *
- * The best candidate is stored in field `serif' in structure
- * `AF_Segment' (and `link' is set to NULL).
- *
- * Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
- *
- *
- * Touched points
- *
- * A point is called `touched' if it has been processed somehow by the
- * auto-hinter. It basically means that it shouldn't be moved again
- * (or moved only under certain constraints to preserve the already
- * applied processing).
- *
- *
- * Flat and round segments
- *
- * Segments are `round' or `flat', depending on the series of points
- * that define them. A segment is round if the next and previous point
- * of an extremum (which can be either a single point or sequence of
- * points) are both conic or cubic control points. Otherwise, a
- * segment with an extremum is flat.
- *
- *
- * Strong Points
- *
- * Experience has shown that points which are not part of an edge need
- * to be interpolated linearly between their two closest edges, even if
- * these are not part of the contour of those particular points.
- * Typical candidates for this are
- *
- * - angle points (i.e., points where the `in' and `out' direction
- * differ greatly)
- *
- * - inflection points (i.e., where the `in' and `out' angles are the
- * same, but the curvature changes sign)
- *
- * `af_glyph_hints_align_strong_points' is the function which takes
- * care of such situations; it is equivalent to the TrueType `IP'
- * hinting instruction.
- *
- *
- * Weak Points
- *
- * Other points in the outline must be interpolated using the
- * coordinates of their previous and next unfitted contour neighbours.
- * These are called `weak points' and are touched by the function
- * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
- * hinting instruction. Typical candidates are control points and
- * points on the contour without a major direction.
- *
- * The major effect is to reduce possible distortion caused by
- * alignment of edges and strong points, thus weak points are processed
- * after strong points.

- Notes
-
- Mac suitcase files can (and often do!) contain multiple fonts. To
- support this I use the face_index argument of FT_(Open|New)_Face()
- functions, and pretend the suitcase file is a collection.
-
- Warning: fbit and NFNT bitmap resources are not supported yet. In old
- sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
- resources instead of the `bdat' table in the sfnt resource. Therefore,
- face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
- resource is unavailable at present.
-
- The Mac FOND support works roughly like this:
-
- - Check whether the offered stream points to a Mac suitcase file. This
- is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
- stream that gets passed to our init_face() routine is a stdio stream,
- which isn't usable for us, since the FOND resources live in the
- resource fork. So we just grab the stream->pathname field.
-
- - Read the FOND resource into memory, then check whether there is a
- TrueType font and/or(!) a Type 1 font available.
-
- - If there is a Type 1 font available (as a separate `LWFN' file), read
- its data into memory, massage it slightly so it becomes PFB data, wrap
- it into a memory stream, load the Type 1 driver and delegate the rest
- of the work to it by calling FT_Open_Face(). (XXX TODO: after this
- has been done, the kerning data from the FOND resource should be
- appended to the face: On the Mac there are usually no AFM files
- available. However, this is tricky since we need to map Mac char
- codes to ps glyph names to glyph ID's...)
-
- - If there is a TrueType font (an `sfnt' resource), read it into memory,
- wrap it into a memory stream, load the TrueType driver and delegate
- the rest of the work to it, by calling FT_Open_Face().
-
- - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
- itself, even though it doesn't contains `POST' resources. To handle
- this special case without opening the file an extra time, we just
- ignore errors from the `LWFN' and fallback to the `sfnt' if both are
- available.

- /*
- *
- * FTC_GCache is an _abstract_ cache object optimized to store glyph
- * data. It works as follows:
- *
- * - It manages FTC_GNode objects. Each one of them can hold one or more
- * glyph `items'. Item types are not specified in the FTC_GCache but
- * in classes that extend it.
- *
- * - Glyph attributes, like face ID, character size, render mode, etc.,
- * can be grouped into abstract `glyph families'. This avoids storing
- * the attributes within the FTC_GCache, since it is likely that many
- * FTC_GNodes will belong to the same family in typical uses.
- *
- * - Each FTC_GNode is thus an FTC_Node with two additional fields:
- *
- * * gindex: A glyph index, or the first index in a glyph range.
- * * family: A pointer to a glyph `family'.
- *
- * - Family types are not fully specific in the FTC_Family type, but
- * by classes that extend it.
- *
- * Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
- * They share an FTC_Family sub-class called FTC_BasicFamily which is
- * used to store the following data: face ID, pixel/point sizes, load
- * flags. For more details see the file `src/cache/ftcbasic.c'.
- *
- * Client applications can extend FTC_GNode with their own FTC_GNode
- * and FTC_Family sub-classes to implement more complex caches (e.g.,
- * handling automatic synthesis, like obliquing & emboldening, colored
- * glyphs, etc.).
- *
- * See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
- * `ftcsbits.h', which both extend FTC_GCache with additional
- * optimizations.
- *
- * A typical FTC_GCache implementation must provide at least the
- * following:
- *
- * - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
- * my_node_new (must call FTC_GNode_Init)
- * my_node_free (must call FTC_GNode_Done)
- * my_node_compare (must call FTC_GNode_Compare)
- * my_node_remove_faceid (must call ftc_gnode_unselect in case
- * of match)
- *
- * - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
- * my_family_compare
- * my_family_init
- * my_family_reset (optional)
- * my_family_done
- *
- * - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
- * data.
- *
- * - Constant structures for a FTC_GNodeClass.
- *
- * - MyCacheNew() can be implemented easily as a call to the convenience
- * function FTC_GCache_New.
- *
- * - MyCacheLookup with a call to FTC_GCache_Lookup. This function will
- * automatically:
- *
- * - Search for the corresponding family in the cache, or create
- * a new one if necessary. Put it in FTC_GQUERY(myquery).family
- *
- * - Call FTC_Cache_Lookup.
- *
- * If it returns NULL, you should create a new node, then call
- * ftc_cache_add as usual.

- * Here, we want to load a small bitmap on-demand; we thus

- * a non-zero error code only when we are out of memory (OOM).
- *
- * The correct thing to do is to use @FTC_CACHE_TRYLOOP and
- * @FTC_CACHE_TRYLOOP_END in order to implement a retry loop
- * that is capable of flushing the cache incrementally when
- * an OOM errors occur.
- *
- * However, we need to `lock' the node before this operation to
- * prevent it from being flushed within the loop.
- *
- * When we exit the loop, we unlock the node, then check the `error'
- * variable. If it is non-zero, this means that the cache was
- * completely flushed and that no usable memory was found to load
- * the bitmap.
- *
- * We then prefer to return a value of 0 (i.e., NO MATCH). This
- * ensures that the caller will try to allocate a new node.
- * This operation consequently _fail_ and the lookup function
- * returns the appropriate OOM error code.
- *
- * Note that `buffer == NULL && width == 255' is a hack used to
- * tag `unavailable' bitmaps in the array. We should never try
- * to load these.

- * A poor-man error facility.
- *
- * This code being written in vanilla C, doesn't have the luxury of a
- * language-supported exception mechanism such as the one available in
- * Java. Instead, we are stuck with using error codes that must be
- * carefully managed and preserved. However, it is convenient for us to
- * model our error mechanism on a Java-like exception mechanism.
- * When we assign an error code we are thus `throwing' an error.
- *
- * The perservation of an error code is done by coding convention.
- * Upon a function call if the error code is anything other than
- * `FT_Err_Ok', which is guaranteed to be zero, we
- * will return without altering that error. This will allow the
- * error to propogate and be handled at the appropriate location in
- * the code.
- *
- * This allows a style of code where the error code is initialized
- * up front and a block of calls are made with the error code only
- * being checked after the block. If a new error occurs, the original
- * error will be preserved and a functional no-op should result in any
- * subsequent function that has an initial error code not equal to
- * `FT_Err_Ok'.
- *
- * Errors are encoded by calling the `FT_THROW' macro. For example,
- *
- * {
- * FT_Error e;
- *
- *
- * ...
- * e = FT_THROW( Out_Of_Memory );
- * }

-gxvalid: TrueType GX validator
-==============================
-
-
-1. What is this
----------------
-
- `gxvalid' is a module to validate TrueType GX tables: a collection of
- additional tables in TrueType font which are used by `QuickDraw GX
- Text', Apple Advanced Typography (AAT). In addition, gxvalid can
- validates `kern' tables which have been extended for AAT. Like the
- otvalid module, gxvalid uses Freetype 2's validator framework
- (ftvalid).
-
- You can link gxvalid with your program; before running your own layout
- engine, gxvalid validates a font file. As the result, you can remove
- error-checking code from the layout engine. It is also possible to
- use gxvalid as a stand-alone font validator; the `ftvalid' test
- program included in the ft2demo bundle calls gxvalid internally.
- A stand-alone font validator may be useful for font developers.
-
- This documents documents the following issues.
-
- - supported TrueType GX tables
- - fundamental validation limitations
- - permissive error handling of broken GX tables
- - `kern' table issue.
-
-
-2. Supported tables
--------------------
-
- The following GX tables are currently supported.
-
- bsln
- feat
- just
- kern(*)
- lcar
- mort
- morx
- opbd
- prop
- trak
-
- The following GX tables are currently unsupported.
-
- cvar
- fdsc
- fmtx
- fvar
- gvar
- Zapf
-
- The following GX tables won't be supported.
-
- acnt(**)
- hsty(***)
-
- The following undocumented tables in TrueType fonts designed for Apple
- platform aren't handled either.
-
- addg
- CVTM
- TPNM
- umif
-
-
- *) The `kern' validator handles both the classic and the new kern
- formats; the former is supported on both Microsoft and Apple
- platforms, while the latter is supported on Apple platforms.
-
- **) `acnt' tables are not supported by currently available Apple font
- tools.
-
- ***) There is one more Apple extension, `hsty', but it is for
- Newton-OS, not GX (Newton-OS is a platform by Apple, but it can
- use sfnt- housed bitmap fonts only). Therefore, it should be
- excluded from `Apple platform' in the context of TrueType.
- gxvalid ignores it as Apple font tools do so.
-
-
- We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS
- 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition,
- we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh
- fonts (designed for Windows and MacOS dual platforms). The number of
- fonts including TrueType GX tables are as follows.
-
- bsln: 76
- feat: 191
- just: 84
- kern: 59
- lcar: 4
- mort: 326
- morx: 19
- opbd: 4
- prop: 114
- trak: 16
-
- Dynalab and Ricoh fonts don't have GX tables except of `feat' and
- `mort'.
-
-
-3. Fundamental validation limitations
--------------------------------------
-
- TrueType GX provides layout information to libraries for font
- rasterizers and text layout. gxvalid can check whether the layout
- data in a font is conformant to the TrueType GX format specified by
- Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses
- the stored information.
-
- 3-1. Validation of State Machine activity
- -----------------------------------------
-
- QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
- features, and TrueType GX stores the state transition diagram of
- this `State Machine' in a `StateTable' data structure. While the
- State Machine receives a series of glyph IDs, the State Machine
- starts with `start of text' state, walks around various states and
- generates various layout information to the renderer, and finally
- reaches the `end of text' state.
-
- gxvalid can check essential errors like:
-
- - possibility of state transitions to undefined states
- - existence of glyph IDs that the State Machine doesn't know how
- to handle
- - the State Machine cannot compute the layout information from
- given diagram
-
- These errors can be checked within finite steps, and without the
- State Machine itself, because these are `expression' errors of state
- transition diagram.
-
- There is no limitation about how long the State Machine walks
- around, so validation of the algorithm in the state transition
- diagram requires infinite steps, even if we had a State Machine in
- gxvalid. Therefore, the following errors and problems cannot be
- checked.
-
- - existence of states which the State Machine never transits to
- - the possibility that the State Machine never reaches `end of
- text'
- - the possibility of stack underflow/overflow in the State Machine
- (in ligature and contextual glyph substitutions, the State
- Machine can store 16 glyphs onto its stack)
-
- In addition, gxvalid doesn't check `temporary glyph IDs' used in the
- chained State Machines (in `mort' and `morx' tables). If a layout
- feature is implemented by a single State Machine, a glyph ID
- converted by the State Machine is passed to the glyph renderer, thus
- it should not point to an undefined glyph ID. But if a layout
- feature is implemented by chained State Machines, a component State
- Machine (if it is not the final one) is permitted to generate
- undefined glyph IDs for temporary use, because it is handled by next
- component State Machine and not by the glyph renderer. To validate
- such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
- which can occur in the output of the previous State Machine and
- search them in the `ClassTable' structure of the current State
- Machine. It is too complex to list all possible glyph IDs from the
- StateTable, especially from a ligature substitution table.
-
- 3-2. Validation of relationship between multiple layout features
- ----------------------------------------------------------------
-
- gxvalid does not validate the relationship between multiple layout
- features at all.
-
- If multiple layout features are defined in TrueType GX tables,
- possible interactions, overrides, and conflicts between layout
- features are implicitly given in the font too. For example, there
- are several predefined spacing control features:
-
- - Text Spacing (Proportional/Monospace/Half-width/Normal)
- - Number Spacing (Monospaced-numbers/Proportional-numbers)
- - Kana Spacing (Full-width/Proportional)
- - Ideographic Spacing (Full-width/Proportional)
- - CJK Roman Spacing (Half-width/Proportional/Default-roman
- /Full-width-roman/Proportional)
-
- If all layout features are independently managed, we can activate
- inconsistent typographic rules like `Text Spacing=Monospace' and
- `Ideographic Spacing=Proportional' at the same time.
-
- The combinations of layout features is managed by a 32bit integer
- (one bit each for selector setting), so we can define relationships
- between up to 32 features, theoretically. But if one feature
- setting affects another feature setting, we need typographic
- priority rules to validate the relationship. Unfortunately, the
- TrueType GX format specification does not give such information even
- for predefined features.
-
-
-4. Permissive error handling of broken GX tables
-------------------------------------------------
-
- When Apple's font rendering system finds an inconsistency, like a
- specification violation or an unspecified value in a TrueType GX
- table, it does not always return error. In most cases, the rendering
- engine silently ignores such wrong values or even whole tables. In
- fact, MacOS is shipped with fonts including broken GX/AAT tables, but
- no harmful effects due to `officially broken' fonts are observed by
- end-users.
-
- gxvalid is designed to continue the validation process as long as
- possible. When gxvalid find wrong values, gxvalid warns it at least,
- and takes a fallback procedure if possible. The fallback procedure
- depends on the debug level.
-
- We used the following three tools to investigate Apple's error handling.
-
- - FontValidator (for MacOS 8.5 - 9.2) resource fork font
- - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt
- - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt
-
- However, all tests were done on a PowerPC based Macintosh; at present,
- we have not checked those tools on a m68k-based Macintosh.
-
- In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS
- 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts
- are distributed officially, but many broken GX/AAT tables were found
- by Apple's font tools. In the following, we list typical violation of
- the GX specification, in fonts officially distributed with those Apple
- systems.
-
- 4-1. broken BinSrchHeader (19/183)
- ----------------------------------
-
- `BinSrchHeader' is a header of a data array for m68k platforms to
- access memory efficiently. Although there are only two independent
- parameters for real (`unitSize' and `nUnits'), BinSrchHeader has
- three additional parameters which can be calculated from `unitSize'
- and `nUnits', for fast setup. Apple font tools ignore them
- silently, so gxvalid warns if it finds and inconsistency, and always
- continues validation. The additional parameters are ignored
- regardless of the consistency.
-
- 19 fonts include such inconsistencies; all breaks are in the
- BinSrchHeader structure of the `kern' table.
-
- 4-2. too-short LookupTable (5/183)
- ----------------------------------
-
- LookupTable format 0 is a simple array to get a value from a given
- GID (glyph ID); the index of this array is a GID too. Therefore,
- the length of the array is expected to be same as the maximum GID
- value defined in the `maxp' table, but there are some fonts whose
- LookupTable format 0 is too short to cover all GIDs. FontValidator
- ignores this error silently, ftxvalidator and ftxdumperfuser both
- warn and continue. Similar problems are found in format 3 subtables
- of `kern'. gxvalid warns always and abort if the validation level
- is set to FT_VALIDATE_PARANOID.
-
- 5 fonts include too-short kern format 0 subtables.
- 1 font includes too-short kern format 3 subtable.
-
- 4-3. broken LookupTable format 2 (1/183)
- ----------------------------------------
-
- LookupTable format 2, subformat 4 covers the GID space by a
- collection of segments which are specified by `firstGlyph' and
- `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in
- reverse order, so the segment specification is broken. Apple font
- tools ignore this error silently; a broken segment is ignored as if
- it did not exist. gxvalid warns and normalize the segment at
- FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or
- abort at FT_VALIDATE_PARANOID.
-
- 1 font includes broken LookupTable format 2, in the `just' table.
-
- *) It seems that all fonts manufactured by ITC for AppleWorks have
- this error.
-
- 4-4. bad bracketing in glyph property (14/183)
- ----------------------------------------------
-
- GX/AAT defines a `bracketing' property of the glyphs in the `prop'
- table, to control layout features of strings enclosed inside and
- outside of brackets. Some fonts give inappropriate bracket
- properties to glyphs. Apple font tools warn about this error;
- gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
-
- 14 fonts include wrong bracket properties.
-
-
- 4-5. invalid feature number (117/183)
- -------------------------------------
-
- The GX/AAT extension can include 255 different layout features, but
- popular layout features are predefined (see
- http://developer.apple.com/fonts/Registry/index.html). Some fonts
- include feature numbers which are incompatible with the predefined
- feature registry.
-
- In our survey, there are 140 fonts including `feat' table.
-
- a) 67 fonts use a feature number which should not be used.
- b) 117 fonts set the wrong feature range (nSetting). This is mostly
- found in the `mort' and `morx' tables.
-
- Apple font tools give no warning, although they cannot recognize
- what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but
- continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns
- and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID,
- gxvalid warns and aborts in both cases (a, b).
-
- 4-6. invalid prop version (10/183)
- ----------------------------------
-
- As most TrueType GX tables, the `prop' table must start with a 32bit
- version identifier: 0x00010000, 0x00020000 or 0x00030000. But some
- fonts store nonsense binary data instead. When Apple font tools
- find them, they abort the processing immediately, and the data which
- follows is unhandled. gxvalid does the same.
-
- 10 fonts include broken `prop' version.
-
- All of these fonts are classic TrueType fonts for the Japanese
- script, manufactured by Apple.
-
- 4-7. unknown resource name (2/183)
- ------------------------------------
-
- NOTE: THIS IS NOT A TRUETYPE GX ERROR.
-
- If a TrueType font is stored in the resource fork or in dfont
- format, the data must be tagged as `sfnt' in the resource fork index
- to invoke TrueType font handler for the data. But the TrueType font
- data in `Keyboard.dfont' is tagged as `kbd', and that in
- `LastResort.dfont' is tagged as `lst'. Apple font tools can detect
- that the data is in TrueType format and successfully validate them.
- Maybe this is possible because they are known to be dfont. The
- current implementation of the resource fork driver of FreeType
- cannot do that, thus gxvalid cannot validate them.
-
- 2 fonts use an unknown tag for the TrueType font resource.
-
-5. `kern' table issues
-----------------------
-
- In common terminology of TrueType, `kern' is classified as a basic and
- platform-independent table. But there are Apple extensions of `kern',
- and there is an extension which requires a GX state machine for
- contextual kerning. Therefore, gxvalid includes a special validator
- for `kern' tables. Unfortunately, there is no exact algorithm to
- check Apple's extension, so gxvalid includes a heuristic algorithm to
- find the proper validation routines for all possible data formats,
- including the data format for Microsoft. By calling
- classic_kern_validate() instead of gxv_validate(), you can specify the
- `kern' format explicitly. However, current FreeType2 uses Microsoft
- `kern' format only, others are ignored (and should be handled in a
- library one level higher than FreeType).
-
- 5-1. History
- ------------
-
- The original 16bit version of `kern' was designed by Apple in the
- pre-GX era, and it was also approved by Microsoft. Afterwards,
- Apple designed a new 32bit version of the `kern' table. According
- to the documentation, the difference between the 16bit and 32bit
- version is only the size of variables in the `kern' header. In the
- following, we call the original 16bit version as `classic', and
- 32bit version as `new'.
-
- 5-2. Versions and dialects which should be differentiated
- ---------------------------------------------------------
-
- The `kern' table consists of a table header and several subtables.
- The version number which identifies a `classic' or a `new' version
- is explicitly written in the table header, but there are
- undocumented differences between Microsoft's and Apple's formats.
- It is called a `dialect' in the following. There are three cases
- which should be handled: the new Apple-dialect, the classic
- Apple-dialect, and the classic Microsoft-dialect. An analysis of
- the formats and the auto detection algorithm of gxvalid is described
- in the following.
-
- 5-2-1. Version detection: classic and new kern
- ----------------------------------------------
-
- According to Apple TrueType specification, there are only two
- differences between the classic and the new:
-
- - The `kern' table header starts with the version number.
- The classic version starts with 0x0000 (16bit),
- the new version starts with 0x00010000 (32bit).
-
- - In the `kern' table header, the number of subtables follows
- the version number.
- In the classic version, it is stored as a 16bit value.
- In the new version, it is stored as a 32bit value.
-
- From Apple font tool's output (DumpKERN is also tested in addition
- to the three Apple font tools in above), there is another
- undocumented difference. In the new version, the subtable header
- includes a 16bit variable named `tupleIndex' which does not exist
- in the classic version.
-
- The new version can store all subtable formats (0, 1, 2, and 3),
- but the Apple TrueType specification does not mention the subtable
- formats available in the classic version.
-
- 5-2-2. Available subtable formats in classic version
- ----------------------------------------------------
-
- Although the Apple TrueType specification recommends to use the
- classic version in the case if the font is designed for both the
- Apple and Microsoft platforms, it does not document the available
- subtable formats in the classic version.
-
- According to the Microsoft TrueType specification, the subtable
- format assured for Windows and OS/2 support is only subtable
- format 0. The Microsoft TrueType specification also describes
- subtable format 2, but does not mention which platforms support
- it. Aubtable formats 1, 3, and higher are documented as reserved
- for future use. Therefore, the classic version can store subtable
- formats 0 and 2, at least. `ttfdump.exe', a font tool provided by
- Microsoft, ignores the subtable format written in the subtable
- header, and parses the table as if all subtables are in format 0.
-
- `kern' subtable format 1 uses a StateTable, so it cannot be
- utilized without a GX State Machine. Therefore, it is reasonable
- to assume that format 1 (and 3) were introduced after Apple had
- introduced GX and moved to the new 32bit version.
-
- 5-2-3. Apple and Microsoft dialects
- -----------------------------------
-
- The `kern' subtable has a 16bit `coverage' field to describe
- kerning attributes, but bit interpretations by Apple and Microsoft
- are different: For example, Apple uses bits 0-7 to identify the
- subtable, while Microsoft uses bits 8-15.
-
- In addition, due to the output of DumpKERN and FontValidator,
- Apple's bit interpretations of coverage in classic and new version
- are incompatible also. In summary, there are three dialects:
- classic Apple dialect, classic Microsoft dialect, and new Apple
- dialect. The classic Microsoft dialect and the new Apple dialect
- are documented by each vendors' TrueType font specification, but
- the documentation for classic Apple dialect is not available.
-
- For example, in the new Apple dialect, bit 15 is documented as
- `set to 1 if the kerning is vertical'. On the other hand, in
- classic Microsoft dialect, bit 1 is documented as `set to 1 if the
- kerning is horizontal'. From the outputs of DumpKERN and
- FontValidator, classic Apple dialect recognizes 15 as `set to 1
- when the kerning is horizontal'. From the results of similar
- experiments, classic Apple dialect seems to be the Endian reverse
- of the classic Microsoft dialect.
-
- As a conclusion it must be noted that no font tool can identify
- classic Apple dialect or classic Microsoft dialect automatically.
-
- 5-2-4. gxvalid auto dialect detection algorithm
- -----------------------------------------------
-
- The first 16 bits of the `kern' table are enough to identify the
- version:
-
- - if the first 16 bits are 0x0000, the `kern' table is in
- classic Apple dialect or classic Microsoft dialect
- - if the first 16 bits are 0x0001, and next 16 bits are 0x0000,
- the kern table is in new Apple dialect.
-
- If the `kern' table is a classic one, the 16bit `coverage' field
- is checked next. Firstly, the coverage bits are decoded for the
- classic Apple dialect using the following bit masks (this is based
- on DumpKERN output):
-
- 0x8000: 1=horizontal, 0=vertical
- 0x4000: not used
- 0x2000: 1=cross-stream, 0=normal
- 0x1FF0: reserved
- 0x000F: subtable format
-
- If any of reserved bits are set or the subtable bits is
- interpreted as format 1 or 3, we take it as `impossible in classic
- Apple dialect' and retry, using the classic Microsoft dialect.
-
- The most popular coverage in new Apple-dialect: 0x8000,
- The most popular coverage in classic Apple-dialect: 0x0000,
- The most popular coverage in classic Microsoft dialect: 0x0001.
-
- 5-3. Tested fonts
- -----------------
-
- We checked 59 fonts bundled with MacOS and 38 fonts bundled with
- Windows, where all font include a `kern' table.
-
- - fonts bundled with MacOS
- * new Apple dialect
- format 0: 18
- format 2: 1
- format 3: 1
- * classic Apple dialect
- format 0: 14
- * classic Microsoft dialect
- format 0: 15
-
- - fonts bundled with Windows
- * classic Microsoft dialect
- format 0: 38
-
- It looks strange that classic Microsoft-dialect fonts are bundled to
- MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.

- ACKNOWLEDGEMENT
- ---------------
-
- Some parts of gxvalid are derived from both the `gxlayout' module and
- the `otvalid' module. Development of gxlayout was supported by the
- Information-technology Promotion Agency(IPA), Japan.
-
- The detailed analysis of undefined glyph ID utilization in `mort' and
- `morx' tables is provided by George Williams.

- /* A simple technical note on how the raster works */
- /* ----------------------------------------------- */
- /* */
- /* Converting an outline into a bitmap is achieved in several steps: */
- /* */
- /* 1 - Decomposing the outline into successive `profiles'. Each */
- /* profile is simply an array of scanline intersections on a given */
- /* dimension. A profile's main attributes are */
- /* */
- /* o its scanline position boundaries, i.e. `Ymin' and `Ymax' */
- /* */
- /* o an array of intersection coordinates for each scanline */
- /* between `Ymin' and `Ymax' */
- /* */
- /* o a direction, indicating whether it was built going `up' or */
- /* `down', as this is very important for filling rules */
- /* */
- /* o its drop-out mode */
- /* */
- /* 2 - Sweeping the target map's scanlines in order to compute segment */
- /* `spans' which are then filled. Additionally, this pass */
- /* performs drop-out control. */
- /* */
- /* The outline data is parsed during step 1 only. The profiles are */
- /* built from the bottom of the render pool, used as a stack. The */
- /* following graphics shows the profile list under construction: */
- /* */
- /* __________________________________________________________ _ _ */
- /* | | | | | */
- /* | profile | coordinates for | profile | coordinates for |--> */
- /* | 1 | profile 1 | 2 | profile 2 |--> */
- /* |_________|_________________|_________|_________________|__ _ _ */
- /* */
- /* ^ ^ */
- /* | | */
- /* start of render pool top */
- /* */
- /* The top of the profile stack is kept in the `top' variable. */
- /* */
- /* As you can see, a profile record is pushed on top of the render */
- /* pool, which is then followed by its coordinates/intersections. If */
- /* a change of direction is detected in the outline, a new profile is */
- /* generated until the end of the outline. */
- /* */
- /* Note that when all profiles have been generated, the function */
- /* Finalize_Profile_Table() is used to record, for each profile, its */
- /* bottom-most scanline as well as the scanline above its upmost */
- /* boundary. These positions are called `y-turns' because they (sort */
- /* of) correspond to local extrema. They are stored in a sorted list */
- /* built from the top of the render pool as a downwards stack: */
- /* */
- /* _ _ _______________________________________ */
- /* | | */
- /* <--| sorted list of | */
- /* <--| extrema scanlines | */
- /* _ _ __________________|____________________| */
- /* */
- /* ^ ^ */
- /* | | */
- /* maxBuff sizeBuff = end of pool */
- /* */
- /* This list is later used during the sweep phase in order to */
- /* optimize performance (see technical note on the sweep below). */
- /* */
- /* Of course, the raster detects whether the two stacks collide and */
- /* handles the situation properly. */

- /***** says about this format, but here is my conclusion. *****/
- /***** *****/
- /***** The purpose of this format is to easily map UTF-16 text to *****/
- /***** glyph indices. Basically, the `char_code' must be in one of *****/
- /***** the following formats: *****/
- /***** *****/
- /***** - A 16-bit value that isn't part of the Unicode Surrogates *****/
- /***** Area (i.e. U+D800-U+DFFF). *****/
- /***** *****/
- /***** - A 32-bit value, made of two surrogate values, i.e.. if *****/
- /***** `char_code = (char_hi << 16) | char_lo', then both *****/
- /***** `char_hi' and `char_lo' must be in the Surrogates Area. *****/
- /***** Area. *****/
- /***** *****/
- /***** The `is32' table embedded in the charmap indicates whether a *****/
- /***** given 16-bit value is in the surrogates area or not. *****/
- /***** *****/
- /***** So, for any given `char_code', we can assert the following: *****/
- /***** *****/
- /***** If `char_hi == 0' then we must have `is32[char_lo] == 0'. *****/
- /***** *****/
- /***** If `char_hi != 0' then we must have both *****/
- /***** `is32[char_hi] != 0' and `is32[char_lo] != 0'. *****/

- /* _not_ try to read the Type 1 token stream with a state machine (i.e. */
- /* a Postscript-like interpreter) but rather to perform simple pattern */
- /* matching. */
- /* */
- /* Indeed, nearly all data definitions follow a simple pattern like */

- /* ... /Field <data> ... */
- /* */
- /* where <data> can be a number, a boolean, a string, or an array of */
- /* numbers. There are a few exceptions, namely the encoding, font name, */
- /* charstrings, and subrs; they are handled with a special pattern */
- /* matching routine. */
- /* */
- /* All other common cases are handled very simply. The matching rules */
- /* are defined in the file `t1tokens.h' through the use of several */
- /* macros calls PARSE_XXX. This file is included twice here; the first */

- /* */
- /* The function `parse_dict' simply scans *linearly* a given dictionary */
- /* (either the top-level or private one) and calls the appropriate */
- /* callback when it encounters an immediate keyword. */
- /* */
- /* This is by far the fastest way one can find to parse and read all */
- /* data. */
- /* */
- /* This led to tremendous code size reduction. Note that later, the */
- /* glyph loader will also be _greatly_ simplified, and the automatic */

+ *
+ * @enum:
+ * FT_LOAD_XXX
+ *
+ * @description:
+ * A list of bit field constants used with @FT_Load_Glyph to indicate
+ * what kind of operations to perform during glyph loading.
+ *
+ * @values:
+ * FT_LOAD_DEFAULT ::
+ * Corresponding to~0, this value is used as the default glyph load
+ * operation. In this case, the following happens:
+ *
+ * 1. FreeType looks for a bitmap for the glyph corresponding to the
+ * face's current size. If one is found, the function returns.
+ * The bitmap data can be accessed from the glyph slot (see note
+ * below).
+ *
+ * 2. If no embedded bitmap is searched or found, FreeType looks for a
+ * scalable outline. If one is found, it is loaded from the font
+ * file, scaled to device pixels, then `hinted' to the pixel grid
+ * in order to optimize it. The outline data can be accessed from
+ * the glyph slot (see note below).
+ *
+ * Note that by default, the glyph loader doesn't render outlines into
+ * bitmaps. The following flags are used to modify this default
+ * behaviour to more specific and useful cases.
+ *
+ * FT_LOAD_NO_SCALE ::
+ * Don't scale the loaded outline glyph but keep it in font units.
+ *
+ * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
+ * unsets @FT_LOAD_RENDER.
+ *
+ * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
+ * FT_LOAD_NO_SCALE usually yields meaningless outlines because the
+ * subglyphs must be scaled and positioned with hinting instructions.
+ * This can be solved by loading the font without FT_LOAD_NO_SCALE and
+ * setting the character size to `font->units_per_EM'.
+ *
+ * FT_LOAD_NO_HINTING ::
+ * Disable hinting. This generally generates `blurrier' bitmap glyphs
+ * when the glyph are rendered in any of the anti-aliased modes. See
+ * also the note below.
+ *
+ * This flag is implied by @FT_LOAD_NO_SCALE.
+ *
+ * FT_LOAD_RENDER ::
+ * Call @FT_Render_Glyph after the glyph is loaded. By default, the
+ * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
+ * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
+ *
+ * This flag is unset by @FT_LOAD_NO_SCALE.
+ *
+ * FT_LOAD_NO_BITMAP ::
+ * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
+ * flag.
+ *
+ * @FT_LOAD_NO_SCALE always sets this flag.
+ *
+ * FT_LOAD_VERTICAL_LAYOUT ::
+ * Load the glyph for vertical text layout. In particular, the
+ * `advance' value in the @FT_GlyphSlotRec structure is set to the
+ * `vertAdvance' value of the `metrics' field.
+ *
+ * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
+ * this flag currently. Reason is that in this case vertical metrics
+ * get synthesized, and those values are not always consistent across
+ * various font formats.
+ *
+ * FT_LOAD_FORCE_AUTOHINT ::
+ * Indicates that the auto-hinter is preferred over the font's native
+ * hinter. See also the note below.
+ *
+ * FT_LOAD_PEDANTIC ::
+ * Indicates that the font driver should perform pedantic verifications
+ * during glyph loading. This is mostly used to detect broken glyphs
+ * in fonts. By default, FreeType tries to handle broken fonts also.
+ *
+ * In particular, errors from the TrueType bytecode engine are not
+ * passed to the application if this flag is not set; this might
+ * result in partially hinted or distorted glyphs in case a glyph's
+ * bytecode is buggy.
+ *
+ * FT_LOAD_NO_RECURSE ::
+ * Indicate that the font driver should not load composite glyphs
+ * recursively. Instead, it should set the `num_subglyph' and
+ * `subglyphs' values of the glyph slot accordingly, and set
+ * `glyph->format' to @FT_GLYPH_FORMAT_COMPOSITE. The description of
+ * subglyphs can then be accessed with @FT_Get_SubGlyph_Info.
+ *
+ * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
+ *
+ * FT_LOAD_IGNORE_TRANSFORM ::
+ * Indicates that the transform matrix set by @FT_Set_Transform should
+ * be ignored.
+ *
+ * FT_LOAD_MONOCHROME ::
+ * This flag is used with @FT_LOAD_RENDER to indicate that you want to
+ * render an outline glyph to a 1-bit monochrome bitmap glyph, with
+ * 8~pixels packed into each byte of the bitmap data.
+ *
+ * Note that this has no effect on the hinting algorithm used. You
+ * should rather use @FT_LOAD_TARGET_MONO so that the
+ * monochrome-optimized hinting algorithm is used.
+ *
+ * FT_LOAD_LINEAR_DESIGN ::
+ * Indicates that the `linearHoriAdvance' and `linearVertAdvance'
+ * fields of @FT_GlyphSlotRec should be kept in font units. See
+ * @FT_GlyphSlotRec for details.
+ *
+ * FT_LOAD_NO_AUTOHINT ::
+ * Disable auto-hinter. See also the note below.
+ *
+ * FT_LOAD_COLOR ::
+ * This flag is used to request loading of color embedded-bitmap
+ * images. The resulting color bitmaps, if available, will have the
+ * @FT_PIXEL_MODE_BGRA format. When the flag is not used and color
+ * bitmaps are found, they will be converted to 256-level gray
+ * bitmaps transparently. Those bitmaps will be in the
+ * @FT_PIXEL_MODE_GRAY format.
+ *
+ * FT_LOAD_COMPUTE_METRICS ::
+ * This flag sets computing glyph metrics without the use of bundled
+ * metrics tables (for example, the `hdmx' table in TrueType fonts).
+ * Well-behaving fonts have optimized bundled metrics and these should
+ * be used. This flag is mainly used by font validating or font
+ * editing applications, which need to ignore, verify, or edit those
+ * tables.
+ *
+ * Currently, this flag is only implemented for TrueType fonts.
+ *
+ * FT_LOAD_CROP_BITMAP ::
+ * Ignored. Deprecated.
+ *
+ * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
+ * Ignored. Deprecated.
+ *
+ * @note:
+ * By default, hinting is enabled and the font's native hinter (see
+ * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
+ * disable hinting by setting @FT_LOAD_NO_HINTING or change the
+ * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
+ * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
+ * used at all.
+ *
+ * See the description of @FT_FACE_FLAG_TRICKY for a special exception
+ * (affecting only a handful of Asian fonts).
+ *
+ * Besides deciding which hinter to use, you can also decide which
+ * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
+ *
+ * Note that the auto-hinter needs a valid Unicode cmap (either a native
+ * one or synthesized by FreeType) for producing correct results. If a
+ * font provides an incorrect mapping (for example, assigning the
+ * character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
+ * mathematical integral sign), the auto-hinter might produce useless
+ * results.

+ *
+ * @description:
+ * A list of values that are used to select a specific hinting algorithm
+ * to use by the hinter. You should OR one of these values to your
+ * `load_flags' when calling @FT_Load_Glyph.
+ *
+ * Note that font's native hinters may ignore the hinting algorithm you
+ * have specified (e.g., the TrueType bytecode interpreter). You can set
+ * @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.
+ *
+ * @values:
+ * FT_LOAD_TARGET_NORMAL ::
+ * This corresponds to the default hinting algorithm, optimized for
+ * standard gray-level rendering. For monochrome output, use
+ * @FT_LOAD_TARGET_MONO instead.
+ *
+ * FT_LOAD_TARGET_LIGHT ::
+ * A lighter hinting algorithm for gray-level modes. Many generated
+ * glyphs are fuzzier but better resemble their original shape. This
+ * is achieved by snapping glyphs to the pixel grid only vertically
+ * (Y-axis), as is done by Microsoft's ClearType and Adobe's
+ * proprietary font renderer. This preserves inter-glyph spacing in
+ * horizontal text. The snapping is done either by the native font
+ * driver if the driver itself and the font support it or by the
+ * auto-hinter.
+ *
+ * FT_LOAD_TARGET_MONO ::
+ * Strong hinting algorithm that should only be used for monochrome
+ * output. The result is probably unpleasant if the glyph is rendered
+ * in non-monochrome modes.
+ *
+ * FT_LOAD_TARGET_LCD ::
+ * A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
+ * decimated LCD displays.
+ *
+ * FT_LOAD_TARGET_LCD_V ::
+ * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
+ * decimated LCD displays.
+ *
+ * @note:
+ * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
+ * `load_flags'. They can't be ORed.
+ *
+ * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
+ * corresponding mode (i.e., the mode that matches the used algorithm
+ * best). An exception is FT_LOAD_TARGET_MONO since it implies
+ * @FT_LOAD_MONOCHROME.
+ *
+ * You can use a hinting algorithm that doesn't correspond to the same

+ * @description:
+ * *Experimental* *only*
+ *
+ * The auto-hinter provides various script modules to hint glyphs.
+ * Examples of supported scripts are Latin or CJK. Before a glyph is
+ * auto-hinted, the Unicode character map of the font gets examined, and
+ * the script is then determined based on Unicode character ranges, see
+ * below.
+ *
+ * OpenType fonts, however, often provide much more glyphs than
+ * character codes (small caps, superscripts, ligatures, swashes, etc.),
+ * to be controlled by so-called `features'. Handling OpenType features
+ * can be quite complicated and thus needs a separate library on top of
+ * FreeType.
+ *
+ * The mapping between glyph indices and scripts (in the auto-hinter
+ * sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
+ * array with `num_glyphs' elements, as found in the font's @FT_Face
+ * structure. The `glyph-to-script-map' property returns a pointer to
+ * this array, which can be modified as needed. Note that the
+ * modification should happen before the first glyph gets processed by
+ * the auto-hinter so that the global analysis of the font shapes
+ * actually uses the modified mapping.
+ *
+ * The following example code demonstrates how to access it (omitting
+ * the error handling).

+ * Stem darkening emboldens glyphs at smaller sizes to make them more
+ * readable on common low-DPI screens when using linear alpha blending
+ * and gamma correction, see @FT_Render_Glyph. When not using linear
+ * alpha blending and gamma correction, glyphs will appear heavy and
+ * fuzzy!
+ *
+ * Gamma correction essentially lightens fonts since shades of grey are
+ * shifted to higher pixel values (=~higher brightness) to match the
+ * original intention to the reality of our screens. The side-effect is
+ * that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
+ * rendering library implement a counter-measure: stem darkening at
+ * smaller sizes where shades of gray dominate. By emboldening a glyph
+ * slightly in relation to its pixel size, individual pixels get higher
+ * coverage of filled-in outlines and are therefore `blacker'. This
+ * counteracts the `thinning out' of glyphs, making text remain readable
+ * at smaller sizes. All glyphs that pass through the auto-hinter will
+ * be emboldened unless this property is set to TRUE.
+ *
+ * See the description of the CFF driver for algorithmic details. Total
+ * consistency with the CFF driver is currently not achieved because the
+ * emboldening method differs and glyphs must be scaled down on the
+ * Y-axis to keep outline points inside their precomputed blue zones.

+ *
+ * <Title>
+ * Cache Sub-System
+ *
+ * <Abstract>
+ * How to cache face, size, and glyph data with FreeType~2.
+ *
+ * <Description>
+ * This section describes the FreeType~2 cache sub-system, which is used
+ * to limit the number of concurrently opened @FT_Face and @FT_Size
+ * objects, as well as caching information like character maps and glyph
+ * images while limiting their maximum memory usage.
+ *
+ * Note that all types and functions begin with the `FTC_' prefix.
+ *
+ * The cache is highly portable and thus doesn't know anything about the
+ * fonts installed on your system, or how to access them. This implies
+ * the following scheme:
+ *
+ * First, available or installed font faces are uniquely identified by
+ * @FTC_FaceID values, provided to the cache by the client. Note that
+ * the cache only stores and compares these values, and doesn't try to
+ * interpret them in any way.
+ *
+ * Second, the cache calls, only when needed, a client-provided function
+ * to convert an @FTC_FaceID into a new @FT_Face object. The latter is
+ * then completely managed by the cache, including its termination
+ * through @FT_Done_Face. To monitor termination of face objects, the
+ * finalizer callback in the `generic' field of the @FT_Face object can
+ * be used, which might also be used to store the @FTC_FaceID of the
+ * face.
+ *
+ * Clients are free to map face IDs to anything else. The most simple
+ * usage is to associate them to a (pathname,face_index) pair that is
+ * used to call @FT_New_Face. However, more complex schemes are also
+ * possible.
+ *
+ * Note that for the cache to work correctly, the face ID values must be
+ * *persistent*, which means that the contents they point to should not
+ * change at runtime, or that their value should not become invalid.
+ *
+ * If this is unavoidable (e.g., when a font is uninstalled at runtime),
+ * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
+ * the cache get rid of any references to the old @FTC_FaceID it may
+ * keep internally. Failure to do so will lead to incorrect behaviour
+ * or even crashes.
+ *
+ * To use the cache, start with calling @FTC_Manager_New to create a new
+ * @FTC_Manager object, which models a single cache instance. You can
+ * then look up @FT_Face and @FT_Size objects with
+ * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
+ *
+ * If you want to use the charmap caching, call @FTC_CMapCache_New, then
+ * later use @FTC_CMapCache_Lookup to perform the equivalent of
+ * @FT_Get_Char_Index, only much faster.
+ *
+ * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
+ * later use @FTC_ImageCache_Lookup to retrieve the corresponding
+ * @FT_Glyph objects from the cache.
+ *
+ * If you need lots of small bitmaps, it is much more memory efficient
+ * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This
+ * returns @FTC_SBitRec structures, which are used to store small
+ * bitmaps directly. (A small bitmap is one whose metrics and
+ * dimensions all fit into 8-bit integers).
+ *
+ * We hope to also provide a kerning cache in the near future.

+ * The CFF driver
+ *
+ * @abstract:
+ * Controlling the CFF driver module.
+ *
+ * @description:
+ * While FreeType's CFF driver doesn't expose API functions by itself,
+ * it is possible to control its behaviour with @FT_Property_Set and
+ * @FT_Property_Get. The list below gives the available properties
+ * together with the necessary macros and structures.
+ *
+ * The CFF driver's module name is `cff'.
+ *
+ * *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
+ *
+ * The rasterizer is positioning horizontal features (e.g., ascender
+ * height & x-height, or crossbars) on the pixel grid and minimizing the
+ * amount of antialiasing applied to them, while placing vertical
+ * features (vertical stems) on the pixel grid without hinting, thus
+ * representing the stem position and weight accurately. Sometimes the
+ * vertical stems may be only partially black. In this context,
+ * `antialiasing' means that stems are not positioned exactly on pixel
+ * borders, causing a fuzzy appearance.
+ *
+ * There are two principles behind this approach.
+ *
+ * 1) No hinting in the horizontal direction: Unlike `superhinted'
+ * TrueType, which changes glyph widths to accommodate regular
+ * inter-glyph spacing, Adobe's approach is `faithful to the design' in
+ * representing both the glyph width and the inter-glyph spacing
+ * designed for the font. This makes the screen display as close as it
+ * can be to the result one would get with infinite resolution, while
+ * preserving what is considered the key characteristics of each glyph.
+ * Note that the distances between unhinted and grid-fitted positions at
+ * small sizes are comparable to kerning values and thus would be
+ * noticeable (and distracting) while reading if hinting were applied.
+ *
+ * One of the reasons to not hint horizontally is antialiasing for LCD
+ * screens: The pixel geometry of modern displays supplies three
+ * vertical sub-pixels as the eye moves horizontally across each visible
+ * pixel. On devices where we can be certain this characteristic is
+ * present a rasterizer can take advantage of the sub-pixels to add
+ * increments of weight. In Western writing systems this turns out to
+ * be the more critical direction anyway; the weights and spacing of
+ * vertical stems (see above) are central to Armenian, Cyrillic, Greek,
+ * and Latin type designs. Even when the rasterizer uses greyscale
+ * antialiasing instead of color (a necessary compromise when one
+ * doesn't know the screen characteristics), the unhinted vertical
+ * features preserve the design's weight and spacing much better than
+ * aliased type would.
+ *
+ * 2) Alignment in the vertical direction: Weights and spacing along the
+ * y~axis are less critical; what is much more important is the visual
+ * alignment of related features (like cap-height and x-height). The
+ * sense of alignment for these is enhanced by the sharpness of grid-fit
+ * edges, while the cruder vertical resolution (full pixels instead of
+ * 1/3 pixels) is less of a problem.
+ *
+ * On the technical side, horizontal alignment zones for ascender,
+ * x-height, and other important height values (traditionally called
+ * `blue zones') as defined in the font are positioned independently,
+ * each being rounded to the nearest pixel edge, taking care of
+ * overshoot suppression at small sizes, stem darkening, and scaling.
+ *
+ * Hstems (this is, hint values defined in the font to help align
+ * horizontal features) that fall within a blue zone are said to be
+ * `captured' and are aligned to that zone. Uncaptured stems are moved
+ * in one of four ways, top edge up or down, bottom edge up or down.
+ * Unless there are conflicting hstems, the smallest movement is taken
+ * to minimize distortion.
+ *
+ * @order:
+ * hinting-engine[cff]
+ * no-stem-darkening[cff]
+ * darkening-parameters[cff]

+ *
+ * {
+ * stem width <= 0.5px: darkening amount = 0.4px

+ * stem width = 1.667px: darkening amount = 0.275px
+ * stem width >= 2.333px: darkening amount = 0px
+ * }
+ *
+ * and piecewise linear in-between. At configuration time, these four
+ * control points can be set with the macro
+ * `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'. At runtime, the control
+ * points can be changed using the `darkening-parameters' property, as
+ * the following example demonstrates.
+ *
+ * {
+ * FT_Library library;
+ * FT_Int darken_params[8] = { 500, 300, // x1, y1

+ *
+ * The x~values give the stem width, and the y~values the darkening
+ * amount. The unit is 1000th of pixels. All coordinate values must be
+ * positive; the x~values must be monotonically increasing; the
+ * y~values must be monotonically decreasing and smaller than or
+ * equal to 500 (corresponding to half a pixel); the slope of each

+ *
+ * @title:
+ * LCD Filtering
+ *
+ * @abstract:
+ * Reduce color fringes of subpixel-rendered bitmaps.
+ *
+ * @description:
+ * Subpixel rendering exploits the color-striped structure of LCD
+ * pixels, increasing the available resolution in the direction of the
+ * stripe (usually horizontal RGB) by a factor of~3. Since these
+ * subpixels are color pixels, using them unfiltered creates severe
+ * color fringes. Use the @FT_Library_SetLcdFilter API to specify a
+ * low-pass filter, which is then applied to subpixel-rendered bitmaps
+ * generated through @FT_Render_Glyph. The filter sacrifices some of
+ * the higher resolution to reduce color fringes, making the glyph image
+ * slightly blurrier. Positional improvements will remain.
+ *
+ * Note that no filter is active by default, and that this function is
+ * *not* implemented in default builds of the library. You need to
+ * #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
+ * in order to activate it and explicitly call @FT_Library_SetLcdFilter
+ * to enable it.
+ *
+ * A filter should have two properties:
+ *
+ * 1) It should be normalized, meaning the sum of the 5~components
+ * should be 256 (0x100). It is possible to go above or under this
+ * target sum, however: going under means tossing out contrast, going
+ * over means invoking clamping and thereby non-linearities that
+ * increase contrast somewhat at the expense of greater distortion
+ * and color-fringing. Contrast is better enhanced through stem
+ * darkening.
+ *
+ * 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
+ * where a~+ b~=~c. It distributes the computed coverage for one
+ * subpixel to all subpixels equally, sacrificing some won resolution
+ * but drastically reducing color-fringing. Positioning improvements
+ * remain! Note that color-fringing can only really be minimized
+ * when using a color-balanced filter and alpha-blending the glyph
+ * onto a surface in linear space; see @FT_Render_Glyph.
+ *
+ * Regarding the form, a filter can be a `boxy' filter or a `beveled'
+ * filter. Boxy filters are sharper but are less forgiving of non-ideal
+ * gamma curves of a screen (viewing angles!), beveled filters are
+ * fuzzier but more tolerant.
+ *
+ * Examples:
+ *
+ * - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
+ * normalized.
+ *
+ * - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
+ * normalized.
+ *
+ * - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
+ * balanced.
+ *
+ * - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
+ * balanced.
+ *
+ * - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
+ * balanced.
+ *
+ * - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
+ * balanced.
+ *
+ * The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
+ * @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output
+ * of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
+ *
+ * If this feature is activated, the dimensions of LCD glyph bitmaps are
+ * either wider or taller than the dimensions of the corresponding
+ * outline with regard to the pixel grid. For example, for
+ * @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
+ * 3~subpixels to the right. The bitmap offset values are adjusted
+ * accordingly, so clients shouldn't need to modify their layout and
+ * glyph positioning code when enabling the filter.
+ *
+ * It is important to understand that linear alpha blending and gamma
+ * correction is critical for correctly rendering glyphs onto surfaces
+ * without artifacts and even more critical when subpixel rendering is
+ * involved.
+ *
+ * Each of the 3~alpha values (subpixels) is independently used to blend
+ * one color channel. That is, red alpha blends the red channel of the
+ * text color with the red channel of the background pixel. The
+ * distribution of density values by the color-balanced filter assumes
+ * alpha blending is done in linear space; only then color artifacts
+ * cancel out.

+ *
+ * @description:
+ * A list of values to identify various types of LCD filters.
+ *
+ * @values:
+ * FT_LCD_FILTER_NONE ::
+ * Do not perform filtering. When used with subpixel rendering, this
+ * results in sometimes severe color fringes.
+ *
+ * FT_LCD_FILTER_DEFAULT ::
+ * The default filter reduces color fringes considerably, at the cost
+ * of a slight blurriness in the output.
+ *
+ * It is a beveled, normalized, and color-balanced five-tap filter
+ * that is more forgiving to screens with non-ideal gamma curves and
+ * viewing angles. Note that while color-fringing is reduced, it can
+ * only be minimized by using linear alpha blending and gamma
+ * correction to render glyphs onto surfaces. The default filter
+ * weights are [0x08 0x4D 0x56 0x4D 0x08].
+ *
+ * FT_LCD_FILTER_LIGHT ::
+ * The light filter is a variant that is sharper at the cost of
+ * slightly more color fringes than the default one.
+ *
+ * It is a boxy, normalized, and color-balanced three-tap filter that
+ * is less forgiving to screens with non-ideal gamma curves and
+ * viewing angles. This filter works best when the rendering system
+ * uses linear alpha blending and gamma correction to render glyphs
+ * onto surfaces. The light filter weights are
+ * [0x00 0x55 0x56 0x55 0x00].
+ *
+ * FT_LCD_FILTER_LEGACY ::
+ * This filter corresponds to the original libXft color filter. It
+ * provides high contrast output but can exhibit really bad color
+ * fringes if glyphs are not extremely well hinted to the pixel grid.
+ * In other words, it only works well if the TrueType bytecode
+ * interpreter is enabled *and* high-quality hinted fonts are used.
+ *
+ * This filter is only provided for comparison purposes, and might be
+ * disabled or stay unsupported in the future.
+ *
+ * FT_LCD_FILTER_LEGACY1 ::
+ * For historical reasons, the FontConfig library returns a different
+ * enumeration value for legacy LCD filtering. To make code work that
+ * (incorrectly) forwards FontConfig's enumeration value to
+ * @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
+ * to have another enumeration value, which is completely equal to

+ *
+ * @title:
+ * The TrueType driver
+ *
+ * @abstract:
+ * Controlling the TrueType driver module.
+ *
+ * @description:
+ * While FreeType's TrueType driver doesn't expose API functions by
+ * itself, it is possible to control its behaviour with @FT_Property_Set
+ * and @FT_Property_Get. The following lists the available properties
+ * together with the necessary macros and structures.
+ *
+ * The TrueType driver's module name is `truetype'.
+ *
+ * We start with a list of definitions, kindly provided by Greg
+ * Hitchcock.
+ *
+ * _Bi-Level_ _Rendering_
+ *
+ * Monochromatic rendering, exclusively used in the early days of
+ * TrueType by both Apple and Microsoft. Microsoft's GDI interface
+ * supported hinting of the right-side bearing point, such that the
+ * advance width could be non-linear. Most often this was done to
+ * achieve some level of glyph symmetry. To enable reasonable
+ * performance (e.g., not having to run hinting on all glyphs just to
+ * get the widths) there was a bit in the head table indicating if the
+ * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
+ * cache hinting widths across multiple sizes and device aspect ratios.
+ *
+ * _Font_ _Smoothing_
+ *
+ * Microsoft's GDI implementation of anti-aliasing. Not traditional
+ * anti-aliasing as the outlines were hinted before the sampling. The
+ * widths matched the bi-level rendering.
+ *
+ * _ClearType_ _Rendering_
+ *
+ * Technique that uses physical subpixels to improve rendering on LCD
+ * (and other) displays. Because of the higher resolution, many methods
+ * of improving symmetry in glyphs through hinting the right-side
+ * bearing were no longer necessary. This lead to what GDI calls
+ * `natural widths' ClearType, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
+ * has extra resolution, most non-linearity went away, but it is still
+ * possible for hints to change the advance widths in this mode.
+ *
+ * _ClearType_ _Compatible_ _Widths_
+ *
+ * One of the earliest challenges with ClearType was allowing the
+ * implementation in GDI to be selected without requiring all UI and
+ * documents to reflow. To address this, a compatible method of
+ * rendering ClearType was added where the font hints are executed once
+ * to determine the width in bi-level rendering, and then re-run in
+ * ClearType, with the difference in widths being absorbed in the font
+ * hints for ClearType (mostly in the white space of hints); see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
+ * definition, compatible width ClearType allows for non-linear widths,
+ * but only when the bi-level version has non-linear widths.
+ *
+ * _ClearType_ _Subpixel_ _Positioning_
+ *
+ * One of the nice benefits of ClearType is the ability to more crisply
+ * display fractional widths; unfortunately, the GDI model of integer
+ * bitmaps did not support this. However, the WPF and Direct Write
+ * frameworks do support fractional widths. DWrite calls this `natural
+ * mode', not to be confused with GDI's `natural widths'. Subpixel
+ * positioning, in the current implementation of Direct Write,
+ * unfortunately does not support hinted advance widths, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
+ * TrueType interpreter fully allows the advance width to be adjusted in
+ * this mode, just the DWrite client will ignore those changes.
+ *
+ * _ClearType_ _Backwards_ _Compatibility_
+ *
+ * This is a set of exceptions made in the TrueType interpreter to
+ * minimize hinting techniques that were problematic with the extra
+ * resolution of ClearType; see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
+ * http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+ * This technique is not to be confused with ClearType compatible
+ * widths. ClearType backwards compatibility has no direct impact on
+ * changing advance widths, but there might be an indirect impact on
+ * disabling some deltas. This could be worked around in backwards
+ * compatibility mode.
+ *
+ * _Native_ _ClearType_ _Mode_
+ *
+ * (Not to be confused with `natural widths'.) This mode removes all
+ * the exceptions in the TrueType interpreter when running with
+ * ClearType. Any issues on widths would still apply, though.
+ *

+ /**************************************************************************
+ *
+ * @property:
+ * interpreter-version
+ *
+ * @description:
+
+ * Currently, three versions are available, two representing the
+ * bytecode interpreter with subpixel hinting support (old `Infinality'
+ * code and new stripped-down and higher performance `minimal' code) and
+ * one without, respectively. The default is subpixel support if
+ * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
+ * otherwise (since it isn't available then).
+ *
+ * If subpixel hinting is on, many TrueType bytecode instructions behave
+ * differently compared to B/W or grayscale rendering (except if `native
+ * ClearType' is selected by the font). Microsoft's main idea is to
+ * render at a much increased horizontal resolution, then sampling down
+ * the created output to subpixel precision. However, many older fonts
+ * are not suited to this and must be specially taken care of by
+ * applying (hardcoded) tweaks in Microsoft's interpreter.
+ *
+ * Details on subpixel hinting and some of the necessary tweaks can be
+ * found in Greg Hitchcock's whitepaper at
+ * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
+ * Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
+ * or 6x5 supersampling) like discussed in the paper. Depending on the
+ * chosen interpreter, it simply ignores instructions on vertical stems
+ * to arrive at very similar results.
+ *
+ * The following example code demonstrates how to deactivate subpixel
+ * hinting (omitting the error handling).
+ *
+ * {
+ * FT_Library library;
+ * FT_Face face;
+ * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35;
+ *
+ *
+ * FT_Init_FreeType( &library );
+ *
+ * FT_Property_Set( library, "truetype",
+ * "interpreter-version",
+ * &interpreter_version );
+ * }
+ *
+ * @note:
+ * This property can be used with @FT_Property_Get also.
+ *
+ */
+
+
+ /**************************************************************************
+ *
+ * @enum:
+ * TT_INTERPRETER_VERSION_XXX
+ *
+ * @description:
+ * A list of constants used for the @interpreter-version property to
+ * select the hinting engine for Truetype fonts.
+ *
+ * The numeric value in the constant names represents the version
+ * number as returned by the `GETINFO' bytecode instruction.
+ *
+ * @values:
+ * TT_INTERPRETER_VERSION_35 ::
+ * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
+ * Windows~98; only grayscale and B/W rasterizing is supported.
+ *
+ * TT_INTERPRETER_VERSION_38 ::
+ * Version~38 corresponds to MS rasterizer v.1.9; it is roughly
+ * equivalent to the hinting provided by DirectWrite ClearType (as can
+ * be found, for example, in the Internet Explorer~9 running on
+ * Windows~7). It is used in FreeType to select the `Infinality'
+ * subpixel hinting code. The code may be removed in a future
+ * version.
+ *
+ * TT_INTERPRETER_VERSION_40 ::
+ * Version~40 corresponds to MS rasterizer v.2.1; it is roughly
+ * equivalent to the hinting provided by DirectWrite ClearType (as can
+ * be found, for example, in Microsoft's Edge Browser on Windows~10).
+ * It is used in FreeType to select the `minimal' subpixel hinting
+ * code, a stripped-down and higher performance version of the
+ * `Infinality' code.
+ *
+ * @note:
+ * This property controls the behaviour of the bytecode interpreter
+ * and thus how outlines get hinted. It does *not* control how glyph
+ * get rasterized! In particular, it does not control subpixel color
+ * filtering.
+ *
+ * If FreeType has not been compiled with the configuration option
+ * FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
+ * an `FT_Err_Unimplemented_Feature' error.
+ *
+ * Depending on the graphics framework, Microsoft uses different
+ * bytecode and rendering engines. As a consequence, the version
+ * numbers returned by a call to the `GETINFO' bytecode instruction are
+ * more convoluted than desired.
+ *
+ * Here are two tables that try to shed some light on the possible
+ * values for the MS rasterizer engine, together with the additional
+ * features introduced by it.
+ *
+ * {
+ * GETINFO framework version feature
+ * -------------------------------------------------------------------
+ * 3 GDI (Win 3.1), v1.0 16-bit, first version
+ * TrueImage
+ * 33 GDI (Win NT 3.1), v1.5 32-bit
+ * HP Laserjet
+ * 34 GDI (Win 95) v1.6 font smoothing,
+ * new SCANTYPE opcode
+ * 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
+ * bits in composite glyphs
+ * 36 MGDI (Win CE 2) v1.6+ classic ClearType
+ * 37 GDI (XP and later), v1.8 ClearType
+ * GDI+ old (before Vista)
+ * 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
+ * WPF Y-direction ClearType,
+ * additional error checking
+ * 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
+ * in GETINFO opcode,
+ * bug fixes
+ * 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
+ * DWrite (Win 8) in GETINFO opcode,
+ * Gray ClearType
+ * }
+ *
+ * The `version' field gives a rough orientation only, since some
+ * applications provided certain features much earlier (as an example,
+ * Microsoft Reader used subpixel and Y-direction ClearType already in
+ * Windows 2000). Similarly, updates to a given framework might include
+ * improved hinting support.
+ *
+ * {
+ * version sampling rendering comment
+ * x y x y
+ * --------------------------------------------------------------
+ * v1.0 normal normal B/W B/W bi-level
+ * v1.6 high high gray gray grayscale
+ * v1.8 high normal color-filter B/W (GDI) ClearType
+ * v1.9 high high color-filter gray Color ClearType
+ * v2.1 high normal gray B/W Gray ClearType
+ * v2.1 high high gray gray Gray ClearType
+ * }
+ *
+ * Color and Gray ClearType are the two available variants of
+ * `Y-direction ClearType', meaning grayscale rasterization along the
+ * Y-direction; the name used in the TrueType specification for this
+ * feature is `symmetric smoothing'. `Classic ClearType' is the
+ * original algorithm used before introducing a modified version in
+ * Win~XP. Another name for v1.6's grayscale rendering is `font
+ * smoothing', and `Color ClearType' is sometimes also called `DWrite
+ * ClearType'. To differentiate between today's Color ClearType and the
+ * earlier ClearType variant with B/W rendering along the vertical axis,
+ * the latter is sometimes called `GDI ClearType'.
+ *
+ * `Normal' and `high' sampling describe the (virtual) resolution to
+ * access the rasterized outline after the hinting process. `Normal'
+ * means 1 sample per grid line (i.e., B/W). In the current Microsoft
+ * implementation, `high' means an extra virtual resolution of 16x16 (or

+ * After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
+ * lines for color filtering if Color ClearType is activated.
+ *
+ * Note that `Gray ClearType' is essentially the same as v1.6's
+ * grayscale rendering. However, the GETINFO instruction handles it
+ * differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
+ * returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
+ * and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
+ * the version~1 gasp table exclusively (like Color ClearType), while
+ * v1.6 only respects the values of version~0 (bits 0 and~1).
+ *
+ * Keep in mind that the features of the above interpreter versions
+ * might not map exactly to FreeType features or behavior because it is
+ * a fundamentally different library with different internals.

+ *
+ * @values:
+ * FT_WinFNT_ID_DEFAULT ::
+ * This is used for font enumeration and font creation as a
+ * `don't care' value. Valid font files don't contain this value.
+ * When querying for information about the character set of the font
+ * that is currently selected into a specified device context, this

+ * Mac Roman encoding.
+ *
+ * FT_WinFNT_ID_OEM ::
+ * From Michael Pöttgen <michael@poettgen.de>:
+ *
+ * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
+ * is used for the charset of vector fonts, like `modern.fon',
+ * `roman.fon', and `script.fon' on Windows.
+ *
+ * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
+ * specifies a character set that is operating-system dependent.
+ *
+ * The `IFIMETRICS' documentation from the `Windows Driver
+ * Development Kit' says: This font supports an OEM-specific
+ * character set. The OEM character set is system dependent.
+ *
+ * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
+ * second default codepage that most international versions of
+ * Windows have. It is one of the OEM codepages from
+ *
+ * https://msdn.microsoft.com/en-us/goglobal/bb964655,
+ *
+ * and is used for the `DOS boxes', to support legacy applications.
+ * A German Windows version for example usually uses ANSI codepage
+ * 1252 and OEM codepage 850.
+ *
+ * FT_WinFNT_ID_CP874 ::
+ * A superset of Thai TIS 620 and ISO 8859-11.
+ *
+ * FT_WinFNT_ID_CP932 ::
+ * A superset of Japanese Shift-JIS (with minor deviations).
+ *
+ * FT_WinFNT_ID_CP936 ::
+ * A superset of simplified Chinese GB 2312-1980 (with different
+ * ordering and minor deviations).
+ *
+ * FT_WinFNT_ID_CP949 ::
+ * A superset of Korean Hangul KS~C 5601-1987 (with different
+ * ordering and minor deviations).
+ *
+ * FT_WinFNT_ID_CP950 ::
+ * A superset of traditional Chinese Big~5 ETen (with different
+ * ordering and minor deviations).
+ *
+ * FT_WinFNT_ID_CP1250 ::
+ * A superset of East European ISO 8859-2 (with slightly different
+ * ordering).
+ *
+ * FT_WinFNT_ID_CP1251 ::
+ * A superset of Russian ISO 8859-5 (with different ordering).
+ *
+ * FT_WinFNT_ID_CP1252 ::
+ * ANSI encoding. A superset of ISO 8859-1.
+ *
+ * FT_WinFNT_ID_CP1253 ::
+ * A superset of Greek ISO 8859-7 (with minor modifications).
+ *
+ * FT_WinFNT_ID_CP1254 ::

+ /* aggressively the glyphs in the face, and thus can be */

+ /* hints is really small). */
+ /* */
+ /* - glyph hints: These describe some important features of the glyph */
+ /* outline, as well as how to align them. They are */
+ /* generally much faster to compute than global hints. */
+ /* */
+ /* The current FreeType auto-hinter does a pretty good job while */
+ /* performing fast computations for both global and glyph hints. */
+ /* However, we might be interested in introducing more complex and */
+ /* powerful algorithms in the future, like the one described in the John */
+ /* D. Hobby paper, which unfortunately requires a lot more horsepower. */
+ /* */
+ /* Because a sufficiently sophisticated font management system would */

+ /* global hints every time the same face is re-opened. */
+ /* */
+ /* We thus provide the ability to cache global hints outside of the face */
+ /* object, in order to speed up font re-opening time. Of course, this */
+ /* feature is purely optional, so most client programs won't even notice */

+ /* */
+ /* I initially thought that it would be a good idea to cache the glyph */

+
+
+// This file contains data specific to blue zones. It gets processed by
+// a script to simulate `jagged arrays', with enumeration values holding
+// offsets into the arrays.
+//
+// The format of the file is rather simple: A section starts with three
+// labels separated by whitespace and followed by a colon (everything in a
+// single line); the first label gives the name of the enumeration template,
+// the second the name of the array template, and the third the name of the
+// `maximum' template. The script then fills the corresponding templates
+// (indicated by `@' characters around the name).
+//
+// A section contains one or more data records. Each data record consists
+// of two or more lines. The first line holds the enumeration name, and the
+// remaining lines the corresponding array data.
+//
+// There are two possible representations for array data.
+//
+// - A string of characters or character clusters (for example, representing
+// Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
+// quotes, using C syntax, where the elements are separated by spaces.
+// There can be only one string per line, thus the starting and ending
+// double quote must be the first and last character in the line,
+// respectively, ignoring whitespace before and after the string. If
+// there are multiple strings (in multiple lines), they are concatenated
+// to a single string. In the output, a string gets represented as a
+// series of singles bytes, followed by a zero byte. The enumeration
+// values simply hold byte offsets to the start of the corresponding
+// strings.
+//
+// For strings, the `maximum' template holds the maximum number of
+// non-space characters in all strings.
+//
+// - Data blocks enclosed in balanced braces, which get copied verbatim and
+// which can span multiple lines. The opening brace of a block must be
+// the first character of a line (ignoring whitespace), and the closing
+// brace the last (ignoring whitespace also). The script appends a comma
+// character after each block and counts the number of blocks to set the
+// enumeration values.
+//
+// For data blocks, the `maximum' template holds the maximum number of
+// array elements.
+//
+// A section can contain either strings only or data blocks only.
+//
+// A comment line starts with `//'; it gets removed. A preprocessor
+// directive line (using the standard syntax of `cpp') starts with `#' and
+// gets copied verbatim to both the enumeration and the array. Whitespace
+// outside of a string is insignificant.
+//
+// Preprocessor directives are ignored while the script computes maximum

+// The blue zone stringsets, as used in the script styles, cf. `afstyles.h'.
+//
+// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
+// explanations.
+//
+// A blue zone in general is defined by a reference and an overshoot line.
+// During the hinting process, all coordinate values between those two lines
+// are set equal to the reference value, provided that the blue zone is not
+// wider than 0.75 pixels (otherwise the blue zone gets ignored). All
+// entries must have `AF_BLUE_STRING_MAX' as the final line.
+//
+// During the glyph analysis, edges are sorted from bottom to top, and then
+// sequentially checked, edge by edge, against the blue zones in the order
+// given below.
+//
+//
+// latin auto-hinter
+// -----------------
+//
+// Characters in a blue string are automatically classified as having a flat
+// (reference) or a round (overshoot) extremum. The blue zone is then set
+// up by the mean values of all flat extrema and all round extrema,
+// respectively. Only horizontal blue zones (i.e., adjusting vertical
+// coordinate values) are supported.
+//
+// Some scripts like Khmer need character composition to get all necessary
+// blue zones, since Unicode only provides an abstract data model that
+// doesn't represent all possible glyph shapes. For such character
+// clusters, the HarfBuzz library is used to convert them into the
+// corresponding glyphs. The largest glyph element (where `largest' can be
+// either `largest ascender' or `largest descender') then defines the
+// corresponding flat or round extremum.
+//
+// For the latin auto-hinter, the overshoot should be larger than the
+// reference for top zones, and vice versa for bottom zones.
+//
+// LATIN_TOP
+// Take the maximum flat and round coordinate values of the blue string
+// characters for computing the blue zone's reference and overshoot
+// values.
+//
+// If not set, take the minimum values.
+//
+// Mutually exclusive with `LATIN_SUB_TOP'.
+//
+// LATIN_SUB_TOP
+// For all glyphs of a character cluster, compute the maximum flat
+// and round coordinate values of each component, then take the
+// smallest of the maximum values. The idea is to get the top of
+// subscript glyphs, as used in Khmer, for example. Note that
+// this mechanism doesn't work for ordinary ligatures.
+//
+// This flags indicates a secondary blue zone: It gets removed if
+// there is a non-LATIN_SUB_TOP blue zone at the same coordinate
+// value (after scaling).
+//
+// Mutually exclusive with `LATIN_TOP'.
+//
+// LATIN_NEUTRAL
+// Ignore round extrema and define the blue zone with flat values only.
+// Both top and bottom of contours can match. This is useful for
+// scripts like Devanagari where vowel signs attach to the base
+// character and are implemented as components of composite glyphs.
+//
+// If not set, both round and flat extrema are taken into account.
+// Additionally, only the top or the bottom of a contour can match,
+// depending on the LATIN_TOP flag.
+//
+// Neutral blue zones should always follow non-neutral blue zones.
+//
+// LATIN_X_HEIGHT
+// Scale all glyphs vertically from the corresponding script to make the
+// reference line of this blue zone align on the grid. The scaling
+// takes place before all other blue zones get aligned to the grid.
+// Only one blue character string of a script style can have this flag.
+//
+// LATIN_LONG
+// Apply an additional constraint for blue zone values: Don't
+// necessarily use the extremum as-is but a segment of the topmost (or
+// bottommost) contour that is longer than a heuristic threshold, and
+// which is not too far away vertically from the real extremum. This
+// ensures that small bumps in the outline are ignored (for example, the
+// `vertical serifs' found in many Hebrew glyph designs).
+//
+// The segment must be at least EM/25 font units long, and the distance
+// to the extremum must be smaller than EM/4.
+//
+//
+// cjk auto-hinter
+// ---------------
+//
+// Characters in a blue string are *not* automatically classified. Instead,
+// first come the characters used for the overshoot value, then the
+// character `|', then the characters used for the reference value
+// (everything separated by space characters). The blue zone is then set up
+// by the mean values of all reference values and all overshoot values,
+// respectively. Both horizontal and vertical blue zones (i.e., adjusting
+// vertical and horizontal coordinate values, respectively) are supported.
+//
+// For the cjk auto-hinter, the overshoot should be smaller than the
+// reference for top zones, and vice versa for bottom zones.
+//
+// CJK_TOP
+// Take the maximum flat and round coordinate values of the blue string
+// characters. If not set, take the minimum values.
+//
+// CJK_RIGHT
+// A synonym for CJK_TOP. If CJK_HORIZ is set, this flag indicates the
+// right blue zone, taking horizontal maximum values.
+//
+// CJK_HORIZ
+// Define a blue zone for horizontal hinting (i.e., vertical blue
+// zones). If not set, this is a blue zone for vertical hinting.

+ * The following explanations are mostly taken from the article

+ *
+ *
+ * Segments
+ *
+ * `af_{cjk,latin,...}_hints_compute_segments' are the functions to
+ * find segments in an outline.
+ *
+ * A segment is a series of at least two consecutive points that are
+ * approximately aligned along a coordinate axis. The analysis to do
+ * so is specific to a writing system.
+ *
+ *
+ * Edges
+ *
+ * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
+ * edges.
+ *
+ * As soon as segments are defined, the auto-hinter groups them into
+ * edges. An edge corresponds to a single position on the main
+ * dimension that collects one or more segments (allowing for a small
+ * threshold).
+ *
+ * As an example, the `latin' writing system first tries to grid-fit
+ * edges, then to align segments on the edges unless it detects that
+ * they form a serif.

+ * D E
+ *
+ *
+ * Stems
+ *
+ * Stems are detected by `af_{cjk,latin,...}_hint_edges'.
+ *
+ * Segments need to be `linked' to other ones in order to detect stems.
+ * A stem is made of two segments that face each other in opposite
+ * directions and that are sufficiently close to each other. Using
+ * vocabulary from the TrueType specification, stem segments form a
+ * `black distance'.
+ *
+ * In the above ASCII drawing, the horizontal segments are BC, DE, and
+ * FG; the vertical segments are AB, CD, EF, and GH.
+ *
+ * Each segment has at most one `best' candidate to form a black
+ * distance, or no candidate at all. Notice that two distinct segments
+ * can have the same candidate, which frequently means a serif.
+ *
+ * A stem is recognized by the following condition:
+ *
+ * best segment_1 = segment_2 && best segment_2 = segment_1
+ *
+ * The best candidate is stored in field `link' in structure
+ * `AF_Segment'.
+ *
+ * In the above ASCII drawing, the best candidate for both AB and CD is
+ * GH, while the best candidate for GH is AB. Similarly, the best
+ * candidate for EF and GH is AB, while the best candidate for AB is
+ * GH.
+ *
+ * The detection and handling of stems is dependent on the writing
+ * system.
+ *
+ *
+ * Serifs
+ *
+ * Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
+ *
+ * In comparison to a stem, a serif (as handled by the auto-hinter
+ * module that takes care of the `latin' writing system) has
+ *
+ * best segment_1 = segment_2 && best segment_2 != segment_1
+ *
+ * where segment_1 corresponds to the serif segment (CD and EF in the
+ * above ASCII drawing).
+ *
+ * The best candidate is stored in field `serif' in structure
+ * `AF_Segment' (and `link' is set to NULL).
+ *
+ *
+ * Touched points
+ *
+ * A point is called `touched' if it has been processed somehow by the
+ * auto-hinter. It basically means that it shouldn't be moved again
+ * (or moved only under certain constraints to preserve the already
+ * applied processing).
+ *
+ *
+ * Flat and round segments
+ *
+ * Segments are `round' or `flat', depending on the series of points
+ * that define them. A segment is round if the next and previous point
+ * of an extremum (which can be either a single point or sequence of
+ * points) are both conic or cubic control points. Otherwise, a
+ * segment with an extremum is flat.
+ *
+ *
+ * Strong Points
+ *
+ * Experience has shown that points not part of an edge need to be
+ * interpolated linearly between their two closest edges, even if these
+ * are not part of the contour of those particular points. Typical
+ * candidates for this are
+ *
+ * - angle points (i.e., points where the `in' and `out' direction
+ * differ greatly)
+ *
+ * - inflection points (i.e., where the `in' and `out' angles are the
+ * same, but the curvature changes sign) [currently, such points
+ * aren't handled specially in the auto-hinter]
+ *
+ * `af_glyph_hints_align_strong_points' is the function that takes
+ * care of such situations; it is equivalent to the TrueType `IP'
+ * hinting instruction.
+ *
+ *
+ * Weak Points
+ *
+ * Other points in the outline must be interpolated using the
+ * coordinates of their previous and next unfitted contour neighbours.
+ * These are called `weak points' and are touched by the function
+ * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
+ * hinting instruction. Typical candidates are control points and
+ * points on the contour without a major direction.
+ *
+ * The major effect is to reduce possible distortion caused by
+ * alignment of edges and strong points, thus weak points are processed
+ * after strong points.

+ * could be the same. However, the auto-hinter is completely
+ * agnostic of OpenType features after the feature analysis has been
+ * completed: The engine then simply receives a glyph index and returns a
+ * hinted and usually rendered glyph.
+ *
+ * Consider the superscript feature of font `pala.ttf': Some of the
+ * glyphs are `real', this is, they have a zero vertical offset, but
+ * most of them are small caps glyphs shifted up to the superscript
+ * position (this is, the `sups' feature is present in both the GSUB and
+ * GPOS tables). The code for blue zones computation actually uses a
+ * feature's y offset so that the `real' glyphs get correct hints. But
+ * later on it is impossible to decide whether a glyph index belongs to,
+ * say, the small caps or superscript feature.
+ *
+ * For this reason, we don't assign a style to a glyph if the current
+ * feature covers the glyph in both the GSUB and the GPOS tables. This
+ * is quite a broad condition, assuming that
+ *
+ * (a) glyphs that get used in multiple features are present in a
+ * feature without vertical shift,
+ *
+ * and
+ *
+ * (b) a feature's GPOS data really moves the glyph vertically.
+ *
+ * Not fulfilling condition (a) makes a font larger; it would also
+ * reduce the number of glyphs that could be addressed directly without
+ * using OpenType features, so this assumption is rather strong.
+ *
+ * Condition (b) is much weaker, and there might be glyphs which get
+ * missed. However, the OpenType features we are going to handle are
+ * primarily located in GSUB, and HarfBuzz doesn't provide an API to
+ * directly get the necessary information from the GPOS table. A
+ * possible solution might be to directly parse the GPOS table to find
+ * out whether a glyph gets shifted vertically, but this is something I
+ * would like to avoid if not really necessary.
+ *
+ * Note that we don't follow this logic for the default coverage.
+ * Complex scripts like Devanagari have mandatory GPOS features to
+ * position many glyph elements, using mark-to-base or mark-to-ligature
+ * tables; the number of glyphs missed due to condition (b) would be far
+ * too large.

+ * Usually, a font contains more glyphs than can be addressed by its
+ * character map.
+ *
+ * In the PostScript font world, encoding vectors specific to a given
+ * task are used to select such glyphs, and these glyphs can be often
+ * recognized by having a suffix in its glyph names. For example, a
+ * superscript glyph `A' might be called `A.sup'. Unfortunately, this
+ * naming scheme is not standardized and thus unusable for us.
+ *
+ * In the OpenType world, a better solution was invented, namely
+ * `features', which cleanly separate a character's input encoding from
+ * the corresponding glyph's appearance, and which don't use glyph names
+ * at all. For our purposes, and slightly generalized, an OpenType
+ * feature is a name of a mapping that maps character codes to
+ * non-standard glyph indices (features get used for other things also).
+ * For example, the `sups' feature provides superscript glyphs, thus
+ * mapping character codes like `A' or `B' to superscript glyph
+ * representation forms. How this mapping happens is completely
+ * uninteresting to us.
+ *
+ * For the auto-hinter, a `coverage' represents all glyphs of an OpenType
+ * feature collected in a set (as listed below) that can be hinted
+ * together. To continue the above example, superscript glyphs must not
+ * be hinted together with normal glyphs because the blue zones
+ * completely differ.
+ *
+ * Note that FreeType itself doesn't compute coverages; it only provides
+ * the glyphs addressable by the default Unicode character map. Instead,
+ * we use the HarfBuzz library (if available), which has many functions
+ * exactly for this purpose.
+ *
+ * AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
+ * listed separately (including the glyphs addressable by the character
+ * map). In case HarfBuzz isn't available, it exactly covers the glyphs
+ * addressable by the character map.

+ /*
+ Notes
+
+ Mac suitcase files can (and often do!) contain multiple fonts. To
+ support this I use the face_index argument of FT_(Open|New)_Face()
+ functions, and pretend the suitcase file is a collection.
+
+ Warning: fbit and NFNT bitmap resources are not supported yet. In old
+ sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+ resources instead of the `bdat' table in the sfnt resource. Therefore,
+ face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+ resource is unavailable at present.
+
+ The Mac FOND support works roughly like this:
+
+ - Check whether the offered stream points to a Mac suitcase file. This
+ is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
+ stream that gets passed to our init_face() routine is a stdio stream,
+ which isn't usable for us, since the FOND resources live in the
+ resource fork. So we just grab the stream->pathname field.
+
+ - Read the FOND resource into memory, then check whether there is a
+ TrueType font and/or(!) a Type 1 font available.
+
+ - If there is a Type 1 font available (as a separate `LWFN' file), read
+ its data into memory, massage it slightly so it becomes PFB data, wrap
+ it into a memory stream, load the Type 1 driver and delegate the rest
+ of the work to it by calling FT_Open_Face(). (XXX TODO: after this
+ has been done, the kerning data from the FOND resource should be
+ appended to the face: On the Mac there are usually no AFM files
+ available. However, this is tricky since we need to map Mac char
+ codes to ps glyph names to glyph ID's...)
+
+ - If there is a TrueType font (an `sfnt' resource), read it into memory,
+ wrap it into a memory stream, load the TrueType driver and delegate
+ the rest of the work to it, by calling FT_Open_Face().
+
+ - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+ itself, even though it doesn't contains `POST' resources. To handle
+ this special case without opening the file an extra time, we just
+ ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+ available.

+
+
+ /*
+ *
+ * FTC_GCache is an _abstract_ cache object optimized to store glyph
+ * data. It works as follows:
+ *
+ * - It manages FTC_GNode objects. Each one of them can hold one or more
+ * glyph `items'. Item types are not specified in the FTC_GCache but
+ * in classes that extend it.
+ *
+ * - Glyph attributes, like face ID, character size, render mode, etc.,
+ * can be grouped into abstract `glyph families'. This avoids storing
+ * the attributes within the FTC_GCache, since it is likely that many
+ * FTC_GNodes will belong to the same family in typical uses.
+ *
+ * - Each FTC_GNode is thus an FTC_Node with two additional fields:
+ *
+ * * gindex: A glyph index, or the first index in a glyph range.
+ * * family: A pointer to a glyph `family'.
+ *
+ * - Family types are not fully specific in the FTC_Family type, but
+ * by classes that extend it.
+ *
+ * Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
+ * They share an FTC_Family sub-class called FTC_BasicFamily which is
+ * used to store the following data: face ID, pixel/point sizes, load
+ * flags. For more details see the file `src/cache/ftcbasic.c'.
+ *
+ * Client applications can extend FTC_GNode with their own FTC_GNode
+ * and FTC_Family sub-classes to implement more complex caches (e.g.,
+ * handling automatic synthesis, like obliquing & emboldening, colored
+ * glyphs, etc.).
+ *
+ * See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
+ * `ftcsbits.h', which both extend FTC_GCache with additional
+ * optimizations.
+ *
+ * A typical FTC_GCache implementation must provide at least the
+ * following:
+ *
+ * - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
+ * my_node_new (must call FTC_GNode_Init)
+ * my_node_free (must call FTC_GNode_Done)
+ * my_node_compare (must call FTC_GNode_Compare)
+ * my_node_remove_faceid (must call ftc_gnode_unselect in case
+ * of match)
+ *
+ * - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
+ * my_family_compare
+ * my_family_init
+ * my_family_reset (optional)
+ * my_family_done
+ *
+ * - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
+ * data.
+ *
+ * - Constant structures for a FTC_GNodeClass.
+ *
+ * - MyCacheNew() can be implemented easily as a call to the convenience
+ * function FTC_GCache_New.
+ *
+ * - MyCacheLookup with a call to FTC_GCache_Lookup. This function will
+ * automatically:
+ *
+ * - Search for the corresponding family in the cache, or create
+ * a new one if necessary. Put it in FTC_GQUERY(myquery).family
+ *
+ * - Call FTC_Cache_Lookup.
+ *
+ * If it returns NULL, you should create a new node, then call
+ * ftc_cache_add as usual.

+ /* */
+ /* - Manage one or more cache objects. Each cache is in charge of */
+ /* holding a varying number of `cache nodes'. Each cache node */

+ *
+ * However, we need to `lock' the node before this operation to
+ * prevent it from being flushed within the loop.
+ *
+ * When we exit the loop, we unlock the node, then check the `error'
+ * variable. If it is non-zero, this means that the cache was
+ * completely flushed and that no usable memory was found to load
+ * the bitmap.
+ *
+ * We then prefer to return a value of 0 (i.e., NO MATCH). This
+ * ensures that the caller will try to allocate a new node.
+ * This operation consequently _fail_ and the lookup function
+ * returns the appropriate OOM error code.

+ * tag `unavailable' bitmaps in the array. We should never try

+ * carefully managed and preserved. However, it is convenient for us to

+ * When we assign an error code we are thus `throwing' an error.

+ * The perservation of an error code is done by coding convention.
+ * Upon a function call if the error code is anything other than

+ * will return without altering that error. This will allow the
+ * error to propagate and be handled at the appropriate location in
+ * the code.
+ *
+ * This allows a style of code where the error code is initialized
+ * up front and a block of calls are made with the error code only
+ * being checked after the block. If a new error occurs, the original
+ * error will be preserved and a functional no-op should result in any
+ * subsequent function that has an initial error code not equal to
+ * `FT_Err_Ok'.
+ *
+ * Errors are encoded by calling the `FT_THROW' macro. For example,

+gxvalid: TrueType GX validator
+==============================
+
+
+1. What is this
+---------------
+
+ `gxvalid' is a module to validate TrueType GX tables: a collection of
+ additional tables in TrueType font which are used by `QuickDraw GX
+ Text', Apple Advanced Typography (AAT). In addition, gxvalid can
+ validates `kern' tables which have been extended for AAT. Like the
+ otvalid module, gxvalid uses Freetype 2's validator framework
+ (ftvalid).
+
+ You can link gxvalid with your program; before running your own layout
+ engine, gxvalid validates a font file. As the result, you can remove
+ error-checking code from the layout engine. It is also possible to
+ use gxvalid as a stand-alone font validator; the `ftvalid' test
+ program included in the ft2demo bundle calls gxvalid internally.
+ A stand-alone font validator may be useful for font developers.
+
+ This documents documents the following issues.
+
+ - supported TrueType GX tables
+ - fundamental validation limitations
+ - permissive error handling of broken GX tables
+ - `kern' table issue.
+
+
+2. Supported tables
+-------------------
+
+ The following GX tables are currently supported.
+
+ bsln
+ feat
+ just
+ kern(*)
+ lcar
+ mort
+ morx
+ opbd
+ prop
+ trak
+
+ The following GX tables are currently unsupported.
+
+ cvar
+ fdsc
+ fmtx
+ fvar
+ gvar
+ Zapf
+
+ The following GX tables won't be supported.
+
+ acnt(**)
+ hsty(***)
+
+ The following undocumented tables in TrueType fonts designed for Apple
+ platform aren't handled either.
+
+ addg
+ CVTM
+ TPNM
+ umif
+
+
+ *) The `kern' validator handles both the classic and the new kern
+ formats; the former is supported on both Microsoft and Apple
+ platforms, while the latter is supported on Apple platforms.
+
+ **) `acnt' tables are not supported by currently available Apple font
+ tools.
+
+ ***) There is one more Apple extension, `hsty', but it is for
+ Newton-OS, not GX (Newton-OS is a platform by Apple, but it can
+ use sfnt- housed bitmap fonts only). Therefore, it should be
+ excluded from `Apple platform' in the context of TrueType.
+ gxvalid ignores it as Apple font tools do so.
+
+
+ We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS
+ 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition,
+ we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh
+ fonts (designed for Windows and MacOS dual platforms). The number of
+ fonts including TrueType GX tables are as follows.
+
+ bsln: 76
+ feat: 191
+ just: 84
+ kern: 59
+ lcar: 4
+ mort: 326
+ morx: 19
+ opbd: 4
+ prop: 114
+ trak: 16
+
+ Dynalab and Ricoh fonts don't have GX tables except of `feat' and
+ `mort'.
+
+
+3. Fundamental validation limitations
+-------------------------------------
+
+ TrueType GX provides layout information to libraries for font
+ rasterizers and text layout. gxvalid can check whether the layout
+ data in a font is conformant to the TrueType GX format specified by
+ Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses
+ the stored information.
+
+ 3-1. Validation of State Machine activity
+ -----------------------------------------
+
+ QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
+ features, and TrueType GX stores the state transition diagram of
+ this `State Machine' in a `StateTable' data structure. While the
+ State Machine receives a series of glyph IDs, the State Machine
+ starts with `start of text' state, walks around various states and
+ generates various layout information to the renderer, and finally
+ reaches the `end of text' state.
+
+ gxvalid can check essential errors like:
+
+ - possibility of state transitions to undefined states
+ - existence of glyph IDs that the State Machine doesn't know how
+ to handle
+ - the State Machine cannot compute the layout information from
+ given diagram
+
+ These errors can be checked within finite steps, and without the
+ State Machine itself, because these are `expression' errors of state
+ transition diagram.
+
+ There is no limitation about how long the State Machine walks
+ around, so validation of the algorithm in the state transition
+ diagram requires infinite steps, even if we had a State Machine in
+ gxvalid. Therefore, the following errors and problems cannot be
+ checked.
+
+ - existence of states which the State Machine never transits to
+ - the possibility that the State Machine never reaches `end of
+ text'
+ - the possibility of stack underflow/overflow in the State Machine
+ (in ligature and contextual glyph substitutions, the State
+ Machine can store 16 glyphs onto its stack)
+
+ In addition, gxvalid doesn't check `temporary glyph IDs' used in the
+ chained State Machines (in `mort' and `morx' tables). If a layout
+ feature is implemented by a single State Machine, a glyph ID
+ converted by the State Machine is passed to the glyph renderer, thus
+ it should not point to an undefined glyph ID. But if a layout
+ feature is implemented by chained State Machines, a component State
+ Machine (if it is not the final one) is permitted to generate
+ undefined glyph IDs for temporary use, because it is handled by next
+ component State Machine and not by the glyph renderer. To validate
+ such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
+ which can occur in the output of the previous State Machine and
+ search them in the `ClassTable' structure of the current State
+ Machine. It is too complex to list all possible glyph IDs from the
+ StateTable, especially from a ligature substitution table.
+
+ 3-2. Validation of relationship between multiple layout features
+ ----------------------------------------------------------------
+
+ gxvalid does not validate the relationship between multiple layout
+ features at all.
+
+ If multiple layout features are defined in TrueType GX tables,
+ possible interactions, overrides, and conflicts between layout
+ features are implicitly given in the font too. For example, there
+ are several predefined spacing control features:
+
+ - Text Spacing (Proportional/Monospace/Half-width/Normal)
+ - Number Spacing (Monospaced-numbers/Proportional-numbers)
+ - Kana Spacing (Full-width/Proportional)
+ - Ideographic Spacing (Full-width/Proportional)
+ - CJK Roman Spacing (Half-width/Proportional/Default-roman
+ /Full-width-roman/Proportional)
+
+ If all layout features are independently managed, we can activate
+ inconsistent typographic rules like `Text Spacing=Monospace' and
+ `Ideographic Spacing=Proportional' at the same time.
+
+ The combinations of layout features is managed by a 32bit integer
+ (one bit each for selector setting), so we can define relationships
+ between up to 32 features, theoretically. But if one feature
+ setting affects another feature setting, we need typographic
+ priority rules to validate the relationship. Unfortunately, the
+ TrueType GX format specification does not give such information even
+ for predefined features.
+
+
+4. Permissive error handling of broken GX tables
+------------------------------------------------
+
+ When Apple's font rendering system finds an inconsistency, like a
+ specification violation or an unspecified value in a TrueType GX
+ table, it does not always return error. In most cases, the rendering
+ engine silently ignores such wrong values or even whole tables. In
+ fact, MacOS is shipped with fonts including broken GX/AAT tables, but
+ no harmful effects due to `officially broken' fonts are observed by
+ end-users.
+
+ gxvalid is designed to continue the validation process as long as
+ possible. When gxvalid find wrong values, gxvalid warns it at least,
+ and takes a fallback procedure if possible. The fallback procedure
+ depends on the debug level.
+
+ We used the following three tools to investigate Apple's error handling.
+
+ - FontValidator (for MacOS 8.5 - 9.2) resource fork font
+ - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt
+ - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt
+
+ However, all tests were done on a PowerPC based Macintosh; at present,
+ we have not checked those tools on a m68k-based Macintosh.
+
+ In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS
+ 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts
+ are distributed officially, but many broken GX/AAT tables were found
+ by Apple's font tools. In the following, we list typical violation of
+ the GX specification, in fonts officially distributed with those Apple
+ systems.
+
+ 4-1. broken BinSrchHeader (19/183)
+ ----------------------------------
+
+ `BinSrchHeader' is a header of a data array for m68k platforms to
+ access memory efficiently. Although there are only two independent
+ parameters for real (`unitSize' and `nUnits'), BinSrchHeader has
+ three additional parameters which can be calculated from `unitSize'
+ and `nUnits', for fast setup. Apple font tools ignore them
+ silently, so gxvalid warns if it finds and inconsistency, and always
+ continues validation. The additional parameters are ignored
+ regardless of the consistency.
+
+ 19 fonts include such inconsistencies; all breaks are in the
+ BinSrchHeader structure of the `kern' table.
+
+ 4-2. too-short LookupTable (5/183)
+ ----------------------------------
+
+ LookupTable format 0 is a simple array to get a value from a given
+ GID (glyph ID); the index of this array is a GID too. Therefore,
+ the length of the array is expected to be same as the maximum GID
+ value defined in the `maxp' table, but there are some fonts whose
+ LookupTable format 0 is too short to cover all GIDs. FontValidator
+ ignores this error silently, ftxvalidator and ftxdumperfuser both
+ warn and continue. Similar problems are found in format 3 subtables
+ of `kern'. gxvalid warns always and abort if the validation level
+ is set to FT_VALIDATE_PARANOID.
+
+ 5 fonts include too-short kern format 0 subtables.
+ 1 font includes too-short kern format 3 subtable.
+
+ 4-3. broken LookupTable format 2 (1/183)
+ ----------------------------------------
+
+ LookupTable format 2, subformat 4 covers the GID space by a
+ collection of segments which are specified by `firstGlyph' and
+ `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in
+ reverse order, so the segment specification is broken. Apple font
+ tools ignore this error silently; a broken segment is ignored as if
+ it did not exist. gxvalid warns and normalize the segment at
+ FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or
+ abort at FT_VALIDATE_PARANOID.
+
+ 1 font includes broken LookupTable format 2, in the `just' table.
+
+ *) It seems that all fonts manufactured by ITC for AppleWorks have
+ this error.
+
+ 4-4. bad bracketing in glyph property (14/183)
+ ----------------------------------------------
+
+ GX/AAT defines a `bracketing' property of the glyphs in the `prop'
+ table, to control layout features of strings enclosed inside and
+ outside of brackets. Some fonts give inappropriate bracket
+ properties to glyphs. Apple font tools warn about this error;
+ gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
+
+ 14 fonts include wrong bracket properties.
+
+
+ 4-5. invalid feature number (117/183)
+ -------------------------------------
+
+ The GX/AAT extension can include 255 different layout features, but
+ popular layout features are predefined (see
+ http://developer.apple.com/fonts/Registry/index.html). Some fonts
+ include feature numbers which are incompatible with the predefined
+ feature registry.
+
+ In our survey, there are 140 fonts including `feat' table.
+
+ a) 67 fonts use a feature number which should not be used.
+ b) 117 fonts set the wrong feature range (nSetting). This is mostly
+ found in the `mort' and `morx' tables.
+
+ Apple font tools give no warning, although they cannot recognize
+ what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but
+ continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns
+ and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID,
+ gxvalid warns and aborts in both cases (a, b).
+
+ 4-6. invalid prop version (10/183)
+ ----------------------------------
+
+ As most TrueType GX tables, the `prop' table must start with a 32bit
+ version identifier: 0x00010000, 0x00020000 or 0x00030000. But some
+ fonts store nonsense binary data instead. When Apple font tools
+ find them, they abort the processing immediately, and the data which
+ follows is unhandled. gxvalid does the same.
+
+ 10 fonts include broken `prop' version.
+
+ All of these fonts are classic TrueType fonts for the Japanese
+ script, manufactured by Apple.
+
+ 4-7. unknown resource name (2/183)
+ ------------------------------------
+
+ NOTE: THIS IS NOT A TRUETYPE GX ERROR.
+
+ If a TrueType font is stored in the resource fork or in dfont
+ format, the data must be tagged as `sfnt' in the resource fork index
+ to invoke TrueType font handler for the data. But the TrueType font
+ data in `Keyboard.dfont' is tagged as `kbd', and that in
+ `LastResort.dfont' is tagged as `lst'. Apple font tools can detect
+ that the data is in TrueType format and successfully validate them.
+ Maybe this is possible because they are known to be dfont. The
+ current implementation of the resource fork driver of FreeType
+ cannot do that, thus gxvalid cannot validate them.
+
+ 2 fonts use an unknown tag for the TrueType font resource.
+
+5. `kern' table issues
+----------------------
+
+ In common terminology of TrueType, `kern' is classified as a basic and
+ platform-independent table. But there are Apple extensions of `kern',
+ and there is an extension which requires a GX state machine for
+ contextual kerning. Therefore, gxvalid includes a special validator
+ for `kern' tables. Unfortunately, there is no exact algorithm to
+ check Apple's extension, so gxvalid includes a heuristic algorithm to
+ find the proper validation routines for all possible data formats,
+ including the data format for Microsoft. By calling
+ classic_kern_validate() instead of gxv_validate(), you can specify the
+ `kern' format explicitly. However, current FreeType2 uses Microsoft
+ `kern' format only, others are ignored (and should be handled in a
+ library one level higher than FreeType).
+
+ 5-1. History
+ ------------
+
+ The original 16bit version of `kern' was designed by Apple in the
+ pre-GX era, and it was also approved by Microsoft. Afterwards,
+ Apple designed a new 32bit version of the `kern' table. According
+ to the documentation, the difference between the 16bit and 32bit
+ version is only the size of variables in the `kern' header. In the
+ following, we call the original 16bit version as `classic', and
+ 32bit version as `new'.
+
+ 5-2. Versions and dialects which should be differentiated
+ ---------------------------------------------------------
+
+ The `kern' table consists of a table header and several subtables.
+ The version number which identifies a `classic' or a `new' version
+ is explicitly written in the table header, but there are
+ undocumented differences between Microsoft's and Apple's formats.
+ It is called a `dialect' in the following. There are three cases
+ which should be handled: the new Apple-dialect, the classic
+ Apple-dialect, and the classic Microsoft-dialect. An analysis of
+ the formats and the auto detection algorithm of gxvalid is described
+ in the following.
+
+ 5-2-1. Version detection: classic and new kern
+ ----------------------------------------------
+
+ According to Apple TrueType specification, there are only two
+ differences between the classic and the new:
+
+ - The `kern' table header starts with the version number.
+ The classic version starts with 0x0000 (16bit),
+ the new version starts with 0x00010000 (32bit).
+
+ - In the `kern' table header, the number of subtables follows
+ the version number.
+ In the classic version, it is stored as a 16bit value.
+ In the new version, it is stored as a 32bit value.
+
+ From Apple font tool's output (DumpKERN is also tested in addition
+ to the three Apple font tools in above), there is another
+ undocumented difference. In the new version, the subtable header
+ includes a 16bit variable named `tupleIndex' which does not exist
+ in the classic version.
+
+ The new version can store all subtable formats (0, 1, 2, and 3),
+ but the Apple TrueType specification does not mention the subtable
+ formats available in the classic version.
+
+ 5-2-2. Available subtable formats in classic version
+ ----------------------------------------------------
+
+ Although the Apple TrueType specification recommends to use the
+ classic version in the case if the font is designed for both the
+ Apple and Microsoft platforms, it does not document the available
+ subtable formats in the classic version.
+
+ According to the Microsoft TrueType specification, the subtable
+ format assured for Windows and OS/2 support is only subtable
+ format 0. The Microsoft TrueType specification also describes
+ subtable format 2, but does not mention which platforms support
+ it. Aubtable formats 1, 3, and higher are documented as reserved
+ for future use. Therefore, the classic version can store subtable
+ formats 0 and 2, at least. `ttfdump.exe', a font tool provided by
+ Microsoft, ignores the subtable format written in the subtable
+ header, and parses the table as if all subtables are in format 0.
+
+ `kern' subtable format 1 uses a StateTable, so it cannot be
+ utilized without a GX State Machine. Therefore, it is reasonable
+ to assume that format 1 (and 3) were introduced after Apple had
+ introduced GX and moved to the new 32bit version.
+
+ 5-2-3. Apple and Microsoft dialects
+ -----------------------------------
+
+ The `kern' subtable has a 16bit `coverage' field to describe
+ kerning attributes, but bit interpretations by Apple and Microsoft
+ are different: For example, Apple uses bits 0-7 to identify the
+ subtable, while Microsoft uses bits 8-15.
+
+ In addition, due to the output of DumpKERN and FontValidator,
+ Apple's bit interpretations of coverage in classic and new version
+ are incompatible also. In summary, there are three dialects:
+ classic Apple dialect, classic Microsoft dialect, and new Apple
+ dialect. The classic Microsoft dialect and the new Apple dialect
+ are documented by each vendors' TrueType font specification, but
+ the documentation for classic Apple dialect is not available.
+
+ For example, in the new Apple dialect, bit 15 is documented as
+ `set to 1 if the kerning is vertical'. On the other hand, in
+ classic Microsoft dialect, bit 1 is documented as `set to 1 if the
+ kerning is horizontal'. From the outputs of DumpKERN and
+ FontValidator, classic Apple dialect recognizes 15 as `set to 1
+ when the kerning is horizontal'. From the results of similar
+ experiments, classic Apple dialect seems to be the Endian reverse
+ of the classic Microsoft dialect.
+
+ As a conclusion it must be noted that no font tool can identify
+ classic Apple dialect or classic Microsoft dialect automatically.
+
+ 5-2-4. gxvalid auto dialect detection algorithm
+ -----------------------------------------------
+
+ The first 16 bits of the `kern' table are enough to identify the
+ version:
+
+ - if the first 16 bits are 0x0000, the `kern' table is in
+ classic Apple dialect or classic Microsoft dialect
+ - if the first 16 bits are 0x0001, and next 16 bits are 0x0000,
+ the kern table is in new Apple dialect.
+
+ If the `kern' table is a classic one, the 16bit `coverage' field
+ is checked next. Firstly, the coverage bits are decoded for the
+ classic Apple dialect using the following bit masks (this is based
+ on DumpKERN output):
+
+ 0x8000: 1=horizontal, 0=vertical
+ 0x4000: not used
+ 0x2000: 1=cross-stream, 0=normal
+ 0x1FF0: reserved
+ 0x000F: subtable format
+
+ If any of reserved bits are set or the subtable bits is
+ interpreted as format 1 or 3, we take it as `impossible in classic
+ Apple dialect' and retry, using the classic Microsoft dialect.
+
+ The most popular coverage in new Apple-dialect: 0x8000,
+ The most popular coverage in classic Apple-dialect: 0x0000,
+ The most popular coverage in classic Microsoft dialect: 0x0001.
+
+ 5-3. Tested fonts
+ -----------------
+
+ We checked 59 fonts bundled with MacOS and 38 fonts bundled with
+ Windows, where all font include a `kern' table.
+
+ - fonts bundled with MacOS
+ * new Apple dialect
+ format 0: 18
+ format 2: 1
+ format 3: 1
+ * classic Apple dialect
+ format 0: 14
+ * classic Microsoft dialect
+ format 0: 15
+
+ - fonts bundled with Windows
+ * classic Microsoft dialect
+ format 0: 38
+
+ It looks strange that classic Microsoft-dialect fonts are bundled to
+ MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.
+
+
+ ACKNOWLEDGEMENT
+ ---------------
+
+ Some parts of gxvalid are derived from both the `gxlayout' module and
+ the `otvalid' module. Development of gxlayout was supported by the
+ Information-technology Promotion Agency(IPA), Japan.
+
+ The detailed analysis of undefined glyph ID utilization in `mort' and
+ `morx' tables is provided by George Williams.

+ /* */
+ /* o its scanline position boundaries, i.e. `Ymin' and `Ymax' */

+ /* o an array of intersection coordinates for each scanline */
+ /* between `Ymin' and `Ymax' */
+ /* */
+ /* o a direction, indicating whether it was built going `up' or */
+ /* `down', as this is very important for filling rules */
+ /* */
+ /* o its drop-out mode */
+ /* */
+ /* 2 - Sweeping the target map's scanlines in order to compute segment */
+ /* `spans' which are then filled. Additionally, this pass */
+ /* performs drop-out control. */
+ /* */
+ /* The outline data is parsed during step 1 only. The profiles are */
+ /* built from the bottom of the render pool, used as a stack. The */
+ /* following graphics shows the profile list under construction: */
+ /* */
+ /* __________________________________________________________ _ _ */
+ /* | | | | | */
+ /* | profile | coordinates for | profile | coordinates for |--> */
+ /* | 1 | profile 1 | 2 | profile 2 |--> */
+ /* |_________|_________________|_________|_________________|__ _ _ */
+ /* */
+ /* ^ ^ */
+ /* | | */
+ /* start of render pool top */
+ /* */
+ /* The top of the profile stack is kept in the `top' variable. */
+ /* */
+ /* As you can see, a profile record is pushed on top of the render */
+ /* pool, which is then followed by its coordinates/intersections. If */
+ /* a change of direction is detected in the outline, a new profile is */
+ /* generated until the end of the outline. */
+ /* */
+ /* Note that when all profiles have been generated, the function */
+ /* Finalize_Profile_Table() is used to record, for each profile, its */
+ /* bottom-most scanline as well as the scanline above its upmost */
+ /* boundary. These positions are called `y-turns' because they (sort */
+ /* of) correspond to local extrema. They are stored in a sorted list */
+ /* built from the top of the render pool as a downwards stack: */
+ /* */
+ /* _ _ _______________________________________ */
+ /* | | */
+ /* <--| sorted list of | */
+ /* <--| extrema scanlines | */
+ /* _ _ __________________|____________________| */
+ /* */
+ /* ^ ^ */
+ /* | | */
+ /* maxBuff sizeBuff = end of pool */
+ /* */
+ /* This list is later used during the sweep phase in order to */
+ /* optimize performance (see technical note on the sweep below). */

+ * rsb = aw - (lsb + xmax - xmin)
+ *
+ * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
+ * and `xmax' the glyph's minimum and maximum x value), the OpenType
+ * specification defines the initial position of horizontal phantom points
+ * as
+ *
+ * pp1 = (round(xmin - lsb), 0) ,
+ * pp2 = (round(pp1 + aw), 0) .
+ *
+ * Note that the rounding to the grid (in the device space) is not
+ * documented currently in the specification.
+ *
+ * However, the specification lacks the precise definition of vertical
+ * phantom points. Greg Hitchcock provided the following explanation.
+ *
+ * - a `vmtx' table is present
+ *
+ * For any glyph, the minimum and maximum y values (`ymin' and `ymax')
+ * are given in the `glyf' table, the top side bearing (tsb) and advance
+ * height (ah) are given in the `vmtx' table. The bottom side bearing
+ * (bsb) is then calculated as
+ *
+ * bsb = ah - (tsb + ymax - ymin) ,
+ *
+ * and the initial position of vertical phantom points is
+ *
+ * pp3 = (x, round(ymax + tsb)) ,
+ * pp4 = (x, round(pp3 - ah)) .
+ *
+ * See below for value `x'.
+ *
+ * - no `vmtx' table in the font
+ *
+ * If there is an `OS/2' table, we set
+ *
+ * DefaultAscender = sTypoAscender ,
+ * DefaultDescender = sTypoDescender ,
+ *
+ * otherwise we use data from the `hhea' table:
+ *
+ * DefaultAscender = Ascender ,
+ * DefaultDescender = Descender .
+ *
+ * With these two variables we can now set
+ *
+ * ah = DefaultAscender - sDefaultDescender ,
+ * tsb = DefaultAscender - yMax ,
+ *
+ * and proceed as if a `vmtx' table was present.
+ *
+ * Usually we have
+ *
+ * x = aw / 2 , (1)
+ *
+ * but there is one compatibility case where it can be set to
+ *
+ * x = -DefaultDescender -
+ * ((DefaultAscender - DefaultDescender - aw) / 2) . (2)
+ *
+ * and another one with
+ *
+ * x = 0 . (3)
+ *
+ * In Windows, the history of those values is quite complicated,
+ * depending on the hinting engine (that is, the graphics framework).

+ /*
+ * Modern TrueType fonts are usually rendered through Microsoft's
+ * collection of rendering techniques called ClearType (e.g., subpixel
+ * rendering and subpixel hinting). When ClearType was introduced, most
+ * fonts were not ready. Microsoft decided to implement a backwards
+ * compatibility mode that employed several simple to complicated
+ * assumptions and tricks that modified the interpretation of the
+ * bytecode contained in these fonts to make them look ClearType-y
+ * somehow. Most (web)fonts that were released since then have come to
+ * rely on these hacks to render correctly, even some of Microsoft's
+ * flagship ClearType fonts (Calibri, Cambria, Segoe UI).
+ *
+ * The minimal subpixel hinting code (interpreter version 40) employs a
+ * small list of font-agnostic hacks to bludgeon non-native-ClearType
+ * fonts (except tricky ones[1]) into submission. It will not try to
+ * toggle hacks for specific fonts for performance and complexity
+ * reasons. The focus is on modern (web)fonts rather than legacy fonts
+ * that were made for black-and-white rendering.
+ *
+ * Major hacks
+ *
+ * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+ * `Direct_Move_X'). This has the smallest code footprint and single
+ * biggest effect. The ClearType way to increase resolution is
+ * supersampling the x axis, the FreeType way is ignoring instructions
+ * on the x axis, which gives the same result in the majority of
+ * cases.
+ *
+ * - Points are not moved post-IUP (neither on the x nor on the y axis),
+ * except the x component of diagonal moves post-IUP (cf.
+ * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
+ * changes are commonly used to `fix' pixel patterns which has little
+ * use outside monochrome rendering.
+ *
+ * - SHPIX and DELTAP don't execute unless moving a composite on the
+ * y axis or moving a previously y touched point. SHPIX additionally
+ * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+ * Both instructions are commonly used to `fix' pixel patterns for
+ * monochrome or Windows's GDI rendering but make little sense for
+ * FreeType rendering. Both can distort the outline. See [2] for
+ * details.
+ *
+ * - The hdmx table and modifications to phantom points are ignored.
+ * Bearings and advance widths remain unchanged (except rounding them
+ * outside the interpreter!), cf. `compute_glyph_metrics' and
+ * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
+ * might mess up spacing.
+ *
+ * Minor hacks
+ *
+ * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
+ * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+ * various sizes.
+ *
+ * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+ * executed.)
+ *
+ * The best results are achieved for fonts that were from the outset
+ * designed with ClearType in mind, meaning they leave the x axis mostly
+ * alone and don't mess with the `final' outline to produce more
+ * pleasing pixel patterns. The harder the designer tried to produce
+ * very specific patterns (`superhinting') for pre-ClearType-displays,
+ * the worse the results.
+ *
+ * Microsoft defines a way to turn off backwards compatibility and
+ * interpret instructions as before (called `native ClearType')[2][3].
+ * The font designer then regains full control and is responsible for
+ * making the font work correctly with ClearType without any
+ * hand-holding by the interpreter or rasterizer[4]. The v40
+ * interpreter assumes backwards compatibility by default, which can be
+ * turned off the same way by executing the following in the control
+ * program (cf. `Ins_INSTCTRL').
+ *
+ * #PUSH 4,3
+ * INSTCTRL[]
+ *
+ * [1] Tricky fonts as FreeType defines them rely on the bytecode
+ * interpreter to display correctly. Hacks can interfere with them,
+ * so they get treated like native ClearType fonts (v40 with
+ * backwards compatibility turned off). Cf. `TT_RunIns'.
+ *
+ * [2] Proposed by Microsoft's Greg Hitchcock in
+ * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+ *
+ * [3] Beat Stamm describes it in more detail:
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
+ *
+ * [4] The list of `native ClearType' fonts is small at the time of this
+ * writing; I found the following on a Windows 10 Update 1511
+ * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
+ * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
+ * SimSun, NSimSun, and Yu Gothic.
