The main use case is cropping out textures from a texture atlas, which is a big texture file that packs multiple smaller textures. Consists of a [Texture2D] for the [member atlas], a [member region] that defines the area of [member atlas] to use, and a [member margin] that defines the border width.
+		[AtlasTexture] cannot be used in an [AnimatedTexture], cannot be tiled in nodes such as [TextureRect], and does not work properly if used inside of other [AtlasTexture] resources. Multiple [AtlasTexture] resources can be used to crop multiple textures from the atlas. Using a texture atlas helps to optimize video memory costs and render calls compared to using multiple small files.

 	<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.

 		[GIProbe]s are used to provide high-quality real-time indirect light to scenes. 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].

-		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.

 		[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).
+		As a drawback, if the instances are too far away of each other, performance may be reduced as every single instance will always render (they are spatially indexed as one, for the whole object).
 		Since instances may have any behavior, the AABB used for visibility must be provided by the user.

 		Server interface for low-level 2D navigation access
 	</brief_description>
 	<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.
+		This server 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.

 		Server interface for low-level 3D navigation access
 	</brief_description>
 	<description>
-		NavigationServer3D is the server responsible for all 3D 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.
+		NavigationServer3D is the server responsible for all 3D navigation. It handles several objects, namely maps, regions and agents.
+		Maps are made up of regions, which are made of navigation meshes. Together, they define the navigable areas in the 3D 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 NavigationServer3D.region_set_layers], which then can be checked upon when requesting a path with [method NavigationServer3D.map_get_path]. This allows allowing or forbidding some areas to 3D 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.
+		This server 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.

+				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.

 				Copies the viewport to a region of the screen specified by [code]rect[/code]. If [method viewport_set_render_direct_to_screen] is [code]true[/code], then the viewport does not use a framebuffer and the contents of the viewport are rendered directly to screen. However, note that the root viewport is drawn last, therefore it will draw over the screen. Accordingly, you must set the root viewport to an area that does not cover the area that you have attached this viewport to.
 				For example, you can set the root viewport to not render at all with the following code:
-				[codeblock]
+				FIXME: The method seems to be non-existent.
+				[codeblocks]

 		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.

 		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.

 		SpinBox is a numerical input text field. It allows entering integers and floats.
 		[b]Example:[/b]
-		[codeblock]
+		[codeblocks]
+		[gdscript]
 		var spin_box = SpinBox.new()
 		add_child(spin_box)
 		var line_edit = spin_box.get_line_edit()
 		line_edit.context_menu_enabled = false
 		spin_box.align = LineEdit.ALIGN_RIGHT
-		[/codeblock]
+		[/gdscript]
+		[csharp]
+		var spinBox = new SpinBox();
+		AddChild(spinBox);
+		var lineEdit = spinBox.GetLineEdit();
+		lineEdit.ContextMenuEnabled = false;
+		spinBox.Align = LineEdit.AlignEnum.Right;
+		[/csharp]
+		[/codeblocks]
 		The above code will create a [SpinBox], disable context menu on it and set the text alignment to right.
 		See [Range] class for more options over the [SpinBox].
 		[b]Note:[/b] [SpinBox] relies on an underlying [LineEdit] node. To theme a [SpinBox]'s background, add theme items for [LineEdit] and customize them.

 		The [SurfaceTool] is used to construct a [Mesh] by specifying vertex attributes individually. It can be used to construct a [Mesh] from a script. All properties except indices need to be added before calling [method add_vertex]. For example, to add vertex colors and UVs:
-		[codeblock]
+		[codeblocks]
+		[gdscript]
 		var st = SurfaceTool.new()
 		st.begin(Mesh.PRIMITIVE_TRIANGLES)
 		st.set_color(Color(1, 0, 0))
 		st.set_uv(Vector2(0, 0))
 		st.set_vertex(Vector3(0, 0, 0))
-		[/codeblock]
+		[/gdscript]
+		[csharp]
+		var st = new SurfaceTool();
+		st.Begin(Mesh.PrimitiveType.Triangles);
+		st.SetColor(new Color(1, 0, 0));
+		st.SetUv(new Vector2(0, 0));
+		st.SetVertex(new Vector3(0, 0, 0));
+		[/csharp]
+		[/codeblocks]
 		The above [SurfaceTool] now contains one vertex of a triangle which has a UV coordinate and a specified [Color]. If another vertex were added without calling [method set_uv] or [method set_color], then the last values would be used.
 		Vertex attributes must be passed [b]before[/b] calling [method add_vertex]. Failure to do so will result in an error when committing the vertex information to a mesh.
 		Additionally, the attributes used before the first vertex is added determine the format of the mesh. For example, if you only add UVs to the first vertex, you cannot add color to any of the subsequent vertices.

 		Tweens are useful for animations requiring a numerical property to be interpolated over a range of values. The name [i]tween[/i] comes from [i]in-betweening[/i], an animation technique where you specify [i]keyframes[/i] and the computer interpolates the frames that appear between them.
 		[Tween] is more suited than [AnimationPlayer] for animations where you don't know the final values in advance. For example, interpolating a dynamically-chosen camera zoom value is best done with a [Tween] node; it would be difficult to do the same thing with an [AnimationPlayer] node.
 		Here is a brief usage example that makes a 2D node move smoothly between two positions:
-		[codeblock]
+		[codeblocks]
+		[gdscript]
 		var tween = get_node("Tween")
 		tween.interpolate_property($Node2D, "position",
 		        Vector2(0, 0), Vector2(100, 100), 1,
 		        Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
 		tween.start()
-		[/codeblock]
-		Many methods require a property name, such as [code]"position"[/code] above. You can find the correct property name by hovering over the property in the Inspector. You can also provide the components of a property directly by using [code]"property:component"[/code] (eg. [code]position:x[/code]), where it would only apply to that particular component.

+		var tween = GetNode&lt;Tween&gt;("Tween");

+		    Tween.TransitionType.Linear, Tween.EaseType.InOut);

 		Many of the methods accept [code]trans_type[/code] and [code]ease_type[/code]. 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.

 		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].

+// 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)

+ *  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

-                                  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,

-    -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)
