+// This class provides a wrapper around BVH tree, which contains most of the functionality
+// for a dynamic BVH with templated leaf size.
+// However BVH also adds facilities for pairing, to maintain compatibility with Godot 3.2.
+// Pairing is a collision pairing system, on top of the basic BVH.
+
+// Some notes on the use of BVH / Octree from Godot 3.2.
+// This is not well explained elsewhere.
+// The rendering tree mask and types that are sent to the BVH are NOT layer masks.
+// They are INSTANCE_TYPES (defined in visual_server.h), e.g. MESH, MULTIMESH, PARTICLES etc.
+// Thus the lights do no cull by layer mask in the BVH.
+
+// Layer masks are implemented in the renderers as a later step, and light_cull_mask appears to be
+// implemented in GLES3 but not GLES2. Layer masks are not yet implemented for directional lights.

 	<description>
 		[Decal]s are used to project a texture onto a [Mesh] in the scene. Use Decals to add detail to a scene without affecting the underlying [Mesh]. They are often used to add weathering to building, add dirt or mud to the ground, or add variety to props. Decals can be moved at any time, making them suitable for things like blob shadows or laser sight dots.
 		They are made of an [AABB] and a group of [Texture2D]s specifying [Color], normal, ORM (ambient occlusion, roughness, metallic), and emission. Decals are projected within their [AABB] so altering the orientation of the Decal affects the direction in which they are projected. By default, Decals are projected down (i.e. from positive Y to negative Y).
-		The [Texture2D]s associated with the Decal are automatically stored in a texture atlas which is used for drawing the decals so all decals can be drawn at once. Godot uses clustered decals, meaning they are stored in cluster data and drawn when the mesh is drawn, they are not drawn as a postprocessing effect after.

 		Plugin for adding custom property editors on inspector.
 	</brief_description>
 	<description>
-		This plugins allows adding custom property editors to [EditorInspector].
+		These plugins allow adding custom property editors to [EditorInspector].
 		Plugins are registered via [method EditorPlugin.add_inspector_plugin].
 		When an object is edited, the [method can_handle] function is called and must return [code]true[/code] if the object type is supported.
 		If supported, the function [method parse_begin] will be called, allowing to place custom controls at the beginning of the class.
 		Subsequently, the [method parse_category] and [method parse_property] are called for every category and property. They offer the ability to add custom controls to the inspector too.
-		Finally [method parse_end] will be called.
+		Finally, [method parse_end] will be called.
 		On each of these calls, the "add" functions can be called.

They precompute the effect of objects that emit light and the effect of static geometry to simulate the behavior of complex light in real-time. [GIProbe]s need to be baked before using, however, once baked, dynamic objects will receive light from them. Further, lights can be fully dynamic or baked.
 		Having [GIProbe]s in a scene can be expensive, the quality of the probe can be turned down in exchange for better performance in the [ProjectSettings] using [member ProjectSettings.rendering/global_illumination/gi_probes/quality].

 		A GraphNode is a container. Each GraphNode can have several input and output slots, sometimes referred to as ports, allowing connections between GraphNodes. To add a slot to GraphNode, add any [Control]-derived child node to it.
 		After adding at least one child to GraphNode new sections will be automatically created in the Inspector called 'Slot'. When 'Slot' is expanded you will see list with index number for each slot. You can click on each of them to expand further.
-		In the Inspector you can enable (show) or disable (hide) slots. By default all slots are disabled so you may not see any slots on your GraphNode initially. You can assign a type to each slot. Only slots of the same type will be able to connect to each other. You can also assign colors to slots. A tuple of input and output slots is defined for each GUI element included in the GraphNode. Input connections are on the left and output connections are on the right side of GraphNode. Only enabled slots are counted as connections.

+		Hyper-text transfer protocol client (sometimes called "User Agent"). Used to make HTTP requests to download web content, upload files and other data or to communicate with various services, among other use cases. [b]See the [HTTPRequest] node for a higher-level alternative.[/b]
 		[b]Note:[/b] This client only needs to connect to a host once (see [method connect_to_host]) to send multiple requests. Because of this, methods that take URLs usually take just the part after the host instead of the full URL, as the client is already connected to a host. See [method request] for a full example and to get started.
 		A [HTTPClient] should be reused between multiple requests or to connect to different hosts instead of creating one client per request. Supports SSL and SSL server certificate verification. HTTP status codes in the 2xx range indicate success, 3xx redirection (i.e. "try again, but over here"), 4xx something was wrong with the request, and 5xx something went wrong on the server's side.
 		For more information on HTTP, see https://developer.mozilla.org/en-US/docs/Web/HTTP (or read RFC 2616 to get it straight from the source: https://tools.ietf.org/html/rfc2616).

 		MultiMesh provides low-level mesh instancing. Drawing thousands of [MeshInstance3D] nodes can be slow, since each object is submitted to the GPU then drawn individually.
 		MultiMesh is much faster as it can draw thousands of instances with a single draw call, resulting in less API overhead.
-		As a drawback, if the instances are too far away of each other, performance may be reduced as every single instance will always rendered (they are spatially indexed as one, for the whole object).

 	<description>
-		NavigationServer2D is the server responsible for all 2D navigation. It creates the agents, maps, and regions for navigation to work as expected. This keeps tracks of any call and executes them during the sync phase. This means that you can request any change to the map, using any thread, without worrying.
+		NavigationServer2D is the server responsible for all 2D navigation. It handles several objects, namely maps, regions and agents.
+		Maps are made up of regions, which are made of navigation polygons. Together, they define the navigable areas in the 2D world. For two regions to be connected to each other, they must share a similar edge. An edge is considered connected to another if both of its two vertices are at a distance less than [code]edge_connection_margin[/code] to the respective other edge's vertex.
+		You may assign navigation layers to regions with [method NavigationServer2D.region_set_layers], which then can be checked upon when requesting a path with [method NavigationServer2D.map_get_path]. This allows allowing or forbidding some areas to 2D objects.
+		To use the collision avoidance system, you may use agents. You can set an agent's target velocity, then the servers will emit a callback with a modified velocity.
+		[b]Note:[/b] the collision avoidance system ignores regions. Using the modified velocity as-is might lead to pushing and agent outside of a navigable area. This is a limitation of the collision avoidance system, any more complex situation may require the use of the physics engine.

+				[b]Note:[/b] This method is the legacy implementation for connecting signals. The recommended modern approach is to use [method Signal.connect] and to use [method Callable.bind] to add and validate parameter binds. Both syntaxes are shown below.
 				A signal can only be connected once to a [Callable]. It will throw an error if already connected, unless the signal was connected with [constant CONNECT_REFERENCE_COUNTED]. To avoid this, first, use [method is_connected] to check for existing connections.
 				If the callable's target is destroyed in the game's lifecycle, the connection will be lost.

+				This method is potentially slower than [code]decompress[/code], as it may have to re-allocate its output buffer multiple times while decompressing, whereas [code]decompress[/code] knows it's output buffer size from the beginning.
 				GZIP has a maximal compression ratio of 1032:1, meaning it's very possible for a small compressed payload to decompress to a potentially very large output. To guard against this, you may provide a maximum size this function is allowed to allocate in bytes via [code]max_output_size[/code]. Passing -1 will allow for unbounded output. If any positive value is passed, and the decompression exceeds that amount in bytes, then an error will be returned.

 		Godot loads resources in the editor or in exported games using ResourceFormatLoaders. They are queried automatically via the [ResourceLoader] singleton, or when a resource with internal dependencies is loaded. Each file type may load as a different resource type, so multiple ResourceFormatLoaders are registered in the engine.
 		Extending this class allows you to define your own loader. Be sure to respect the documented return types and values. You should give it a global class name with [code]class_name[/code] for it to be registered. Like built-in ResourceFormatLoaders, it will be called automatically when loading resources of its handled type(s). You may also implement a [ResourceFormatSaver].
-		[b]Note:[/b] You can also extend [EditorImportPlugin] if the resource type you need exists but Godot is unable to load its format. Choosing one way over another depends if the format is suitable or not for the final exported game. For example, it's better to import [code].png[/code] textures as [code].stex[/code] ([StreamTexture2D]) first, so they can be loaded with better efficiency on the graphics card.

+		This node implements simulated 2D physics. You do not control a RigidBody2D directly. Instead, you apply forces to it (gravity, impulses, etc.) and the physics simulation calculates the resulting movement based on its mass, friction, and other physical properties.
 		A RigidBody2D has 4 behavior [member mode]s: Rigid, Static, Character, and Kinematic.
 		[b]Note:[/b] You should not change a RigidBody2D's [code]position[/code] or [code]linear_velocity[/code] every frame or even very often. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state.
 		Please also keep in mind that physics bodies manage their own transform which overwrites the ones you set. So any direct or indirect transformation (including scaling of the node or its parent) will be visible in the editor only, and immediately reset at runtime.

 	<description>
 		As one of the most important classes, the [SceneTree] manages the hierarchy of nodes in a scene as well as scenes themselves. Nodes can be added, retrieved and removed. The whole scene tree (and thus the current scene) can be paused. Scenes can be loaded, switched and reloaded.
-		You can also use the [SceneTree] to organize your nodes into groups: every node can be assigned as many groups as you want to create, e.g. a "enemy" group. You can then iterate these groups or even call methods and set properties on all the group's members at once.

 		[SceneTree] is the default [MainLoop] implementation used by scenes, and is thus in charge of the game loop.

[StringName] ensures that only one instance of a given name exists (so two [StringName]s with the same value are the same object). Comparing them is much faster than with regular [String]s, because only the pointers are compared, not the whole strings.

This mode presents problems when doing [code]flip_h[/code], [code]flip_v[/code] and [code]transpose[/code] tile operations on non-homogeneous isometric tiles (e.g. 2:1), in which the texture could not coincide with the collision, thus it is not recommended for isometric or non-square tiles.

The first accepts an [enum TransitionType] constant, and refers to the way the timing of the animation is handled (see [url=https://easings.net/]easings.net[/url] for some examples). The second accepts an [enum EaseType] constant, and controls where the [code]trans_type[/code] is applied to the interpolation (in the beginning, the end, or both). If you don't know which transition and easing to pick, you can try different [enum TransitionType] constants with [constant EASE_IN_OUT], and use the one that looks best.

-		Boolean is a built-in type. There are two boolean values: [code]true[/code] and [code]false[/code]. You can think of it as an switch with on or off (1 or 0) setting. Booleans are used in programming for logic in condition statements, like [code]if[/code] statements.
+		Boolean is a built-in type. There are two boolean values: [code]true[/code] and [code]false[/code]. You can think of it as a switch with on or off (1 or 0) setting. Booleans are used in programming for logic in condition statements, like [code]if[/code] statements.
 		Booleans can be directly used in [code]if[/code] statements. The code below demonstrates this on the [code]if can_shoot:[/code] line. You don't need to use [code]== true[/code], you only need [code]if can_shoot:[/code]. Similarly, use [code]if not can_shoot:[/code] rather than [code]== false[/code].

Returns [constant OK] if a client was created, [constant ERR_ALREADY_IN_USE] if this NetworkedMultiplayerENet instance already has an open connection (in which case you need to call [method close_connection] first) or [constant ERR_CANT_CREATE] if the client could not be created. If [code]local_port[/code] is specified, the client will also listen to the given port; this is useful for some NAT traversal techniques.

-    // * This code assumes that the ray's position and direction are in 'cell coordinates', which means
-    //   that one unit equals one cell in all directions.
-    // * When the ray doesn't start within the voxel grid, calculate the first position at which the
-    //   ray could enter the grid. If it never enters the grid, there is nothing more to do here.
-    // * Also, it is important to test when the ray exits the voxel grid when the grid isn't infinite.
-    // * The Point3D structure is a simple structure having three integer fields (X, Y and Z).

+BMP File Reader/Writer Implementation
+Anton Gerdelan
+Version: 3.1 18 March 2020.
+Licence: see bottom of file.
+C89 ( Implementation is C99 )
+
+Contributors:
+- Anton Gerdelan - Initial code.
+- Saija Sorsa    - Fuzz testing.
+
+Instructions:
+- Just drop this header, and the matching .c file into your project.
+- To get debug printouts during parsing define APG_BMP_DEBUG_OUTPUT.
+
+Advantages:
+- The implementation is fast, simple, and supports more formats than most BMP reader libraries.
+- The reader function is fuzzed with AFL https://lcamtuf.coredump.cx/afl/.
+- The reader is robust to large files and malformed files, and will return any valid partial data in an image.
+- Reader supports 32bpp (with alpha channel), 24bpp, 8bpp, 4bpp, and 1bpp monochrome BMP images.
+- Reader handles indexed BMP images using a colour palette.
+- Writer supports 32bpp RGBA and 24bpp uncompressed RGB images.
+
+Current Limitations:
+- 16-bit images not supported (don't have any samples to test on).
+- No support for interleaved channel bit layouts eg RGB101010 RGB555 RGB565.
+- No support for compressed BMP images, although in practice these are not used.
+- Output images with alpha channel are written in BITMAPINFOHEADER format.
+  For better alpha support in other apps the 124-bit v5 header could be used instead,
+	at the cost of some backward compatibility and bloat.
+
+To Do:
+- FUZZING
+  - create a unique fuzz test set for (8,4,1 BPP).
+- (maybe) FEATURE Flipping the image based on negative width and height in header, and/or function arguments. 
+- (maybe) PERF ifdef intrinsics/asm for bitscan. Platform-specific code so won't include unless necessary.
+- (maybe) FEATURE Add parameter for padding output memory to eg 4-byte alignment or n channels.
+- (maybe) FEATURE Improved apps support in alpha channel writing (using v5 header).

+// Release notes for January 20, 2017 version:
+//
+// The unit tests have been refactored.  They no longer assert on an error, instead they return a pass/fail condition
+// The unit-tests now test 10,000 random float and int values against each intrinsic.
+//
+// SSE2NEON now supports 95 SSE intrinsics.  39 of them have formal unit tests which have been implemented and
+// fully tested on NEON/ARM.  The remaining 56 still need unit tests implemented.
+//
+// A struct is now defined in this header file called 'SIMDVec' which can be used by applications which
+// attempt to access the contents of an _m128 struct directly.  It is important to note that accessing the __m128
+// struct directly is bad coding practice by Microsoft: @see: https://msdn.microsoft.com/en-us/library/ayeb3ayc.aspx
+//
+// However, some legacy source code may try to access the contents of an __m128 struct directly so the developer
+// can use the SIMDVec as an alias for it.  Any casting must be done manually by the developer, as you cannot
+// cast or otherwise alias the base NEON data type for intrinsic operations.
+//
+// A bug was found with the _mm_shuffle_ps intrinsic.  If the shuffle permutation was not one of the ones with
+// a custom/unique implementation causing it to fall through to the default shuffle implementation it was failing
+// to return the correct value.  This is now fixed.
+//
+// A bug was found with the _mm_cvtps_epi32 intrinsic.  This converts floating point values to integers.
+// It was not honoring the correct rounding mode.  In SSE the default rounding mode when converting from float to int
+// is to use 'round to even' otherwise known as 'bankers rounding'.  ARMv7 did not support this feature but ARMv8 does.
+// As it stands today, this header file assumes ARMv8.  If you are trying to target really old ARM devices, you may get
+// a build error.
+//
+// Support for a number of new intrinsics was added, however, none of them yet have unit-tests to 100% confirm they are
+// producing the correct results on NEON.  These unit tests will be added as soon as possible.
+//
+// Here is the list of new instrinsics which have been added:
+//
+// _mm_cvtss_f32     :  extracts the lower order floating point value from the parameter
+// _mm_add_ss        : adds the scalar single - precision floating point values of a and b
+// _mm_div_ps        : Divides the four single - precision, floating - point values of a and b.
+// _mm_div_ss        : Divides the scalar single - precision floating point value of a by b.
+// _mm_sqrt_ss       : Computes the approximation of the square root of the scalar single - precision floating point value of in.
+// _mm_rsqrt_ps      : Computes the approximations of the reciprocal square roots of the four single - precision floating point values of in.
+// _mm_comilt_ss     : Compares the lower single - precision floating point scalar values of a and b using a less than operation
+// _mm_comigt_ss     : Compares the lower single - precision floating point scalar values of a and b using a greater than operation.
+// _mm_comile_ss     :  Compares the lower single - precision floating point scalar values of a and b using a less than or equal operation.
+// _mm_comige_ss     : Compares the lower single - precision floating point scalar values of a and b using a greater than or equal operation.
+// _mm_comieq_ss     :  Compares the lower single - precision floating point scalar values of a and b using an equality operation.
+// _mm_comineq_s     :  Compares the lower single - precision floating point scalar values of a and b using an inequality operation
+// _mm_unpackhi_epi8 : Interleaves the upper 8 signed or unsigned 8 - bit integers in a with the upper 8 signed or unsigned 8 - bit integers in b.
+// _mm_unpackhi_epi16:  Interleaves the upper 4 signed or unsigned 16 - bit integers in a with the upper 4 signed or unsigned 16 - bit integers in b.

+  This file implements the intersection of a ray with a round linear
+  curve segment. We define the geometry of such a round linear curve
+  segment from point p0 with radius r0 to point p1 with radius r1
+  using the cone that touches spheres p0/r0 and p1/r1 tangentially
+  plus the sphere p1/r1. We denote the tangentially touching cone from
+  p0/r0 to p1/r1 with cone(p0,r0,p1,r1) and the cone plus the ending
+  sphere with cone_sphere(p0,r0,p1,r1).
+
+  For multiple connected round linear curve segments this construction
+  yield a proper shape when viewed from the outside. Using the
+  following CSG we can also handle the interiour in most common cases:
+
+     round_linear_curve(pl,rl,p0,r0,p1,r1,pr,rr) =
+       cone_sphere(p0,r0,p1,r1) - cone(pl,rl,p0,r0) - cone(p1,r1,pr,rr)
+
+  Thus by subtracting the neighboring cone geometries, we cut away
+  parts of the center cone_sphere surface which lie inside the
+  combined curve. This approach works as long as geometry of the
+  current cone_sphere penetrates into direct neighbor segments only,
+  and not into segments further away.
+  
+  To construct a cone that touches two spheres at p0 and p1 with r0
+  and r1, one has to increase the cone radius at r0 and r1 to obtain
+  larger radii w0 and w1, such that the infinite cone properly touches
+  the spheres.  From the paper "Ray Tracing Generalized Tube
+  Primitives: Method and Applications"
+  (https://www.researchgate.net/publication/334378683_Ray_Tracing_Generalized_Tube_Primitives_Method_and_Applications)
+  one can derive the following equations for these increased
+  radii:
+
+     sr = 1.0f / sqrt(1-sqr(dr)/sqr(p1-p0))
+     w0 = sr*r0
+     w1 = sr*r1
+
+  Further, we want the cone to start where it touches the sphere at p0
+  and to end where it touches sphere at p1.  Therefore, we need to
+  construct clipping locations y0 and y1 for the start and end of the
+  cone. These start and end clipping location of the cone can get
+  calculated as:
+
+     Y0 =               - r0 * (r1-r0) / length(p1-p0)
+     Y1 = length(p1-p0) - r1 * (r1-r0) / length(p1-p0)
+
+  Where the cone starts a distance Y0 and ends a distance Y1 away of
+  point p0 along the cone center. The distance between Y1-Y0 can get
+  calculated as:
+
+    dY = length(p1-p0) - (r1-r0)^2 / length(p1-p0)
+
+  In the code below, Y will always be scaled by length(p1-p0) to
+  obtain y and you will find the terms r0*(r1-r0) and
+  (p1-p0)^2-(r1-r0)^2.

+             
+               Y = (p-p0)*(p1-p0)/length(p1-p0)
+             
+             This value y is the distance to the projection point from

+             
+               Y0 =               - r0 * (r1-r0) / length(p1-p0)
+               Y1 = length(p1-p0) - r1 * (r1-r0) / length(p1-p0)
+             
+             Thus to test if the point p is accepted by the first

+             is accepted by the second clipping plane we need to test
+             Y < Y1.
+             
+             By multiplying the calculations with length(p1-p0) these

+             This function tests whether a point lies inside the capped cone

+
+             Therefore one has to check if the point is inside the
+             region defined by the cone clipping planes, which is
+             performed similar as in the previous function.
+             
+             To perform the inside cone test we need to project the

+             
+               dP = p1-p0
+               Y = (p-p0)*dP/length(dP)
+                           
+             This value Y is the distance to the projection point from
+             p0. To obtain a parameter value u going from 0 to 1 along
+             the line p0->p1 we calculate:
+             
+               U = Y/length(dP)
+             
+             The radii to use at points p0 and p1 are:
+

+               w1 = sr * r1
+               dw = w1-w0
+             
+             Using these radii and u one can directly test if the point
+             lies inside the cone using the formula dP*dP < wy*wy with:
+             
+               wy = w0 + u*dw
+               py = p0 + u*dP - p
+                          
+             By multiplying the calculations with length(p1-p0) and
+             inserting the definition of w can obtain simpler equations:
+             
+               y = (p-p0)*dP
+               ry = r0 + y/dP^2 * dr
+               wy = sr*ry        
+               py = p0 + y/dP^2*dP - p
+               y0 =      - r0 * dr
+               y1 = dP^2 - r1 * dr
+             
+             Thus for the in-cone test we get:
+             
+                    py^2 < wy^2
+               <=>  py^2 < sr^2 * ry^2
+               <=>  py^2 * ( dP^2 - dr^2 ) < dP^2 * ry^2
+             
+             This can further get simplified to:
+             
+               (p0-p)^2 * (dP^2 - dr^2) - y^2 < dP^2 * r0^2 + 2.0f*r0*dr*y;

+          This function intersects a ray with a cone that touches a
+          start sphere p0/r0 and end sphere p1/r1.
+          
+          To find this ray/cone intersections one could just
+          calculate radii w0 and w1 as described above and use a
+          standard ray/cone intersection routine with these
+          radii. However, it turns out that calculations can get
+          simplified when deriving a specialized ray/cone
+          intersection for this special case. We perform
+          calculations relative to the cone origin p0 and define:
+            
+            O  = ray_org - p0
+            dO = ray_dir
+            dP = p1-p0
+            dr = r1-r0
+            dw = w1-w0
+            
+          For some t we can compute the potential hit point h = O + t*dO and
+          project it onto the cone vector dP to obtain u = (h*dP)/(dP*dP). In
+          case of an intersection, the squared distance from the hit point
+          projected onto the cone center line to the hit point should be equal
+          to the squared cone radius at u:
+            
+            (u*dP - h)^2 = (w0 + u*dw)^2
+           
+          Inserting the definition of h, u, w0, and dw into this formula, then
+          factoring out all terms, and sorting by t^2, t^1, and t^0 terms
+          yields a quadratic equation to solve.
+            
+          Inserting u:
+            ( (h*dP)*dP/dP^2 - h )^2 = ( w0 + (h*dP)*dw/dP^2 )^2
+            
+          Multiplying by dP^4:
+            ( (h*dP)*dP - h*dP^2 )^2 = ( w0*dP^2 + (h*dP)*dw )^2
+            
+          Inserting w0 and dw:
+            ( (h*dP)*dP - h*dP^2 )^2 = ( r0*dP^2 + (h*dP)*dr )^2 / (1-dr^2/dP^2)
+            ( (h*dP)*dP - h*dP^2 )^2 *(dP^2 - dr^2) = dP^2 * ( r0*dP^2 + (h*dP)*dr )^2
+            
+          Now one can insert the definition of h, factor out, and presort by t:
+            ( ((O + t*dO)*dP)*dP - (O + t*dO)*dP^2 )^2 *(dP^2 - dr^2) = dP^2 * ( r0*dP^2 + ((O + t*dO)*dP)*dr )^2
+            ( (O*dP)*dP-O*dP^2 + t*( (dO*dP)*dP - dO*dP^2 ) )^2 *(dP^2 - dr^2) = dP^2 * ( r0*dP^2 + (O*dP)*dr + t*(dO*dP)*dr )^2
+            
+          Factoring out further and sorting by t^2, t^1 and t^0 yields:
+            
+            0 =   t^2 * [ ((dO*dP)*dP - dO-dP^2)^2 * (dP^2 - dr^2) - dP^2*(dO*dP)^2*dr^2 ]
+              + 2*t^1 * [ ((O*dP)*dP - O*dP^2) * ((dO*dP)*dP - dO*dP^2) * (dP^2 - dr^2) - dP^2*(r0*dP^2 + (O*dP)*dr)*(dO*dP)*dr ]
+              +   t^0 * [ ( (O*dP)*dP - O*dP^2)^2 * (dP^2-dr^2) - dP^2*(r0*dP^2 + (O*dP)*dr)^2 ]
+            
+          This can be simplified to:

+             0 =   t^2 * [ (dP^2 - dr^2)*dO^2 - (dO*dP)^2 ]

+           This function calculates the geometry normal of some cone hit.
+           
+           For a given hit point h (relative to p0) with a cone
+           starting at p0 with radius w0 and ending at p1 with
+           radius w1 one normally calculates the geometry normal by
+           first calculating the parmetric u hit location along the
+           cone:
+           
+             u = dot(h,dP)/dP^2
+           
+           Using this value one can now directly calculate the
+           geometry normal by bending the connection vector (h-u*dP)
+           from hit to projected hit with some cone dependent value
+           dw/sqrt(dP^2) * normalize(dP):
+           
+             Ng = normalize(h-u*dP) - dw/length(dP) * normalize(dP)
+           
+           The length of the vector (h-u*dP) can also get calculated
+           by interpolating the radii as w0+u*dw which yields:
+           
+             Ng = (h-u*dP)/(w0+u*dw) - dw/dP^2 * dP
+           
+           Multiplying with (w0+u*dw) yield a scaled Ng':
+           
+             Ng' = (h-u*dP) - (w0+u*dw)*dw/dP^2*dP
+           
+           Inserting the definition of w0 and dw and refactoring
+           yield a furhter scaled Ng'':
+           
+             Ng'' = (dP^2 - dr^2) (h-q) - (r0+u*dr)*dr*dP
+           
+           Now inserting the definition of u gives and multiplying
+           with the denominator yields:
+           
+             Ng''' = (dP^2-dr^2)*(dP^2*h-dot(h,dP)*dP) - (dP^2*r0+dot(h,dP)*dr)*dr*dP
+           
+           Factoring out, cancelling terms, dividing by dP^2, and
+           factoring again yields finally:
+           
+             Ng'''' = (dP^2-dr^2)*h - dP*(dot(h,dP) + r0*dr)

+ *  the ray origin into the origin of the coordinate system and then
+ *  uses Pluecker coordinates for the intersection. Due to the shift,

-# Etc2Comp - Texture to ETC2 compressor
-
-Etc2Comp is a command line tool that converts textures (e.g. bitmaps)
-into the [ETC2](https://en.wikipedia.org/wiki/Ericsson_Texture_Compression)
-format. The tool is built with a focus on encoding performance
-to reduce the amount of time required to compile asset heavy applications as
-well as reduce overall application size.
-
-This repo provides source code that can be compiled into a binary. The
-binary can then be used to convert textures to the ETC2 format.
-
-Important: This is not an official Google product. It is an experimental
-library published as-is. Please see the CONTRIBUTORS.md file for information
-about questions or issues.
-
-## Setup
-This project uses [CMake](https://cmake.org/) to generate platform-specific
-build files:
- - Linux: make files
- - OS X: Xcode workspace files
- - Microsoft Windows: Visual Studio solution files
- - Note: CMake supports other formats, but this doc only provides steps for
- one of each platform for brevity.
-
-Refer to each platform's setup section to setup your environment and build
-an Etc2Comp binary. Then skip to the usage section of this page for examples
-of how to use the library.
-
-### Setup for OS X
- build tested on this config:
-  OS X 10.9.5 i7 16GB RAM
-  Xcode 5.1.1
-  cmake 3.2.3
-  
-Start by downloading and installing the following components if they are not
-already installed on your development machine.
- - *Xcode* version 5.1.1, or greater
- - [CMake](https://cmake.org/download/) version 3.2.3, or greater
-
-To build the Etc2Comp binary:
- 1. Open a *Terminal* window and navigate to the project directory.
- 1. Run `mkdir build_xcode`
- 1. Run `cd build_xcode`
- 1. Run `cmake -G Xcode ../`
- 1. Open *Xcode* and import the `build_xcode/EtcTest.xcodeproj` file.
- 1. Open the Product menu and choose Build For -> Running.
- 1. Once the build succeeds the binary located at `build_xcode/EtcTool/Debug/EtcTool`
-can be executed.
-
-Optional
-Xcode EtcTool ‘Run’ preferences
-note: if the build_xcode/EtcTest.xcodeproj is manually deleted then some Xcode preferences 
-will need to be set by hand after cmake is run (these prefs are retained across 
-cmake updates if the .xcodeproj is not deleted/removed)
-
-1. Set the active scheme to ‘EtcTool’
-1. Edit the scheme
-1. Select option ‘Run EtcTool’, then tab ‘Arguments’. 
-Add this launch argument: ‘-argfile ../../EtcTool/args.txt’
-1. Select tab ‘Options’ and set a custom working directory to: ‘$(SRCROOT)/Build_Xcode/EtcTool’
-
-### SetUp for Windows
-
-1. Open a *Terminal* window and navigate to the project directory.
-1. Run `mkdir build_vs`
-1. Run `cd build_vs`
-1. Run CMAKE, noting what build version you need, and pointing to the parent directory as the source root; 
-  For VS 2013 : `cmake -G "Visual Studio 12 2013 Win64" ../`
-  For VS 2015 : `cmake -G "Visual Studio 14 2015 Win64" ../`
-  NOTE: To see what supported Visual Studio outputs there are, run `cmake -G`
-1. open the 'EtcTest' solution
-1. make the 'EtcTool' project the start up project 
-1. (optional) in the project properties, under 'Debugging ->command arguments' 
-add the argfile textfile thats included in the EtcTool directory. 
-example: -argfile C:\etc2\EtcTool\Args.txt
-
-### Setup For Linux
-The Linux build was tested on this config:
-  Ubuntu desktop 14.04
-  gcc/g++ 4.8
-  cmake 2.8.12.2
-
-1. Verify linux has cmake and C++-11 capable g++ installed
-1. Open shell
-1. Run `mkdir build_linux`
-1. Run `cd build_linux`
-1. Run `cmake ../`
-1. Run `make`
-1. navigate to the newly created EtcTool directory `cd EtcTool`
-1. run the executable: `./EtcTool -argfile ../../EtcTool/args.txt`
-
-Skip to the <a href="#usage">Usage</a> section for more information about using the
-tool.
-
-## Usage
-
-### Command Line Usage
-EtcTool can be run from the command line with the following usage:
-    etctool.exe source_image [options ...] -output encoded_image
-
-The encoder will use an array of RGBA floats read from the source_image to create 
-an ETC1 or ETC2 encoded image in encoded_image.  The RGBA floats should be in the 
-range [0:1].
-
-Options:
-
-    -analyze <analysis_folder>
-    -argfile <arg_file>           additional command line arguments read from a file
-    -blockAtHV <H V>              encodes a single block that contains the
-                                  pixel specified by the H V coordinates
-    -compare <comparison_image>   compares source_image to comparison_image
-    -effort <amount>              number between 0 and 100 to specify the encoding quality 
-                                  (100 is the highest quality)
-    -errormetric <error_metric>   specify the error metric, the options are
-                                  rgba, rgbx, rec709, numeric and normalxyz
-    -format <etc_format>          ETC1, RGB8, SRGB8, RGBA8, SRGB8, RGB8A1,
-                                  SRGB8A1 or R11
-    -help                         prints this message
-    -jobs or -j <thread_count>    specifies the number of threads (default=1)
-    -normalizexyz                 normalize RGB to have a length of 1
-    -verbose or -v                shows status information during the encoding
-                                  process
-	-mipmaps or -m <mip_count>    sets the maximum number of mipaps to generate (default=1)
-	-mipwrap or -w <x|y|xy>       sets the mipmap filter wrap mode (default=clamp)
-
-* -analyze will run an analysis of the encoding and place it in folder 
-"analysis_folder" (e.g. ../analysis/kodim05).  within the analysis_folder, a folder 
-will be created with a name of the current date/time (e.g. 20151204_153306).  this 
-date/time folder is used to compare encodings of the same texture over time.  
-within the date/time folder is a text file with several encoding stats and a 2x png 
-image showing the encoding mode for each 4x4 block.
-
-* -argfile allows additional command line arguments to be placed in a text file
-
-* -blockAtHV selects the 4x4 pixel subset of the source image at position (H,V).  
-This is mainly used for debugging
-
-* -compare compares the source image to the created encoded image. The encoding
-will dictate what error analysis is used in the comparison.
-
-* -effort uses an "amount" between 0 and 100 to determine how much additional effort 
-to apply during the encoding.
-
-* -errormetric selects the fitting algorithm used by the encoder.  "rgba" calculates 
-RMS error using RGB components that are weighted by A.  "rgbx" calculates RMS error 
-using RGBA components, where A is treated as an additional data channel, instead of 
-as alpha.  "rec709" is similar to "rgba", except the RGB components are also weighted 
-according to Rec709.  "numeric" calculates RMS error using unweighted RGBA components.  
-"normalize" calculates error based on dot product and vector length for RGB and RMS 
-error for A.
-
-* -help prints out the usage message
-
-* -jobs enables multi-threading to speed up image encoding
-
-* -normalizexyz normalizes the source RGB to have a length of 1.
-
-* -verbose shows information on the current encoding process. It will then display the 
-PSNR and time time it took to encode the image.
-
-* -mipmaps takes an argument that specifies how many mipmaps to generate from the 
-source image.  The mipmaps are generated with a lanczos3 filter using edge clamping.
-If the mipmaps option is not specified no mipmaps are created.
-
-* -mipwrap takes an argument that specifies the mipmap filter wrap mode.  The options 
-are "x", "y" and "xy" which specify wrapping in x only, y only or x and y respectively.
-The default options are clamping in both x and y.
-
-Note: Path names can use slashes or backslashes.  The tool will convert the 
-slashes to the appropriate polarity for the current platform.
-
-
-## API
-
-The library supports two different APIs - a C-like API that is not heavily 
-class-based and a class-based API.
-
-main() in EtcTool.cpp contains an example of both APIs.
-
-The Encode() method now returns an EncodingStatus that contains bit flags for
-reporting various warnings and flags encountered when encoding.

+Overview of changes leading to 2.8.0
+Tuesday, March 16, 2021
+====================================
+- Shape joining scripts other than Arabic/Syriac using the Universal Shaping Engine.
+  Previously these were shaped using the generalized Arabic shaper. (David Corbett)
+- Fix regression in shaping of U+0B55 ORIYA SIGN OVERLINE. (David Corbett)
+- Update language tags. (David Corbett)
+- Variations: reduce error: do not round each interpolated delta. (Just van Rossum) 
+- Documentation improvements. (Khaled Hosny, Nathan Willis)
+- Subsetter improvements: subsets most, if not all, lookup types now. (Garret Rieger, Qunxin Liu)
+- Fuzzer-found fixes and other improvements when memory failures happen. (Behdad)
+- Removed most atomic implementations now that we have C++11 atomic impl. (Behdad)
+- General codebase upkeep; using more C++11 features: constexpr constructors, etc. (Behdad)
