+   *
+   * Define `TT_CONFIG_OPTION_SUBPIXEL_HINTING` if you want to compile
+   * subpixel hinting support into the TrueType driver.  This modifies the
+   * TrueType hinting mechanism when anything but `FT_RENDER_MODE_MONO` is
+   * requested.
+   *
+   * In particular, it modifies the bytecode interpreter to interpret (or
+   * not) instructions in a certain way so that all TrueType fonts look like
+   * they do in a Windows ClearType (DirectWrite) environment.  See [1] for a
+   * technical overview on what this means.  See `ttinterp.h` for more
+   * details on the LEAN option.
+   *
+   * There are three possible values.
+   *
+   * Value 1:
+   *   This value is associated with the 'Infinality' moniker, contributed by
+   *   an individual nicknamed Infinality with the goal of making TrueType
+   *   fonts render better than on Windows.  A high amount of configurability
+   *   and flexibility, down to rules for single glyphs in fonts, but also
+   *   very slow.  Its experimental and slow nature and the original
+   *   developer losing interest meant that this option was never enabled in
+   *   default builds.
+   *
+   *   The corresponding interpreter version is v38.
+   *
+   * Value 2:
+   *   The new default mode for the TrueType driver.  The Infinality code
+   *   base was stripped to the bare minimum and all configurability removed
+   *   in the name of speed and simplicity.  The configurability was mainly
+   *   aimed at legacy fonts like 'Arial', 'Times New Roman', or 'Courier'.
+   *   Legacy fonts are fonts that modify vertical stems to achieve clean
+   *   black-and-white bitmaps.  The new mode focuses on applying a minimal
+   *   set of rules to all fonts indiscriminately so that modern and web
+   *   fonts render well while legacy fonts render okay.
+   *
+   *   The corresponding interpreter version is v40.
+   *
+   * Value 3:
+   *   Compile both, making both v38 and v40 available (the latter is the
+   *   default).
+   *
+   * By undefining these, you get rendering behavior like on Windows without
+   * ClearType, i.e., Windows XP without ClearType enabled and Win9x
+   * (interpreter version v35).  Or not, depending on how much hinting blood
+   * and testing tears the font designer put into a given font.  If you
+   * define one or both subpixel hinting options, you can switch between
+   * between v35 and the ones you define (using `FT_Property_Set`).
+   *
+   * This option requires `TT_CONFIG_OPTION_BYTECODE_INTERPRETER` to be
+   * defined.

+   * @enum:
+   *   FT_Encoding
+   *
+   * @description:
+   *   An enumeration to specify character sets supported by charmaps.  Used
+   *   in the @FT_Select_Charmap API function.
+   *
+   * @note:
+   *   Despite the name, this enumeration lists specific character
+   *   repertories (i.e., charsets), and not text encoding methods (e.g.,
+   *   UTF-8, UTF-16, etc.).
+   *
+   *   Other encodings might be defined in the future.
+   *
+   * @values:
+   *   FT_ENCODING_NONE ::
+   *     The encoding value~0 is reserved for all formats except BDF, PCF,
+   *     and Windows FNT; see below for more information.
+   *
+   *   FT_ENCODING_UNICODE ::
+   *     The Unicode character set.  This value covers all versions of the
+   *     Unicode repertoire, including ASCII and Latin-1.  Most fonts include
+   *     a Unicode charmap, but not all of them.
+   *
+   *     For example, if you want to access Unicode value U+1F028 (and the
+   *     font contains it), use value 0x1F028 as the input value for
+   *     @FT_Get_Char_Index.
+   *
+   *   FT_ENCODING_MS_SYMBOL ::
+   *     Microsoft Symbol encoding, used to encode mathematical symbols and
+   *     wingdings.  For more information, see
+   *     'https://www.microsoft.com/typography/otspec/recom.htm',
+   *     'http://www.kostis.net/charsets/symbol.htm', and
+   *     'http://www.kostis.net/charsets/wingding.htm'.
+   *
+   *     This encoding uses character codes from the PUA (Private Unicode
+   *     Area) in the range U+F020-U+F0FF.
+   *
+   *   FT_ENCODING_SJIS ::
+   *     Shift JIS encoding for Japanese.  More info at
+   *     'https://en.wikipedia.org/wiki/Shift_JIS'.  See note on multi-byte
+   *     encodings below.
+   *
+   *   FT_ENCODING_PRC ::
+   *     Corresponds to encoding systems mainly for Simplified Chinese as
+   *     used in People's Republic of China (PRC).  The encoding layout is
+   *     based on GB~2312 and its supersets GBK and GB~18030.
+   *
+   *   FT_ENCODING_BIG5 ::
+   *     Corresponds to an encoding system for Traditional Chinese as used in
+   *     Taiwan and Hong Kong.
+   *
+   *   FT_ENCODING_WANSUNG ::
+   *     Corresponds to the Korean encoding system known as Extended Wansung
+   *     (MS Windows code page 949).  For more information see
+   *     'https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit949.txt'.
+   *
+   *   FT_ENCODING_JOHAB ::
+   *     The Korean standard character set (KS~C 5601-1992), which
+   *     corresponds to MS Windows code page 1361.  This character set
+   *     includes all possible Hangul character combinations.
+   *
+   *   FT_ENCODING_ADOBE_LATIN_1 ::
+   *     Corresponds to a Latin-1 encoding as defined in a Type~1 PostScript
+   *     font.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_STANDARD ::
+   *     Adobe Standard encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_EXPERT ::
+   *     Adobe Expert encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_CUSTOM ::
+   *     Corresponds to a custom encoding, as found in Type~1, CFF, and
+   *     OpenType/CFF fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_APPLE_ROMAN ::
+   *     Apple roman encoding.  Many TrueType and OpenType fonts contain a
+   *     charmap for this 8-bit encoding, since older versions of Mac OS are
+   *     able to use it.
+   *
+   *   FT_ENCODING_OLD_LATIN_2 ::
+   *     This value is deprecated and was neither used nor reported by
+   *     FreeType.  Don't use or test for it.
+   *
+   *   FT_ENCODING_MS_SJIS ::
+   *     Same as FT_ENCODING_SJIS.  Deprecated.
+   *
+   *   FT_ENCODING_MS_GB2312 ::
+   *     Same as FT_ENCODING_PRC.  Deprecated.

+   *   FT_ENCODING_MS_JOHAB ::
+   *     Same as FT_ENCODING_JOHAB.  Deprecated.
+   *
+   * @note:
+   *   By default, FreeType enables a Unicode charmap and tags it with
+   *   `FT_ENCODING_UNICODE` when it is either provided or can be generated
+   *   from PostScript glyph name dictionaries in the font file.  All other
+   *   encodings are considered legacy and tagged only if explicitly defined
+   *   in the font file.  Otherwise, `FT_ENCODING_NONE` is used.
+   *
+   *   `FT_ENCODING_NONE` is set by the BDF and PCF drivers if the charmap is
+   *   neither Unicode nor ISO-8859-1 (otherwise it is set to
+   *   `FT_ENCODING_UNICODE`).  Use @FT_Get_BDF_Charset_ID to find out which
+   *   encoding is really present.  If, for example, the `cs_registry` field
+   *   is 'KOI8' and the `cs_encoding` field is 'R', the font is encoded in
+   *   KOI8-R.
+   *
+   *   `FT_ENCODING_NONE` is always set (with a single exception) by the
+   *   winfonts driver.  Use @FT_Get_WinFNT_Header and examine the `charset`
+   *   field of the @FT_WinFNT_HeaderRec structure to find out which encoding
+   *   is really present.  For example, @FT_WinFNT_ID_CP1251 (204) means
+   *   Windows code page 1251 (for Russian).
+   *
+   *   `FT_ENCODING_NONE` is set if `platform_id` is @TT_PLATFORM_MACINTOSH
+   *   and `encoding_id` is not `TT_MAC_ID_ROMAN` (otherwise it is set to

+   * @struct:
+   *   FT_FaceRec
+   *
+   * @description:
+   *   FreeType root face class structure.  A face object models a typeface
+   *   in a font file.
+   *
+   * @fields:
+   *   num_faces ::
+   *     The number of faces in the font file.  Some font formats can have
+   *     multiple faces in a single font file.
+   *
+   *   face_index ::
+   *     This field holds two different values.  Bits 0-15 are the index of
+   *     the face in the font file (starting with value~0).  They are set
+   *     to~0 if there is only one face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation
+   *     fonts only, holding the named instance index for the current face
+   *     index (starting with value~1; value~0 indicates font access without
+   *     a named instance).  For non-variation fonts, bits 16-30 are ignored.
+   *     If we have the third named instance of face~4, say, `face_index` is
+   *     set to 0x00030004.
+   *
+   *     Bit 31 is always zero (this is, `face_index` is always a positive
+   *     value).
+   *
+   *     [Since 2.9] Changing the design coordinates with
+   *     @FT_Set_Var_Design_Coordinates or @FT_Set_Var_Blend_Coordinates does
+   *     not influence the named instance index value (only
+   *     @FT_Set_Named_Instance does that).
+   *
+   *   face_flags ::
+   *     A set of bit flags that give important information about the face;
+   *     see @FT_FACE_FLAG_XXX for the details.
+   *
+   *   style_flags ::
+   *     The lower 16~bits contain a set of bit flags indicating the style of
+   *     the face; see @FT_STYLE_FLAG_XXX for the details.
+   *
+   *     [Since 2.6.1] Bits 16-30 hold the number of named instances
+   *     available for the current face if we have a GX or OpenType variation
+   *     (sub)font.  Bit 31 is always zero (this is, `style_flags` is always
+   *     a positive value).  Note that a variation font has always at least
+   *     one named instance, namely the default instance.
+   *
+   *   num_glyphs ::
+   *     The number of glyphs in the face.  If the face is scalable and has
+   *     sbits (see `num_fixed_sizes`), it is set to the number of outline
+   *     glyphs.
+   *
+   *     For CID-keyed fonts (not in an SFNT wrapper) this value gives the
+   *     highest CID used in the font.
+   *
+   *   family_name ::
+   *     The face's family name.  This is an ASCII string, usually in
+   *     English, that describes the typeface's family (like 'Times New
+   *     Roman', 'Bodoni', 'Garamond', etc).  This is a least common
+   *     denominator used to list fonts.  Some formats (TrueType & OpenType)
+   *     provide localized and Unicode versions of this string.  Applications
+   *     should use the format-specific interface to access them.  Can be
+   *     `NULL` (e.g., in fonts embedded in a PDF file).
+   *
+   *     In case the font doesn't provide a specific family name entry,
+   *     FreeType tries to synthesize one, deriving it from other name
+   *     entries.
+   *
+   *   style_name ::
+   *     The face's style name.  This is an ASCII string, usually in English,
+   *     that describes the typeface's style (like 'Italic', 'Bold',
+   *     'Condensed', etc).  Not all font formats provide a style name, so
+   *     this field is optional, and can be set to `NULL`.  As for
+   *     `family_name`, some formats provide localized and Unicode versions
+   *     of this string.  Applications should use the format-specific
+   *     interface to access them.
+   *
+   *   num_fixed_sizes ::
+   *     The number of bitmap strikes in the face.  Even if the face is
+   *     scalable, there might still be bitmap strikes, which are called
+   *     'sbits' in that case.
+   *
+   *   available_sizes ::
+   *     An array of @FT_Bitmap_Size for all bitmap strikes in the face.  It
+   *     is set to `NULL` if there is no bitmap strike.
+   *
+   *     Note that FreeType tries to sanitize the strike data since they are
+   *     sometimes sloppy or incorrect, but this can easily fail.
+   *
+   *   num_charmaps ::
+   *     The number of charmaps in the face.
+   *
+   *   charmaps ::
+   *     An array of the charmaps of the face.
+   *
+   *   generic ::
+   *     A field reserved for client uses.  See the @FT_Generic type
+   *     description.
+   *
+   *   bbox ::
+   *     The font bounding box.  Coordinates are expressed in font units (see
+   *     `units_per_EM`).  The box is large enough to contain any glyph from
+   *     the font.  Thus, `bbox.yMax` can be seen as the 'maximum ascender',
+   *     and `bbox.yMin` as the 'minimum descender'.  Only relevant for
+   *     scalable formats.
+   *
+   *     Note that the bounding box might be off by (at least) one pixel for
+   *     hinted fonts.  See @FT_Size_Metrics for further discussion.
+   *
+   *   units_per_EM ::
+   *     The number of font units per EM square for this face.  This is
+   *     typically 2048 for TrueType fonts, and 1000 for Type~1 fonts.  Only
+   *     relevant for scalable formats.
+   *
+   *   ascender ::
+   *     The typographic ascender of the face, expressed in font units.  For
+   *     font formats not having this information, it is set to `bbox.yMax`.
+   *     Only relevant for scalable formats.
+   *
+   *   descender ::
+   *     The typographic descender of the face, expressed in font units.  For
+   *     font formats not having this information, it is set to `bbox.yMin`.
+   *     Note that this field is negative for values below the baseline.
+   *     Only relevant for scalable formats.
+   *
+   *   height ::
+   *     This value is the vertical distance between two consecutive
+   *     baselines, expressed in font units.  It is always positive.  Only
+   *     relevant for scalable formats.
+   *
+   *     If you want the global glyph height, use `ascender - descender`.
+   *
+   *   max_advance_width ::
+   *     The maximum advance width, in font units, for all glyphs in this
+   *     face.  This can be used to make word wrapping computations faster.
+   *     Only relevant for scalable formats.
+   *
+   *   max_advance_height ::
+   *     The maximum advance height, in font units, for all glyphs in this
+   *     face.  This is only relevant for vertical layouts, and is set to
+   *     `height` for fonts that do not provide vertical metrics.  Only
+   *     relevant for scalable formats.
+   *
+   *   underline_position ::
+   *     The position, in font units, of the underline line for this face.
+   *     It is the center of the underlining stem.  Only relevant for
+   *     scalable formats.
+   *
+   *   underline_thickness ::
+   *     The thickness, in font units, of the underline for this face.  Only
+   *     relevant for scalable formats.
+   *
+   *   glyph ::
+   *     The face's associated glyph slot(s).
+   *
+   *   size ::
+   *     The current active size for this face.
+   *
+   *   charmap ::
+   *     The current active charmap for this face.
+   *
+   * @note:
+   *   Fields may be changed after a call to @FT_Attach_File or
+   *   @FT_Attach_Stream.
+   *
+   *   For an OpenType variation font, the values of the following fields can
+   *   change after a call to @FT_Set_Var_Design_Coordinates (and friends) if
+   *   the font contains an 'MVAR' table: `ascender`, `descender`, `height`,
+   *   `underline_position`, and `underline_thickness`.
+   *
+   *   Especially for TrueType fonts see also the documentation for
+   *   @FT_Size_Metrics.

+   *   FT_FACE_FLAG_XXX
+   *
+   * @description:
+   *   A list of bit flags used in the `face_flags` field of the @FT_FaceRec
+   *   structure.  They inform client applications of properties of the
+   *   corresponding face.
+   *
+   * @values:
+   *   FT_FACE_FLAG_SCALABLE ::
+   *     The face contains outline glyphs.  Note that a face can contain
+   *     bitmap strikes also, i.e., a face can have both this flag and
+   *     @FT_FACE_FLAG_FIXED_SIZES set.
+   *
+   *   FT_FACE_FLAG_FIXED_SIZES ::
+   *     The face contains bitmap strikes.  See also the `num_fixed_sizes`
+   *     and `available_sizes` fields of @FT_FaceRec.
+   *
+   *   FT_FACE_FLAG_FIXED_WIDTH ::
+   *     The face contains fixed-width characters (like Courier, Lucida,
+   *     MonoType, etc.).
+   *
+   *   FT_FACE_FLAG_SFNT ::
+   *     The face uses the SFNT storage scheme.  For now, this means TrueType
+   *     and OpenType.
+   *
+   *   FT_FACE_FLAG_HORIZONTAL ::
+   *     The face contains horizontal glyph metrics.  This should be set for
+   *     all common formats.
+   *
+   *   FT_FACE_FLAG_VERTICAL ::
+   *     The face contains vertical glyph metrics.  This is only available in
+   *     some formats, not all of them.
+   *
+   *   FT_FACE_FLAG_KERNING ::
+   *     The face contains kerning information.  If set, the kerning distance
+   *     can be retrieved using the function @FT_Get_Kerning.  Otherwise the
+   *     function always return the vector (0,0).  Note that FreeType doesn't
+   *     handle kerning data from the SFNT 'GPOS' table (as present in many
+   *     OpenType fonts).
+   *
+   *   FT_FACE_FLAG_FAST_GLYPHS ::
+   *     THIS FLAG IS DEPRECATED.  DO NOT USE OR TEST IT.
+   *
+   *   FT_FACE_FLAG_MULTIPLE_MASTERS ::
+   *     The face contains multiple masters and is capable of interpolating
+   *     between them.  Supported formats are Adobe MM, TrueType GX, and
+   *     OpenType variation fonts.
+   *
+   *     See section @multiple_masters for API details.
+   *
+   *   FT_FACE_FLAG_GLYPH_NAMES ::
+   *     The face contains glyph names, which can be retrieved using
+   *     @FT_Get_Glyph_Name.  Note that some TrueType fonts contain broken
+   *     glyph name tables.  Use the function @FT_Has_PS_Glyph_Names when
+   *     needed.
+   *
+   *   FT_FACE_FLAG_EXTERNAL_STREAM ::
+   *     Used internally by FreeType to indicate that a face's stream was
+   *     provided by the client application and should not be destroyed when
+   *     @FT_Done_Face is called.  Don't read or test this flag.
+   *
+   *   FT_FACE_FLAG_HINTER ::
+   *     The font driver has a hinting machine of its own.  For example, with
+   *     TrueType fonts, it makes sense to use data from the SFNT 'gasp'
+   *     table only if the native TrueType hinting engine (with the bytecode
+   *     interpreter) is available and active.
+   *
+   *   FT_FACE_FLAG_CID_KEYED ::
+   *     The face is CID-keyed.  In that case, the face is not accessed by
+   *     glyph indices but by CID values.  For subsetted CID-keyed fonts this
+   *     has the consequence that not all index values are a valid argument
+   *     to @FT_Load_Glyph.  Only the CID values for which corresponding
+   *     glyphs in the subsetted font exist make `FT_Load_Glyph` return
+   *     successfully; in all other cases you get an
+   *     `FT_Err_Invalid_Argument` error.
+   *
+   *     Note that CID-keyed fonts that are in an SFNT wrapper (this is, all
+   *     OpenType/CFF fonts) don't have this flag set since the glyphs are
+   *     accessed in the normal way (using contiguous indices); the
+   *     'CID-ness' isn't visible to the application.
+   *
+   *   FT_FACE_FLAG_TRICKY ::
+   *     The face is 'tricky', this is, it always needs the font format's
+   *     native hinting engine to get a reasonable result.  A typical example
+   *     is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that
+   *     uses TrueType bytecode instructions to move and scale all of its
+   *     subglyphs.
+   *
+   *     It is not possible to auto-hint such fonts using
+   *     @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING.
+   *     You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to

+   *
+   *   FT_FACE_FLAG_COLOR ::
+   *     [Since 2.5.1] The face has color glyph tables.  See @FT_LOAD_COLOR
+   *     for more information.
+   *
+   *   FT_FACE_FLAG_VARIATION ::
+   *     [Since 2.9] Set if the current face (or named instance) has been
+   *     altered with @FT_Set_MM_Design_Coordinates,
+   *     @FT_Set_Var_Design_Coordinates, or @FT_Set_Var_Blend_Coordinates.

+   *   FT_Size_Metrics
+   *
+   * @description:
+   *   The size metrics structure gives the metrics of a size object.
+   *
+   * @fields:
+   *   x_ppem ::
+   *     The width of the scaled EM square in pixels, hence the term 'ppem'
+   *     (pixels per EM).  It is also referred to as 'nominal width'.
+   *
+   *   y_ppem ::
+   *     The height of the scaled EM square in pixels, hence the term 'ppem'
+   *     (pixels per EM).  It is also referred to as 'nominal height'.
+   *
+   *   x_scale ::
+   *     A 16.16 fractional scaling value to convert horizontal metrics from
+   *     font units to 26.6 fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   y_scale ::
+   *     A 16.16 fractional scaling value to convert vertical metrics from
+   *     font units to 26.6 fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   ascender ::
+   *     The ascender in 26.6 fractional pixels, rounded up to an integer
+   *     value.  See @FT_FaceRec for the details.
+   *
+   *   descender ::
+   *     The descender in 26.6 fractional pixels, rounded down to an integer
+   *     value.  See @FT_FaceRec for the details.
+   *
+   *   height ::
+   *     The height in 26.6 fractional pixels, rounded to an integer value.
+   *     See @FT_FaceRec for the details.
+   *
+   *   max_advance ::
+   *     The maximum advance width in 26.6 fractional pixels, rounded to an
+   *     integer value.  See @FT_FaceRec for the details.
+   *
+   * @note:
+   *   The scaling values, if relevant, are determined first during a size
+   *   changing operation.  The remaining fields are then set by the driver.
+   *   For scalable formats, they are usually set to scaled values of the
+   *   corresponding fields in @FT_FaceRec.  Some values like ascender or
+   *   descender are rounded for historical reasons; more precise values (for
+   *   outline fonts) can be derived by scaling the corresponding @FT_FaceRec
+   *   values manually, with code similar to the following.
+   *
+   *   ```
+   *     scaled_ascender = FT_MulFix( face->ascender,
+   *                                  size_metrics->y_scale );
+   *   ```
+   *
+   *   Note that due to glyph hinting and the selected rendering mode these
+   *   values are usually not exact; consequently, they must be treated as
+   *   unreliable with an error margin of at least one pixel!
+   *
+   *   Indeed, the only way to get the exact metrics is to render _all_
+   *   glyphs.  As this would be a definite performance hit, it is up to
+   *   client applications to perform such computations.
+   *
+   *   The `FT_Size_Metrics` structure is valid for bitmap fonts also.
+   *
+   *
+   *   **TrueType fonts with native bytecode hinting**
+   *
+   *   All applications that handle TrueType fonts with native hinting must
+   *   be aware that TTFs expect different rounding of vertical font
+   *   dimensions.  The application has to cater for this, especially if it
+   *   wants to rely on a TTF's vertical data (for example, to properly align
+   *   box characters vertically).
+   *
+   *   Only the application knows _in advance_ that it is going to use native
+   *   hinting for TTFs!  FreeType, on the other hand, selects the hinting
+   *   mode not at the time of creating an @FT_Size object but much later,
+   *   namely while calling @FT_Load_Glyph.
+   *
+   *   Here is some pseudo code that illustrates a possible solution.
+   *
+   *   ```
+   *     font_format = FT_Get_Font_Format( face );
+   *
+   *     if ( !strcmp( font_format, "TrueType" ) &&
+   *          do_native_bytecode_hinting         )
+   *     {
+   *       ascender  = ROUND( FT_MulFix( face->ascender,
+   *                                     size_metrics->y_scale ) );
+   *       descender = ROUND( FT_MulFix( face->descender,
+   *                                     size_metrics->y_scale ) );
+   *     }
+   *     else
+   *     {
+   *       ascender  = size_metrics->ascender;
+   *       descender = size_metrics->descender;
+   *     }
+   *
+   *     height      = size_metrics->height;
+   *     max_advance = size_metrics->max_advance;
+   *   ```

+   * @description:
+   *   FreeType root glyph slot class structure.  A glyph slot is a container
+   *   where individual glyphs can be loaded, be they in outline or bitmap
+   *   format.
+   *
+   * @fields:
+   *   library ::
+   *     A handle to the FreeType library instance this slot belongs to.
+   *
+   *   face ::
+   *     A handle to the parent face object.
+   *
+   *   next ::
+   *     In some cases (like some font tools), several glyph slots per face
+   *     object can be a good thing.  As this is rare, the glyph slots are
+   *     listed through a direct, single-linked list using its `next` field.
+   *
+   *   glyph_index ::
+   *     [Since 2.10] The glyph index passed as an argument to @FT_Load_Glyph
+   *     while initializing the glyph slot.
+   *
+   *   generic ::
+   *     A typeless pointer unused by the FreeType library or any of its
+   *     drivers.  It can be used by client applications to link their own
+   *     data to each glyph slot object.
+   *
+   *   metrics ::
+   *     The metrics of the last loaded glyph in the slot.  The returned
+   *     values depend on the last load flags (see the @FT_Load_Glyph API
+   *     function) and can be expressed either in 26.6 fractional pixels or
+   *     font units.
+   *
+   *     Note that even when the glyph image is transformed, the metrics are
+   *     not.

+   *   linearHoriAdvance ::
+   *     The advance width of the unhinted glyph.  Its value is expressed in
+   *     16.16 fractional pixels, unless @FT_LOAD_LINEAR_DESIGN is set when
+   *     loading the glyph.  This field can be important to perform correct
+   *     WYSIWYG layout.  Only relevant for outline glyphs.
+   *
+   *   linearVertAdvance ::
+   *     The advance height of the unhinted glyph.  Its value is expressed in
+   *     16.16 fractional pixels, unless @FT_LOAD_LINEAR_DESIGN is set when
+   *     loading the glyph.  This field can be important to perform correct
+   *     WYSIWYG layout.  Only relevant for outline glyphs.
+   *
+   *   advance ::
+   *     This shorthand is, depending on @FT_LOAD_IGNORE_TRANSFORM, the
+   *     transformed (hinted) advance width for the glyph, in 26.6 fractional
+   *     pixel format.  As specified with @FT_LOAD_VERTICAL_LAYOUT, it uses
+   *     either the `horiAdvance` or the `vertAdvance` value of `metrics`
+   *     field.
+   *
+   *   format ::
+   *     This field indicates the format of the image contained in the glyph
+   *     slot.  Typically @FT_GLYPH_FORMAT_BITMAP, @FT_GLYPH_FORMAT_OUTLINE,
+   *     or @FT_GLYPH_FORMAT_COMPOSITE, but other values are possible.
+   *
+   *   bitmap ::
+   *     This field is used as a bitmap descriptor.  Note that the address
+   *     and content of the bitmap buffer can change between calls of
+   *     @FT_Load_Glyph and a few other functions.
+   *
+   *   bitmap_left ::
+   *     The bitmap's left bearing expressed in integer pixels.
+   *
+   *   bitmap_top ::
+   *     The bitmap's top bearing expressed in integer pixels.  This is the
+   *     distance from the baseline to the top-most glyph scanline, upwards
+   *     y~coordinates being **positive**.
+   *
+   *   outline ::
+   *     The outline descriptor for the current glyph image if its format is
+   *     @FT_GLYPH_FORMAT_OUTLINE.  Once a glyph is loaded, `outline` can be
+   *     transformed, distorted, emboldened, etc.  However, it must not be
+   *     freed.
+   *
+   *   num_subglyphs ::
+   *     The number of subglyphs in a composite glyph.  This field is only
+   *     valid for the composite glyph format that should normally only be
+   *     loaded with the @FT_LOAD_NO_RECURSE flag.
+   *
+   *   subglyphs ::
+   *     An array of subglyph descriptors for composite glyphs.  There are
+   *     `num_subglyphs` elements in there.  Currently internal to FreeType.
+   *
+   *   control_data ::
+   *     Certain font drivers can also return the control data for a given
+   *     glyph image (e.g.  TrueType bytecode, Type~1 charstrings, etc.).
+   *     This field is a pointer to such data; it is currently internal to
+   *     FreeType.
+   *
+   *   control_len ::
+   *     This is the length in bytes of the control data.  Currently internal
+   *     to FreeType.
+   *
+   *   other ::
+   *     Reserved.
+   *
+   *   lsb_delta ::
+   *     The difference between hinted and unhinted left side bearing while
+   *     auto-hinting is active.  Zero otherwise.
+   *
+   *   rsb_delta ::
+   *     The difference between hinted and unhinted right side bearing while
+   *     auto-hinting is active.  Zero otherwise.
+   *
+   * @note:
+   *   If @FT_Load_Glyph is called with default flags (see @FT_LOAD_DEFAULT)
+   *   the glyph image is loaded in the glyph slot in its native format
+   *   (e.g., an outline glyph for TrueType and Type~1 formats).  [Since 2.9]
+   *   The prospective bitmap metrics are calculated according to
+   *   @FT_LOAD_TARGET_XXX and other flags even for the outline glyph, even
+   *   if @FT_LOAD_RENDER is not set.
+   *
+   *   This image can later be converted into a bitmap by calling
+   *   @FT_Render_Glyph.  This function searches the current renderer for the
+   *   native image's format, then invokes it.
+   *
+   *   The renderer is in charge of transforming the native image through the
+   *   slot's face transformation fields, then converting it into a bitmap
+   *   that is returned in `slot->bitmap`.
+   *
+   *   Note that `slot->bitmap_left` and `slot->bitmap_top` are also used to
+   *   specify the position of the bitmap relative to the current pen
+   *   position (e.g., coordinates (0,0) on the baseline).  Of course,
+   *   `slot->format` is also changed to @FT_GLYPH_FORMAT_BITMAP.
+   *
+   *   Here is a small pseudo code fragment that shows how to use `lsb_delta`
+   *   and `rsb_delta` to do fractional positioning of glyphs:
+   *
+   *   ```
+   *     FT_GlyphSlot  slot     = face->glyph;
+   *     FT_Pos        origin_x = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       FT_Outline_Translate( slot->outline, origin_x & 63, 0 );
+   *
+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       <compute kern between current and next glyph
+   *        and add it to `origin_x'>
+   *
+   *       origin_x += slot->advance.x;
+   *       origin_x += slot->lsb_delta - slot->rsb_delta;
+   *     endfor
+   *   ```
+   *
+   *   Here is another small pseudo code fragment that shows how to use
+   *   `lsb_delta` and `rsb_delta` to improve integer positioning of glyphs:
+   *
+   *   ```
+   *     FT_GlyphSlot  slot           = face->glyph;
+   *     FT_Pos        origin_x       = 0;
+   *     FT_Pos        prev_rsb_delta = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <compute kern between current and previous glyph
+   *        and add it to `origin_x'>
+   *
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       if ( prev_rsb_delta - slot->lsb_delta >  32 )
+   *         origin_x -= 64;
+   *       else if ( prev_rsb_delta - slot->lsb_delta < -31 )
+   *         origin_x += 64;
+   *
+   *       prev_rsb_delta = slot->rsb_delta;
+   *
+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       origin_x += slot->advance.x;
+   *     endfor
+   *   ```
+   *
+   *   If you use strong auto-hinting, you **must** apply these delta values!
+   *   Otherwise you will experience far too large inter-glyph spacing at
+   *   small rendering sizes in most cases.  Note that it doesn't harm to use
+   *   the above code for other hinting modes also, since the delta values
+   *   are zero then.

+   * @function:
+   *   FT_Open_Face
+   *
+   * @description:
+   *   Create a face object from a given resource described by @FT_Open_Args.
+   *
+   * @inout:
+   *   library ::
+   *     A handle to the library resource.
+   *
+   * @input:
+   *   args ::
+   *     A pointer to an `FT_Open_Args` structure that must be filled by the
+   *     caller.
+   *
+   *   face_index ::
+   *     This field holds two different values.  Bits 0-15 are the index of
+   *     the face in the font file (starting with value~0).  Set it to~0 if
+   *     there is only one face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation
+   *     fonts only, specifying the named instance index for the current face
+   *     index (starting with value~1; value~0 makes FreeType ignore named
+   *     instances).  For non-variation fonts, bits 16-30 are ignored.
+   *     Assuming that you want to access the third named instance in face~4,
+   *     `face_index` should be set to 0x00030004.  If you want to access
+   *     face~4 without variation handling, simply set `face_index` to
+   *     value~4.
+   *
+   *     `FT_Open_Face` and its siblings can be used to quickly check whether
+   *     the font format of a given font resource is supported by FreeType.
+   *     In general, if the `face_index` argument is negative, the function's
+   *     return value is~0 if the font format is recognized, or non-zero
+   *     otherwise.  The function allocates a more or less empty face handle
+   *     in `*aface` (if `aface` isn't `NULL`); the only two useful fields in
+   *     this special case are `face->num_faces` and `face->style_flags`.
+   *     For any negative value of `face_index`, `face->num_faces` gives the
+   *     number of faces within the font file.  For the negative value
+   *     '-(N+1)' (with 'N' a non-negative 16-bit value), bits 16-30 in
+   *     `face->style_flags` give the number of named instances in face 'N'
+   *     if we have a variation font (or zero otherwise).  After examination,
+   *     the returned @FT_Face structure should be deallocated with a call to
+   *     @FT_Done_Face.
+   *
+   * @output:
+   *   aface ::
+   *     A handle to a new face object.  If `face_index` is greater than or
+   *     equal to zero, it must be non-`NULL`.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   Unlike FreeType 1.x, this function automatically creates a glyph slot
+   *   for the face object that can be accessed directly through
+   *   `face->glyph`.
+   *
+   *   Each new face object created with this function also owns a default
+   *   @FT_Size object, accessible as `face->size`.
+   *
+   *   One @FT_Library instance can have multiple face objects, this is,
+   *   @FT_Open_Face and its siblings can be called multiple times using the
+   *   same `library` argument.
+   *
+   *   See the discussion of reference counters in the description of
+   *   @FT_Reference_Face.
+   *
+   * @example:
+   *   To loop over all faces, use code similar to the following snippet
+   *   (omitting the error handling).
+   *
+   *   ```
+   *     ...
+   *     FT_Face  face;
+   *     FT_Long  i, num_faces;
+   *
+   *
+   *     error = FT_Open_Face( library, args, -1, &face );
+   *     if ( error ) { ... }
+   *
+   *     num_faces = face->num_faces;
+   *     FT_Done_Face( face );
+   *
+   *     for ( i = 0; i < num_faces; i++ )
+   *     {
+   *       ...
+   *       error = FT_Open_Face( library, args, i, &face );
+   *       ...
+   *       FT_Done_Face( face );
+   *       ...
+   *     }
+   *   ```
+   *
+   *   To loop over all valid values for `face_index`, use something similar
+   *   to the following snippet, again without error handling.  The code
+   *   accesses all faces immediately (thus only a single call of
+   *   `FT_Open_Face` within the do-loop), with and without named instances.
+   *
+   *   ```
+   *     ...
+   *     FT_Face  face;
+   *
+   *     FT_Long  num_faces     = 0;
+   *     FT_Long  num_instances = 0;
+   *
+   *     FT_Long  face_idx     = 0;
+   *     FT_Long  instance_idx = 0;
+   *
+   *
+   *     do
+   *     {
+   *       FT_Long  id = ( instance_idx << 16 ) + face_idx;
+   *
+   *
+   *       error = FT_Open_Face( library, args, id, &face );
+   *       if ( error ) { ... }
+   *
+   *       num_faces     = face->num_faces;
+   *       num_instances = face->style_flags >> 16;
+   *
+   *       ...
+   *
+   *       FT_Done_Face( face );
+   *
+   *       if ( instance_idx < num_instances )
+   *         instance_idx++;
+   *       else
+   *       {
+   *         face_idx++;
+   *         instance_idx = 0;
+   *       }
+   *
+   *     } while ( face_idx < num_faces )
+   *   ```

+   *     The font bounding box.  The width and height of the `bbox` field of
+   *     @FT_FaceRec are used to determine the horizontal and vertical
+   *     scaling value, respectively.
+   *
+   *   FT_SIZE_REQUEST_TYPE_CELL ::
+   *     The `max_advance_width` field of @FT_FaceRec is used to determine
+   *     the horizontal scaling value; the vertical scaling value is
+   *     determined the same way as @FT_SIZE_REQUEST_TYPE_REAL_DIM does.
+   *     Finally, both scaling values are set to the smaller one.  This type
+   *     is useful if you want to specify the font size for, say, a window of
+   *     a given dimension and 80x24 cells.
+   *
+   *   FT_SIZE_REQUEST_TYPE_SCALES ::
+   *     Specify the scaling values directly.
+   *
+   * @note:
+   *   The above descriptions only apply to scalable formats.  For bitmap
+   *   formats, the behaviour is up to the driver.
+   *
+   *   See the note section of @FT_Size_Metrics if you wonder how size
+   *   requesting relates to scaling values.

+   * @function:
+   *   FT_Render_Glyph
+   *
+   * @description:
+   *   Convert a given glyph image to a bitmap.  It does so by inspecting the
+   *   glyph image format, finding the relevant renderer, and invoking it.
+   *
+   * @inout:
+   *   slot ::
+   *     A handle to the glyph slot containing the image to convert.
+   *
+   * @input:
+   *   render_mode ::
+   *     The render mode used to render the glyph image into a bitmap.  See
+   *     @FT_Render_Mode for a list of possible values.
+   *
+   *     If @FT_RENDER_MODE_NORMAL is used, a previous call of @FT_Load_Glyph
+   *     with flag @FT_LOAD_COLOR makes FT_Render_Glyph provide a default
+   *     blending of colored glyph layers associated with the current glyph
+   *     slot (provided the font contains such layers) instead of rendering
+   *     the glyph slot's outline.  This is an experimental feature; see
+   *     @FT_LOAD_COLOR for more information.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   To get meaningful results, font scaling values must be set with
+   *   functions like @FT_Set_Char_Size before calling `FT_Render_Glyph`.
+   *
+   *   When FreeType outputs a bitmap of a glyph, it really outputs an alpha
+   *   coverage map.  If a pixel is completely covered by a filled-in
+   *   outline, the bitmap contains 0xFF at that pixel, meaning that
+   *   0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100%
+   *   black (or 0% bright).  If a pixel is only 50% covered (value 0x80),
+   *   the pixel is made 50% black (50% bright or a middle shade of grey).
+   *   0% covered means 0% black (100% bright or white).
+   *
+   *   On high-DPI screens like on smartphones and tablets, the pixels are so
+   *   small that their chance of being completely covered and therefore
+   *   completely black are fairly good.  On the low-DPI screens, however,
+   *   the situation is different.  The pixels are too large for most of the
+   *   details of a glyph and shades of gray are the norm rather than the
+   *   exception.
+   *
+   *   This is relevant because all our screens have a second problem: they
+   *   are not linear.  1~+~1 is not~2.  Twice the value does not result in
+   *   twice the brightness.  When a pixel is only 50% covered, the coverage
+   *   map says 50% black, and this translates to a pixel value of 128 when
+   *   you use 8~bits per channel (0-255).  However, this does not translate
+   *   to 50% brightness for that pixel on our sRGB and gamma~2.2 screens.
+   *   Due to their non-linearity, they dwell longer in the darks and only a
+   *   pixel value of about 186 results in 50% brightness -- 128 ends up too
+   *   dark on both bright and dark backgrounds.  The net result is that dark
+   *   text looks burnt-out, pixely and blotchy on bright background, bright
+   *   text too frail on dark backgrounds, and colored text on colored
+   *   background (for example, red on green) seems to have dark halos or
+   *   'dirt' around it.  The situation is especially ugly for diagonal stems
+   *   like in 'w' glyph shapes where the quality of FreeType's anti-aliasing
+   *   depends on the correct display of grays.  On high-DPI screens where
+   *   smaller, fully black pixels reign supreme, this doesn't matter, but on
+   *   our low-DPI screens with all the gray shades, it does.  0% and 100%
+   *   brightness are the same things in linear and non-linear space, just
+   *   all the shades in-between aren't.
+   *
+   *   The blending function for placing text over a background is
+   *
+   *   ```
+   *     dst = alpha * src + (1 - alpha) * dst    ,
+   *   ```
+   *
+   *   which is known as the OVER operator.
+   *
+   *   To correctly composite an antialiased pixel of a glyph onto a surface,
+   *
+   *   1. take the foreground and background colors (e.g., in sRGB space)
+   *      and apply gamma to get them in a linear space,
+   *
+   *   2. use OVER to blend the two linear colors using the glyph pixel
+   *      as the alpha value (remember, the glyph bitmap is an alpha coverage
+   *      bitmap), and
+   *
+   *   3. apply inverse gamma to the blended pixel and write it back to
+   *      the image.
+   *
+   *   Internal testing at Adobe found that a target inverse gamma of~1.8 for
+   *   step~3 gives good results across a wide range of displays with an sRGB
+   *   gamma curve or a similar one.
+   *
+   *   This process can cost performance.  There is an approximation that
+   *   does not need to know about the background color; see
+   *   https://bel.fi/alankila/lcd/ and
+   *   https://bel.fi/alankila/lcd/alpcor.html for details.
+   *
+   *   **ATTENTION**: Linear blending is even more important when dealing
+   *   with subpixel-rendered glyphs to prevent color-fringing!  A
+   *   subpixel-rendered glyph must first be filtered with a filter that
+   *   gives equal weight to the three color primaries and does not exceed a
+   *   sum of 0x100, see section @lcd_rendering.  Then the only difference to
+   *   gray linear blending is that subpixel-rendered linear blending is done
+   *   3~times per pixel: red foreground subpixel to red background subpixel
+   *   and so on for green and blue.

+   * @description:
+   *   This is an interface to the 'COLR' table in OpenType fonts to
+   *   iteratively retrieve the colored glyph layers associated with the
+   *   current glyph slot.
+   *
+   *     https://docs.microsoft.com/en-us/typography/opentype/spec/colr
+   *
+   *   The glyph layer data for a given glyph index, if present, provides an
+   *   alternative, multi-colour glyph representation: Instead of rendering
+   *   the outline or bitmap with the given glyph index, glyphs with the
+   *   indices and colors returned by this function are rendered layer by
+   *   layer.
+   *
+   *   The returned elements are ordered in the z~direction from bottom to
+   *   top; the 'n'th element should be rendered with the associated palette
+   *   color and blended on top of the already rendered layers (elements 0,
+   *   1, ..., n-1).
+   *
+   * @input:
+   *   face ::
+   *     A handle to the parent face object.
+   *
+   *   base_glyph ::
+   *     The glyph index the colored glyph layers are associated with.
+   *
+   * @inout:
+   *   iterator ::
+   *     An @FT_LayerIterator object.  For the first call you should set
+   *     `iterator->p` to `NULL`.  For all following calls, simply use the
+   *     same object again.
+   *
+   * @output:
+   *   aglyph_index ::
+   *     The glyph index of the current layer.
+   *
+   *   acolor_index ::
+   *     The color index into the font face's color palette of the current
+   *     layer.  The value 0xFFFF is special; it doesn't reference a palette
+   *     entry but indicates that the text foreground color should be used
+   *     instead (to be set up by the application outside of FreeType).
+   *
+   *     The color palette can be retrieved with @FT_Palette_Select.
+   *
+   * @return:
+   *   Value~1 if everything is OK.  If there are no more layers (or if there
+   *   are no layers at all), value~0 gets returned.  In case of an error,
+   *   value~0 is returned also.
+   *
+   * @note:
+   *   This function is necessary if you want to handle glyph layers by
+   *   yourself.  In particular, functions that operate with @FT_GlyphRec
+   *   objects (like @FT_Get_Glyph or @FT_Glyph_To_Bitmap) don't have access
+   *   to this information.
+   *
+   *   Note that @FT_Render_Glyph is able to handle colored glyph layers
+   *   automatically if the @FT_LOAD_COLOR flag is passed to a previous call
+   *   to @FT_Load_Glyph.  [This is an experimental feature.]
+   *
+   * @example:
+   *   ```
+   *     FT_Color*         palette;

+   *   Unicode Variation Sequences
+   *
+   * @abstract:
+   *   The FreeType~2 interface to Unicode Variation Sequences (UVS), using
+   *   the SFNT cmap format~14.
+   *
+   * @description:
+   *   Many characters, especially for CJK scripts, have variant forms.  They
+   *   are a sort of grey area somewhere between being totally irrelevant and
+   *   semantically distinct; for this reason, the Unicode consortium decided
+   *   to introduce Variation Sequences (VS), consisting of a Unicode base
+   *   character and a variation selector instead of further extending the
+   *   already huge number of characters.
+   *
+   *   Unicode maintains two different sets, namely 'Standardized Variation
+   *   Sequences' and registered 'Ideographic Variation Sequences' (IVS),
+   *   collected in the 'Ideographic Variation Database' (IVD).
+   *
+   *     https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt
+   *     https://unicode.org/reports/tr37/ https://unicode.org/ivd/
+   *
+   *   To date (January 2017), the character with the most ideographic
+   *   variations is U+9089, having 32 such IVS.
+   *
+   *   Three Mongolian Variation Selectors have the values U+180B-U+180D; 256
+   *   generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F
+   *   and U+E0100-U+E01EF.  IVS currently use Variation Selectors from the
+   *   range U+E0100-U+E01EF only.
+   *
+   *   A VS consists of the base character value followed by a single
+   *   Variation Selector.  For example, to get the first variation of
+   *   U+9089, you have to write the character sequence `U+9089 U+E0100`.
+   *
+   *   Adobe and MS decided to support both standardized and ideographic VS
+   *   with a new cmap subtable (format~14).  It is an odd subtable because
+   *   it is not a mapping of input code points to glyphs, but contains lists
+   *   of all variations supported by the font.
+   *
+   *   A variation may be either 'default' or 'non-default' for a given font.
+   *   A default variation is the one you will get for that code point if you
+   *   look it up in the standard Unicode cmap.  A non-default variation is a
+   *   different glyph.
+   *

-   *
-   * @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;

-   *   switches warping on and off.
-   *
-   *   Warping only works in `normal' auto-hinting mode replacing it.
-   *   The idea of the code is to slightly scale and shift a glyph along
-   *   the non-hinted dimension (which is usually the horizontal axis) so
-   *   that as much of its segments are aligned (more or less) to the grid.
-   *   To find out a glyph's optimal scaling and shifting value, various
-   *   parameter combinations are tried and scored.
-   *
-   *   By default, warping is off.  The example below shows how to switch on
-   *   warping (omitting the error handling).

-   *
-   * @note:
-   *   This property can be used with @FT_Property_Get also.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable (using values 1 and 0 for `on' and `off', respectively).
-   *
-   *   The warping code can also change advance widths.  Have a look at the
-   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
-   *   for details on improving inter-glyph distances while rendering.
-   *
-   *   Since warping is a global property of the auto-hinter it is best to

-   *   *Experimental* *only*, *requires* *linear* *alpha* *blending* *and*
-   *   *gamma* *correction*
-   *
-   *   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.
-   *   The smaller the size (especially 9ppem and down), the higher the loss
-   *   of emboldening versus the CFF driver.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable similar to the CFF driver.  It can also be set per face
-   *   using @FT_Face_Properties with @FT_PARAM_TAG_STEM_DARKENING.

-   * @title:
-   *   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.

-   * @property:
-   *   random-seed
-   *
-   * @description:
-   *   By default, the seed value for the CFF `random' operator is set to a
-   *   random value.  However, mainly for debugging purposes, it is often
-   *   necessary to use a known value as a seed so that the pseudo-random
-   *   number sequences generated by `random' are repeatable.
-   *
-   *   The `random-seed' property does that.  Its argument is a signed 32bit
-   *   integer; if the value is zero or negative, the seed given by the
-   *   `intitialRandomSeed' private DICT operator in a CFF file gets used
-   *   (or a default value if there is no such operator).  If the value is
-   *   positive, use it instead of `initialRandomSeed', which is
-   *   consequently ignored.
-   *
-   * @note:
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable.  It can also be set per face using @FT_Face_Properties with
-   *   @FT_PARAM_TAG_RANDOM_SEED.

+   * @title:
+   *   Error Enumerations
+   *
+   * @abstract:
+   *   How to handle errors and error strings.
+   *
+   * @description:
+   *   The header file `fterrors.h` (which is automatically included by
+   *   `freetype.h` defines the handling of FreeType's enumeration
+   *   constants.  It can also be used to generate error message strings
+   *   with a small macro trick explained below.
+   *
+   *   **Error Formats**
+   *
+   *   The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
+   *   defined in `ftoption.h` in order to make the higher byte indicate the
+   *   module where the error has happened (this is not compatible with
+   *   standard builds of FreeType~2, however).  See the file `ftmoderr.h`
+   *   for more details.
+   *
+   *   **Error Message Strings**
+   *
+   *   Error definitions are set up with special macros that allow client
+   *   applications to build a table of error message strings.  The strings
+   *   are not included in a normal build of FreeType~2 to save space (most
+   *   client applications do not use them).
+   *
+   *   To do so, you have to define the following macros before including
+   *   this file.
+   *
+   *   ```
+   *     FT_ERROR_START_LIST
+   *   ```
+   *
+   *   This macro is called before anything else to define the start of the
+   *   error list.  It is followed by several `FT_ERROR_DEF` calls.
+   *
+   *   ```
+   *     FT_ERROR_DEF( e, v, s )
+   *   ```
+   *
+   *   This macro is called to define one single error.  'e' is the error
+   *   code identifier (e.g., `Invalid_Argument`), 'v' is the error's
+   *   numerical value, and 's' is the corresponding error string.
+   *
+   *   ```
+   *     FT_ERROR_END_LIST
+   *   ```
+   *
+   *   This macro ends the list.
+   *
+   *   Additionally, you have to undefine `FTERRORS_H_` before #including
+   *   this file.
+   *
+   *   Here is a simple example.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERRORDEF( e, v, s )  { e, s },
+   *     #define FT_ERROR_START_LIST     {
+   *     #define FT_ERROR_END_LIST       { 0, NULL } };
+   *
+   *     const struct
+   *     {
+   *       int          err_code;
+   *       const char*  err_msg;
+   *     } ft_errors[] =
+   *
+   *     #include FT_ERRORS_H
+   *   ```
+   *
+   *   An alternative to using an array is a switch statement.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERROR_START_LIST     switch ( error_code ) {
+   *     #define FT_ERRORDEF( e, v, s )    case v: return s;
+   *     #define FT_ERROR_END_LIST       }
+   *   ```
+   *
+   *   If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
+   *   be replaced with `FT_ERROR_BASE(error_code)` in the last example.

+   * @function:
+   *   FT_Glyph_Get_CBox
+   *
+   * @description:
+   *   Return a glyph's 'control box'.  The control box encloses all the
+   *   outline's points, including Bezier control points.  Though it
+   *   coincides with the exact bounding box for most glyphs, it can be
+   *   slightly larger in some situations (like when rotating an outline that
+   *   contains Bezier outside arcs).
+   *
+   *   Computing the control box is very fast, while getting the bounding box
+   *   can take much more time as it needs to walk over all segments and arcs
+   *   in the outline.  To get the latter, you can use the 'ftbbox'
+   *   component, which is dedicated to this single task.
+   *
+   * @input:
+   *   glyph ::
+   *     A handle to the source glyph object.
+   *
+   *   mode ::
+   *     The mode that indicates how to interpret the returned bounding box
+   *     values.
+   *
+   * @output:
+   *   acbox ::
+   *     The glyph coordinate bounding box.  Coordinates are expressed in
+   *     1/64th of pixels if it is grid-fitted.
+   *
+   * @note:
+   *   Coordinates are relative to the glyph origin, using the y~upwards
+   *   convention.
+   *
+   *   If the glyph has been loaded with @FT_LOAD_NO_SCALE, `bbox_mode` must
+   *   be set to @FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6
+   *   pixel format.  The value @FT_GLYPH_BBOX_SUBPIXELS is another name for
+   *   this constant.
+   *
+   *   If the font is tricky and the glyph has been loaded with
+   *   @FT_LOAD_NO_SCALE, the resulting CBox is meaningless.  To get
+   *   reasonable values for the CBox it is necessary to load the glyph at a
+   *   large ppem value (so that the hinting instructions can properly shift
+   *   and scale the subglyphs), then extracting the CBox, which can be
+   *   eventually converted back to font units.
+   *
+   *   Note that the maximum coordinates are exclusive, which means that one
+   *   can compute the width and height of the glyph image (be it in integer
+   *   or 26.6 pixels) as:
+   *
+   *   ```
+   *     width  = bbox.xMax - bbox.xMin;
+   *     height = bbox.yMax - bbox.yMin;
+   *   ```
+   *
+   *   Note also that for 26.6 coordinates, if `bbox_mode` is set to
+   *   @FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted,
+   *   which corresponds to:
+   *
+   *   ```
+   *     bbox.xMin = FLOOR(bbox.xMin);
+   *     bbox.yMin = FLOOR(bbox.yMin);
+   *     bbox.xMax = CEILING(bbox.xMax);
+   *     bbox.yMax = CEILING(bbox.yMax);
+   *   ```
+   *
+   *   To get the bbox in pixel coordinates, set `bbox_mode` to
+   *   @FT_GLYPH_BBOX_TRUNCATE.
+   *
+   *   To get the bbox in grid-fitted pixel coordinates, set `bbox_mode` to
+   *   @FT_GLYPH_BBOX_PIXELS.

+   *
+   * @description:
+   *   Convert a given glyph object to a bitmap glyph object.
+   *
+   * @inout:
+   *   the_glyph ::
+   *     A pointer to a handle to the target glyph.
+   *
+   * @input:
+   *   render_mode ::
+   *     An enumeration that describes how the data is rendered.
+   *
+   *   origin ::
+   *     A pointer to a vector used to translate the glyph image before
+   *     rendering.  Can be~0 (if no translation).  The origin is expressed
+   *     in 26.6 pixels.
+   *
+   *   destroy ::
+   *     A boolean that indicates that the original glyph image should be
+   *     destroyed by this function.  It is never destroyed in case of error.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   This function does nothing if the glyph format isn't scalable.
+   *
+   *   The glyph image is translated with the `origin` vector before
+   *   rendering.
+   *
+   *   The first parameter is a pointer to an @FT_Glyph handle, that will be
+   *   _replaced_ by this function (with newly allocated data).  Typically,
+   *   you would use (omitting error handling):
+   *
+   *   ```
+   *     FT_Glyph        glyph;
+   *     FT_BitmapGlyph  glyph_bitmap;
+   *
+   *
+   *     // load glyph
+   *     error = FT_Load_Char( face, glyph_index, FT_LOAD_DEFAULT );
+   *
+   *     // extract glyph image
+   *     error = FT_Get_Glyph( face->glyph, &glyph );
+   *
+   *     // convert to a bitmap (default render mode + destroying old)
+   *     if ( glyph->format != FT_GLYPH_FORMAT_BITMAP )
+   *     {
+   *       error = FT_Glyph_To_Bitmap( &glyph, FT_RENDER_MODE_NORMAL,
+   *                                     0, 1 );
+   *       if ( error ) // `glyph' unchanged
+   *         ...
+   *     }
+   *
+   *     // access bitmap content by typecasting
+   *     glyph_bitmap = (FT_BitmapGlyph)glyph;
+   *
+   *     // do funny stuff with it, like blitting/drawing
+   *     ...
+   *
+   *     // discard glyph image (bitmap or not)
+   *     FT_Done_Glyph( glyph );
+   *   ```
+   *
+   *   Here is another example, again without error handling:

+   *   ```
+   *     FT_Glyph  glyphs[MAX_GLYPHS]
+   *

+   *
+   * @description:
+   *   A structure used to describe a bitmap or pixmap to the raster.  Note
+   *   that we now manage pixmaps of various depths through the `pixel_mode`
+   *   field.
+   *
+   * @fields:
+   *   rows ::
+   *     The number of bitmap rows.
+   *
+   *   width ::
+   *     The number of pixels in bitmap row.
+   *
+   *   pitch ::
+   *     The pitch's absolute value is the number of bytes taken by one
+   *     bitmap row, including padding.  However, the pitch is positive when
+   *     the bitmap has a 'down' flow, and negative when it has an 'up' flow.
+   *     In all cases, the pitch is an offset to add to a bitmap pointer in
+   *     order to go down one row.
+   *
+   *     Note that 'padding' means the alignment of a bitmap to a byte
+   *     border, and FreeType functions normally align to the smallest
+   *     possible integer value.
+   *
+   *     For the B/W rasterizer, `pitch` is always an even number.
+   *
+   *     To change the pitch of a bitmap (say, to make it a multiple of 4),
+   *     use @FT_Bitmap_Convert.  Alternatively, you might use callback
+   *     functions to directly render to the application's surface; see the
+   *     file `example2.cpp` in the tutorial for a demonstration.
+   *
+   *   buffer ::
+   *     A typeless pointer to the bitmap buffer.  This value should be
+   *     aligned on 32-bit boundaries in most cases.
+   *
+   *   num_grays ::
+   *     This field is only used with @FT_PIXEL_MODE_GRAY; it gives the
+   *     number of gray levels used in the bitmap.
+   *
+   *   pixel_mode ::
+   *     The pixel mode, i.e., how pixel bits are stored.  See @FT_Pixel_Mode
+   *     for possible values.
+   *
+   *   palette_mode ::
+   *     This field is intended for paletted pixel modes; it indicates how
+   *     the palette is stored.  Not used currently.
+   *
+   *   palette ::
+   *     A typeless pointer to the bitmap palette; this field is intended for
+   *     paletted pixel modes.  Not used currently.

+   *
+   * @enum:
+   *   FT_OUTLINE_XXX
+   *
+   * @description:
+   *   A list of bit-field constants used for the flags in an outline's
+   *   `flags` field.
+   *
+   * @values:
+   *   FT_OUTLINE_NONE ::
+   *     Value~0 is reserved.
+   *
+   *   FT_OUTLINE_OWNER ::
+   *     If set, this flag indicates that the outline's field arrays (i.e.,
+   *     `points`, `flags`, and `contours`) are 'owned' by the outline
+   *     object, and should thus be freed when it is destroyed.
+   *
+   *   FT_OUTLINE_EVEN_ODD_FILL ::
+   *     By default, outlines are filled using the non-zero winding rule.  If
+   *     set to 1, the outline will be filled using the even-odd fill rule
+   *     (only works with the smooth rasterizer).
+   *
+   *   FT_OUTLINE_REVERSE_FILL ::
+   *     By default, outside contours of an outline are oriented in
+   *     clock-wise direction, as defined in the TrueType specification.
+   *     This flag is set if the outline uses the opposite direction
+   *     (typically for Type~1 fonts).  This flag is ignored by the scan
+   *     converter.
+   *
+   *   FT_OUTLINE_IGNORE_DROPOUTS ::
+   *     By default, the scan converter will try to detect drop-outs in an
+   *     outline and correct the glyph bitmap to ensure consistent shape
+   *     continuity.  If set, this flag hints the scan-line converter to
+   *     ignore such cases.  See below for more information.
+   *
+   *   FT_OUTLINE_SMART_DROPOUTS ::
+   *     Select smart dropout control.  If unset, use simple dropout control.
+   *     Ignored if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for more
+   *     information.
+   *
+   *   FT_OUTLINE_INCLUDE_STUBS ::
+   *     If set, turn pixels on for 'stubs', otherwise exclude them.  Ignored
+   *     if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for more
+   *     information.
+   *
+   *   FT_OUTLINE_HIGH_PRECISION ::
+   *     This flag indicates that the scan-line converter should try to
+   *     convert this outline to bitmaps with the highest possible quality.
+   *     It is typically set for small character sizes.  Note that this is
+   *     only a hint that might be completely ignored by a given
+   *     scan-converter.
+   *
+   *   FT_OUTLINE_SINGLE_PASS ::
+   *     This flag is set to force a given scan-converter to only use a
+   *     single pass over the outline to render a bitmap glyph image.
+   *     Normally, it is set for very large character sizes.  It is only a
+   *     hint that might be completely ignored by a given scan-converter.
+   *
+   * @note:
+   *   The flags @FT_OUTLINE_IGNORE_DROPOUTS, @FT_OUTLINE_SMART_DROPOUTS, and
+   *   @FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer.
+   *
+   *   There exists a second mechanism to pass the drop-out mode to the B/W
+   *   rasterizer; see the `tags` field in @FT_Outline.
+   *
+   *   Please refer to the description of the 'SCANTYPE' instruction in the
+   *   OpenType specification (in file `ttinst1.doc`) how simple drop-outs,
+   *   smart drop-outs, and stubs are defined.

+   *     The glyph image is a vectorial outline made of line segments and

-   *   LCD Filtering
+   *   Subpixel Rendering
    *
    * @abstract:
-   *   Reduce color fringes of subpixel-rendered bitmaps.
+   *   API to control subpixel rendering.
    *
    * @description:
-   *   Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
-   *   `ftoption.h', which enables patented ClearType-style rendering,
-   *   the LCD-optimized glyph bitmaps should be filtered to reduce color
-   *   fringes inherent to this technology.  The default FreeType LCD
-   *   rendering uses different technology, and API described below,
-   *   although available, does nothing.
+   *   FreeType provides two alternative subpixel rendering technologies. 
+   *   Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
+   *   `ftoption.h` file, this enables patented ClearType-style rendering. 
+   *   Otherwise, Harmony LCD rendering is enabled.  These technologies are
+   *   controlled differently and API described below, although always
+   *   available, performs its function when appropriate method is enabled
+   *   and does nothing otherwise.
    *
    *   ClearType-style LCD 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.
-   *
-   *   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.

-   *   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.
+   *   the stripe (usually horizontal RGB) by a factor of~3.  Using the
+   *   subpixels coverages unfiltered can create severe color fringes
+   *   especially when rendering thin features.  Indeed, to produce
+   *   black-on-white text, the nearby color subpixels must be dimmed
+   *   equally.
+   *
+   *   A good 5-tap FIR filter should be applied to subpixel coverages
+   *   regardless of pixel boundaries and should have these properties:
+   *
+   *   1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
+   *      any shifts in appearance.
+   *
+   *   2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
+   *      fringes by distributing the computed coverage for one subpixel to
+   *      all subpixels equally.
+   *
+   *   3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
+   *      overall brightness.
+   *
+   *   Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
+   *   forgiving of non-ideal gamma curves of a screen (and viewing angles),
+   *   beveled filters are fuzzier but more tolerant.
+   *
+   *   Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
+   *   API to specify a low-pass filter, which is then applied to
+   *   subpixel-rendered bitmaps generated through @FT_Render_Glyph.
+   *
+   *   Harmony LCD rendering is suitable to panels with any regular subpixel
+   *   structure, not just monitors with 3 color striped subpixels, as long
+   *   as the color subpixels have fixed positions relative to the pixel
+   *   center.  In this case, each color channel is then rendered separately
+   *   after shifting the outline opposite to the subpixel shift so that the
+   *   coverage maps are aligned.  This method is immune to color fringes
+   *   because the shifts do not change integral coverage.
+   *
+   *   The subpixel geometry must be specified by xy-coordinates for each
+   *   subpixel. By convention they may come in the RGB order: {{-1/3, 0},
+   *   {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
+   *   {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
+   *
+   *   Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
+   *   If one follows the RGB order convention, the same order applies to the
+   *   resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps.  Note,
+   *   however, that the coordinate frame for the latter must be rotated
+   *   clockwise.  Harmony with default LCD geometry is equivalent to
+   *   ClearType with light filter.
+   *
+   *   As a result of ClearType filtering or Harmony rendering, the
+   *   dimensions of LCD bitmaps can be 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 2~subpixels to
+   *   the left, and 2~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.
+   *
+   *   The ClearType and Harmony rendering is applicable to glyph bitmaps
+   *   rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
+   *   @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
+   *   is specified.  This API does not control @FT_Outline_Render and
+   *   @FT_Outline_Get_Bitmap.
+   *
+   *   The described algorithms can completely remove color artefacts when
+   *   combined with gamma-corrected alpha blending in linear space.  Each of
+   *   the 3~alpha values (subpixels) must by 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.

+   * @description:
+   *   The following types and functions are used to manage Multiple Master
+   *   fonts, i.e., the selection of specific design instances by setting
+   *   design axis coordinates.
+   *
+   *   Besides Adobe MM fonts, the interface supports Apple's TrueType GX and
+   *   OpenType variation fonts.  Some of the routines only work with Adobe
+   *   MM fonts, others will work with all three types.  They are similar
+   *   enough that a consistent interface makes sense.

+   *
+   *   num_designs ::
+   *     The number of designs; should be normally 2^num_axis for Adobe MM
+   *     fonts.  Not meaningful for TrueType GX or OpenType variation fonts
+   *     (where every glyph could have a different number of designs).
+   *
+   *   num_namedstyles ::
+   *     The number of named styles; a 'named style' is a tuple of design
+   *     coordinates that has a string ID (in the 'name' table) associated
+   *     with it.  The font can tell the user that, for example,
+   *     [Weight=1.5,Width=1.1] is 'Bold'.  Another name for 'named style' is
+   *     'named instance'.
+   *
+   *     For Adobe Multiple Masters fonts, this value is always zero because
+   *     the format does not support named styles.
+   *
+   *   axis ::
+   *     An axis descriptor table.  TrueType GX and OpenType variation fonts
+   *     contain slightly more data than Adobe MM fonts.  Memory management
+   *     of this pointer is done internally by FreeType.
+   *
+   *   namedstyle ::
+   *     A named style (instance) table.  Only meaningful for TrueType GX and

+   * @abstract:
+   *   Managing multiple sizes per face.
+   *
+   * @description:
+   *   When creating a new face object (e.g., with @FT_New_Face), an @FT_Size
+   *   object is automatically created and used to store all pixel-size
+   *   dependent information, available in the `face->size` field.
+   *
+   *   It is however possible to create more sizes for a given face, mostly
+   *   in order to manage several character pixel sizes of the same font
+   *   family and style.  See @FT_New_Size and @FT_Done_Size.
+   *
+   *   Note that @FT_Set_Pixel_Sizes and @FT_Set_Char_Size only modify the
+   *   contents of the current 'active' size; you thus need to use
+   *   @FT_Activate_Size to change it.
+   *
+   *   99% of applications won't need the functions provided here, especially
+   *   if they use the caching sub-system, so be cautious when using these.

-   *   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_ _Backward_ _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 backward 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 backward
-   *   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.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable (using values `35', `38', or `40').

-   * @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
-   *   TT_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.

-   *   The `version' field gives a rough orientation only, since some

-   *
-   *   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
-   *   16x1) grid lines per pixel for bytecode instructions like `MIRP'.
-   *   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.

+   *   Get the data offsets for a tag in a resource fork.  Offsets are stored
+   *   in an array because, in some cases, resources in a resource fork have
+   *   the same tag.
+   *
+   * @input:
+   *   library ::
+   *     A FreeType library instance.
+   *
+   *   stream ::
+   *     A file stream containing the resource fork.
+   *
+   *   map_offset ::
+   *     The file offset where the resource map starts.
+   *
+   *   rdata_pos ::
+   *     The file offset where the resource data starts.
+   *
+   *   tag ::
+   *     The resource tag.
+   *
+   *   sort_by_res_id ::
+   *     A Boolean to sort the fragmented resource by their ids.  The
+   *     fragmented resources for 'POST' resource should be sorted to restore
+   *     Type1 font properly.  For 'sfnt' resources, sorting may induce a
+   *     different order of the faces in comparison to that by QuickDraw API.
+   *
+   * @output:
+   *   offsets ::
+   *     The stream offsets for the resource data specified by 'tag'.  This
+   *     array is allocated by the function, so you have to call @ft_mem_free
+   *     after use.
+   *
+   *   count ::
+   *     The length of offsets array.
+   *
+   * @return:
+   *   FreeType error code.  FT_Err_Ok means success.
+   *
+   * @note:
+   *   Normally you should use `FT_Raccess_Get_HeaderInfo` to get the value
+   *   for `map_offset` and `rdata_pos`.

+   *
+   * @description:
+   *   A structure to model a TrueType horizontal header, the 'hhea' table,
+   *   as well as the corresponding horizontal metrics table, 'hmtx'.
+   *
+   * @fields:
+   *   Version ::
+   *     The table version.
+   *
+   *   Ascender ::
+   *     The font's ascender, i.e., the distance from the baseline to the
+   *     top-most of all glyph points found in the font.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the
+   *     font designer, and often reflects only a portion of the glyphs found
+   *     in the font (maybe ASCII).
+   *
+   *     You should use the `sTypoAscender` field of the 'OS/2' table instead
+   *     if you want the correct one.
+   *
+   *   Descender ::
+   *     The font's descender, i.e., the distance from the baseline to the
+   *     bottom-most of all glyph points found in the font.  It is negative.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the
+   *     font designer, and often reflects only a portion of the glyphs found
+   *     in the font (maybe ASCII).
+   *
+   *     You should use the `sTypoDescender` field of the 'OS/2' table
+   *     instead if you want the correct one.
+   *
+   *   Line_Gap ::
+   *     The font's line gap, i.e., the distance to add to the ascender and
+   *     descender to get the BTB, i.e., the baseline-to-baseline distance
+   *     for the font.
+   *
+   *   advance_Width_Max ::
+   *     This field is the maximum of all advance widths found in the font.
+   *     It can be used to compute the maximum width of an arbitrary string
+   *     of text.
+   *
+   *   min_Left_Side_Bearing ::
+   *     The minimum left side bearing of all glyphs within the font.
+   *
+   *   min_Right_Side_Bearing ::
+   *     The minimum right side bearing of all glyphs within the font.
+   *
+   *   xMax_Extent ::
+   *     The maximum horizontal extent (i.e., the 'width' of a glyph's
+   *     bounding box) for all glyphs in the font.
+   *
+   *   caret_Slope_Rise ::
+   *     The rise coefficient of the cursor's slope of the cursor
+   *     (slope=rise/run).
+   *
+   *   caret_Slope_Run ::
+   *     The run coefficient of the cursor's slope.
+   *
+   *   caret_Offset ::
+   *     The cursor's offset for slanted fonts.
+   *
+   *   Reserved ::
+   *     8~reserved bytes.
+   *
+   *   metric_Data_Format ::
+   *     Always~0.
+   *
+   *   number_Of_HMetrics ::
+   *     Number of HMetrics entries in the 'hmtx' table -- this value can be
+   *     smaller than the total number of glyphs in the font.
+   *
+   *   long_metrics ::
+   *     A pointer into the 'hmtx' table.
+   *
+   *   short_metrics ::
+   *     A pointer into the 'hmtx' table.
+   *
+   * @note:
+   *   For an OpenType variation font, the values of the following fields can
+   *   change after a call to @FT_Set_Var_Design_Coordinates (and friends) if
+   *   the font contains an 'MVAR' table: `caret_Slope_Rise`,
+   *   `caret_Slope_Run`, and `caret_Offset`.

+   *
+   * @description:
+   *   A structure used to model a TrueType vertical header, the 'vhea'
+   *   table, as well as the corresponding vertical metrics table, 'vmtx'.
+   *
+   * @fields:
+   *   Version ::
+   *     The table version.
+   *
+   *   Ascender ::
+   *     The font's ascender, i.e., the distance from the baseline to the
+   *     top-most of all glyph points found in the font.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the
+   *     font designer, and often reflects only a portion of the glyphs found
+   *     in the font (maybe ASCII).
+   *
+   *     You should use the `sTypoAscender` field of the 'OS/2' table instead
+   *     if you want the correct one.
+   *
+   *   Descender ::
+   *     The font's descender, i.e., the distance from the baseline to the
+   *     bottom-most of all glyph points found in the font.  It is negative.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the
+   *     font designer, and often reflects only a portion of the glyphs found
+   *     in the font (maybe ASCII).
+   *
+   *     You should use the `sTypoDescender` field of the 'OS/2' table
+   *     instead if you want the correct one.
+   *
+   *   Line_Gap ::
+   *     The font's line gap, i.e., the distance to add to the ascender and
+   *     descender to get the BTB, i.e., the baseline-to-baseline distance
+   *     for the font.
+   *
+   *   advance_Height_Max ::
+   *     This field is the maximum of all advance heights found in the font.
+   *     It can be used to compute the maximum height of an arbitrary string
+   *     of text.
+   *
+   *   min_Top_Side_Bearing ::
+   *     The minimum top side bearing of all glyphs within the font.
+   *
+   *   min_Bottom_Side_Bearing ::
+   *     The minimum bottom side bearing of all glyphs within the font.
+   *
+   *   yMax_Extent ::
+   *     The maximum vertical extent (i.e., the 'height' of a glyph's
+   *     bounding box) for all glyphs in the font.
+   *
+   *   caret_Slope_Rise ::
+   *     The rise coefficient of the cursor's slope of the cursor
+   *     (slope=rise/run).
+   *
+   *   caret_Slope_Run ::
+   *     The run coefficient of the cursor's slope.
+   *
+   *   caret_Offset ::
+   *     The cursor's offset for slanted fonts.
+   *
+   *   Reserved ::
+   *     8~reserved bytes.
+   *
+   *   metric_Data_Format ::
+   *     Always~0.
+   *
+   *   number_Of_VMetrics ::
+   *     Number of VMetrics entries in the 'vmtx' table -- this value can be
+   *     smaller than the total number of glyphs in the font.
+   *
+   *   long_metrics ::
+   *     A pointer into the 'vmtx' table.
+   *
+   *   short_metrics ::
+   *     A pointer into the 'vmtx' table.
+   *
+   * @note:
+   *   For an OpenType variation font, the values of the following fields can
+   *   change after a call to @FT_Set_Var_Design_Coordinates (and friends) if
+   *   the font contains an 'MVAR' table: `Ascender`, `Descender`,
+   *   `Line_Gap`, `caret_Slope_Rise`, `caret_Slope_Run`, and `caret_Offset`.

-   * Each zone is defined by a top and bottom edge in character space.
-   * Further, each zone is either a top zone or a bottom zone, as recorded

-   *
-   * The maximum number of `BlueValues' and `FamilyBlues' is 7 each.

-   *
-   * Blue zones are used to `capture' hints and force them to a common

-   * 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 preservation 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 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,
-   *
-   * {
-   *   FT_Error  e;
-   *
-   *
-   *   ...
-   *   e = FT_THROW( Out_Of_Memory );

+   *       `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.

+         * compatibility, operating systems and applications doing whatever
+         * they want, not to mention broken fonts.
+         *
+         * Not all fonts have an OS/2 table; in this case, we take the values
+         * in the horizontal header, although there is nothing stopping the
+         * values from being unreliable. Even with a OS/2 table, certain fonts
+         * set the sTypoAscender, sTypoDescender and sTypoLineGap fields to 0
+         * and instead correctly set usWinAscent and usWinDescent.
+         *
+         * As an example, Arial Narrow is shipped as four files ARIALN.TTF,
+         * ARIALNI.TTF, ARIALNB.TTF and ARIALNBI.TTF. Strangely, all fonts have

+         * values. The OS/2 table therefore cannot be trusted for computing the
+         * text height reliably.
+         *
+         * As a compromise, do the following:
+         *
+         * 1. If the OS/2 table exists and the fsSelection bit 7 is set
+         *    (USE_TYPO_METRICS), trust the font and use the sTypo* metrics.
+         * 2. Otherwise, use the `hhea' table's metrics.
+         * 3. If they are zero and the OS/2 table exists,
+         *    1. use the OS/2 table's sTypo* metrics if they are non-zero.

+   *
+   * Character codes are modelled by a series of ordered (increasing)
+   * intervals called segments.  Each segment has start and end codes,
+   * provided by the `startCount' and `endCount' arrays.  Segments must
+   * not overlap, and the last segment should always contain the value
+   * 0xFFFF for `endCount'.
+   *
+   * The fields `searchRange', `entrySelector' and `rangeShift' are better
+   * ignored (they are traces of over-engineering in the TrueType
+   * specification).
+   *
+   * Each segment also has a signed `delta', as well as an optional offset
+   * within the `glyphIds' table.
+   *
+   * If a segment's idOffset is 0, the glyph index corresponding to any
+   * charcode within the segment is obtained by adding the value of
+   * `idDelta' directly to the charcode, modulo 65536.
+   *
+   * Otherwise, a glyph index is taken from the glyph IDs sub-array for
+   * the segment, and the value of `idDelta' is added to it.
+   *
+   *
+   * Finally, note that a lot of fonts contain an invalid last segment,
+   * where `start' and `end' are correctly set to 0xFFFF but both `delta'
+   * and `offset' are incorrect (e.g., `opens___.ttf' which comes with
+   * OpenOffice.org).  We need special code to deal with them correctly.

+   *
+   * This is the new and improved Type 1 data loader for FreeType 2.  The
+   * old loader has several problems: it is slow, complex, difficult to
+   * maintain, and contains incredible hacks to make it accept some
+   * ill-formed Type 1 fonts without hiccup-ing.  Moreover, about 5% of
+   * the Type 1 fonts on my machine still aren't loaded correctly by it.
+   *
+   * This version is much simpler, much faster and also easier to read and
+   * maintain by a great order of magnitude.  The idea behind it is to
+   * _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
+   * time to generate parsing callback functions, the second time to
+   * generate a table of keywords (with pointers to the associated
+   * callback functions).
+   *
+   * 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
+   * hinter will replace the clumsy `t1hinter'.
