+====
+Shortly after 2021-04-08, we will be removing the old-style group blocks
+(contained within the `groups` section at the top of the XML registry)
+The groups are intended to contain all the possible legal values
+for corresponding function parameters, but it is likely that many

+ES specifications, and the many extensions to those specifications.
+As of Wednesday 8th January 2020, these group blocks have been
+deprecated in favour of group attributes declared inline with
+the enumerant itself, which are currently the only actively updated
+source for groupings. For more information, see public issue

+ This extension interacts with NV_mesh_shader.
+
+Overview
+
+ This extension builds on top of the NV_shading_rate_image extension to
+ provide OpenGL API support for using a per-primitive shading rate value to
+ control the computation of the rate used to process each fragment.
+
+ In the NV_shading_rate_image extension, the shading rate for each fragment
+ produced by a primitive is determined by looking up a texel in the bound
+ shading rate image and using that value as an index into a shading rate
+ palette. That extension provides a separate shading rate image lookup
+ enable and palette for each viewport. When a primitive is rasterized, the
+ implementation uses the enable and palette associated with the primitive's
+ viewport to determine the shading rate.
+
+ This extension decouples the shading rate image enables and palettes from
+ viewports. The number of enables/palettes now comes from the
+ implementation-dependent constant SHADING_RATE_IMAGE_PALETTE_COUNT_NV. When
+ SHADING_RATE_IMAGE_PER_PRIMITIVE_NV (added here) is enabled, the value of
+ the new gl_ShadingRateNV built-in output is used to select an enable and
+ palette to determine the shading rate. Otherwise, the viewport number for
+ the primitive is used, as in NV_shading_rate_image.

+
+ (modify the introduction of the shading rate image functionality to decouple

+
+ When using a shading rate image (Section 14.4.1), rasterization may produce
+ fragments covering multiple pixels, where each pixel is treated as a sample.
+ If any of the SHADING_RATE_IMAGE_NV enables is enabled, primitives will be
+ processed with multisample rasterization rules, regardless of the
+ MULTISAMPLE enable or the value of SAMPLE_BUFFERS. ...
+
+
+ Modify Section 14.4.1, Shading Rate Image, as added by the
+ NV_shading_rate_image extension.
+
+ (rework the introduction of the shading rate image functionality to decouple
+ shading rate image enables and viewports)
+
+ Applications can specify the use of a shading rate that varies by (x,y)
+ location using a _shading rate image_. For each primitive, the shading rate
+ image is enabled or disabled by selecting a single enable in an array of
+ enables whose size is given by the implementation-dependent constant
+ SHADING_RATE_IMAGE_PALETTE_COUNT_NV. Use of a shading rate image is enabled
+ or disabled globally by using Enable or Disable with target
+ SHADING_RATE_IMAGE_NV. A single shading rate image enable can be modified
+ by calling Enablei or Disablei with the constant SHADING_RATE_IMAGE_NV and
+ the index of the selected enable. The shading rate image may only be used
+ with a framebuffer object. When rendering to the default framebuffer, the
+ shading rate image enables are ignored and operations in this section are
+ disabled. In the initial state, all shading rate image enables are
+ disabled.
+
+ The method used to select a single shading rate image enable used to process
+ each primitive is controlled by calling Enable or Disable with the target
+ SHADING_RATE_IMAGE_PER_PRIMITIVE_NV. When enabled, a shading rate enable
+ used for a primitive is selected using an index taken from the value of the
+ built-in output gl_ShadingRateNV for the primitive's provoking vertex. If
+ the value of gl_ShadingRateNV is negative or greater than or equal to the
+ number of shading rate enables, the shading rate used for a primitive is
+ undefined. When SHADING_RATE_IMAGE_PER_PRIMITIVE_NV is disabled, a shading
+ rate enable is selected using the index of the viewport used for processing
+ the primitive. In the initial state, SHADING_RATE_IMAGE_PER_PRIMITIVE_NV is
+ disabled.
+
+
+ (rework the introduction of the shading rate image functionality to decouple
+ shading rate image palettes and viewports)
+
+ A shading rate index is mapped to a _base shading rate_ using a lookup table
+ called the shading rate image palette. There is a separate palette
+ associated with each shading rate image enable. As with the shading rate
+ image enables, a single palette is selected for a primitive according to the
+ enable SHADING_RATE_IMAGE_PER_PRIMITIVE_NV. The number of palettes and the
+ number of entries in each palette are given by the implementation-dependent
+ constants SHADING_RATE_IMAGE_PALETTE_COUNT_NV and
+ SHADING_RATE_IMAGE_PALETTE_SIZE_NV, respectively. The base shading rate for
+ an (x,y) coordinate with a shading rate index of <i> will be given by entry
+ <i> of the selected palette. If the shading rate index is greater than or
+ equal to the palette size, the results of the palette lookup are undefined.
+
+
+ (rework the introduction of ShadingRateImagePaletteNV to decouple shading
+ rate image palettes and viewports)
+
+ Shading rate image palettes are updated using the command
+
+ void ShadingRateImagePaletteNV(uint viewport, uint first, sizei count,
+ const enum *rates);
+
+ <viewport> specifies the number of the palette that should be updated.
+ [[ Note: The formal parameter name <viewport> is a remnant of the
+ original NV_shading_rate_image extension, where palettes were tightly
+ coupled with viewports. ]] <rates> is an array ...
+
+
+ (modify the discussion of ShadingRateImagePaletteNV errors to decouple
+ shading rate image palettes and viewports)
+
+ INVALID_VALUE is generated if <viewport> is greater than or equal to
+ SHADING_RATE_IMAGE_PALETTE_COUNT_NV.
+
+ INVALID_VALUE is generated if <first> plus <count> is greater than
+ SHADING_RATE_IMAGE_PALETTE_SIZE_NV.
+
+
+ (modify the discussion of GetShadingRateImagePaletteNV to decouple shading
+ rate image palettes and viewports)
+
+ Individual entries in the shading rate palette can be queried using the
+ command:
+
+ void GetShadingRateImagePaletteNV(uint viewport, uint entry,
+ enum *rate);
+
+ where <viewport> specifies the number of the palette to query and...
+ <entry> specifies the palette entry number. [[ Note: The formal
+ parameter name <viewport> is a remnant of the original
+ NV_shading_rate_image extension, where palettes were tightly coupled
+ with viewports. ]] A single enum from Table X.1 is returned in <rate>.
+
+ Errors
+
+ INVALID_VALUE is generated if <viewport> is greater than or equal to
+ SHADING_RATE_IMAGE_PALETTE_COUNT_NV.
+
+ INVALID_VALUE is generated if <first> plus <count> is greater than
+ SHADING_RATE_IMAGE_PALETTE_SIZE_NV.
+
+
+ Modify Section 14.9.3, Multisample Fragment Operations, as edited by
+ NV_shading_rate_image.
+
+ (modify the discussion of the shading rate image multisample functionality
+ to decouple shading rate image enables and viewports)
+
+ ... This step is skipped if MULTISAMPLE is disabled or if the value of
+ SAMPLE_BUFFERS is not one, unless one or more of the SHADING_RATE_IMAGE_NV
+ enables are enabled.
+
+
+Dependencies on NV_mesh_shader
+
+ When NV_mesh_shader is supported, the "NV_primitive_shading_rate" GLSL
+ extension allows multi-view mesh shaders to write separate per-primitive
+ shading rates for each view using the built-in gl_ShadingRatePerViewNV[].
+ When gl_ShadingRatePerViewNV[] is used with
+ SHADING_RATE_IMAGE_PER_PRIMITIVE_NV enabled, a separate shading rate image
+ enable and palette will be used for each view.

+
+ (1) How should we name this extension?
+

+ shading functionality added by NV_shading_rate_image.
+
+ (2) Do we need to add queries like LAYER_PROVOKING_VERTEX and
+ VIEWPORT_INDEX_PROVOKING_VERTEX to determine the vertex used to obtain
+ the per-primitive shading rate for each primitive?
+
+ RESOLVED: No -- we will always use the provoking vertex. In the event
+ that this extension is standardized in the future with behavior that
+ diverges between implementations, such a query could be added as part of
+ that effort.

+ Requires OpenGL ES 2.0
+
+ This extension is written based on the wording of the OpenGL ES 3.2
+ Specification.
+
+Overview
+
+ Frame extrapolation is the process of producing a new, future frame
+ based on the contents of two previously rendered frames. It may be
+ used to produce high frame rate display updates without incurring the
+ full cost of traditional rendering at the higher framerate.
+
+ This extension adds support for frame extrapolation in OpenGL ES by
+ adding a function which takes three textures. The first two are used
+ in sequence as the source frames, from which the extrapolated frame
+ is derived. The extrapolated frame is stored in the third texture.
+
+New Procedures and Functions
+
+ void ExtrapolateTex2DQCOM(uint src1,
+ uint src2,
+ uint output,
+ float scaleFactor);
+
+Additions to Chapter 8 of the OpenGL ES 3.2 Specification
+
+ 8.24 Frame Extrapolation
+
+ The command
+
+ void ExtrapolateTex2DQCOM(uint src1, uint src2,
+ uint output, float scaleFactor);
+
+ is used to produce an extrapolated frame based on the contents of
+ two previous frames. <src1> and <src2> specify the two previously
+ rendered frames, in order, which will be used as the basis of the
+ extrapolation. The three textures provided must have the same
+ dimensions and format. While <src1>, <src2> and <output> can
+ have multiple levels the implementation only reads from or writes
+ to the base level.
+
+ The texture contents provided in the two source textures represent
+ frame contents at two points in time. <scaleFactor> defines the amount
+ of time into the future the extrapolation is to target, based on the
+ delta in time between the two source textures.
+
+ For example, a value of 1.0 for <scaleFactor> will produce an
+ extrapolated frame that is as far into the future beyond 'src2'
+ as the time delta between 'src1' and 'src2'. A value of 0.5
+ for 'scaleFactor' targets a time that is a half step in the
+ future (compared to the full step delta between the two source frames).
+
+ Specifying an accurate scale factor is important for producing smooth
+ animation. An application that is displaying to the user alternating
+ rendered and extrapolated frames would use a scale factor of 0.5 so
+ that the extrapolated frame has contents which fall halfways between the
+ last rendered frame and the next rendered frame to come in the future.
+ Negative <scaleFactor> values produce frames targeting times before
+ that represented by the contents of <src2>.
+
+ Table 8.28: Compatible formats for <src1>, <src2> and <output>
+
+ Internal Format

+ RGBA8
+ RGB8
+ R8
+ RGBA16F

+
+Errors
+
+ INVALID_VALUE is generated if scaleFactor is equal to 0.
+
+ INVALID_OPERATION is generated if the texture formats of src1, src2 and
+ output are not identical.
+
+ INVALID_OPERATION is generated if the texture dimensions of src1, src2
+ and output are not identical.
+
+ INVALID_OPERATION is generated if the texture formats of src1, src2 and
+ output are not one of the formats listed in table 8.28.
+
+Issues
+
+ (1) Why is the extrapolation quality not defined?
+
+ Resolved: The intention of this specification is to extrapolate a new
+ texture based on the two input textures. Implementations should aim to
+ produce the highest quality extrapolation but since the results are
+ extrapolations there are no prescribed steps for how the textures must
+ be generated.

-# [<img src="https://khan.github.io/KaTeX/katex-logo.svg" width="130" alt="KaTeX">](https://khan.github.io/KaTeX/) [](https://travis-ci.org/Khan/KaTeX)
-
-[](https://gitter.im/Khan/KaTeX?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
-
-KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web.
-
- * **Fast:** KaTeX renders its math synchronously and doesn't need to reflow the page. See how it compares to a competitor in [this speed test](http://jsperf.com/katex-vs-mathjax/).
- * **Print quality:** KaTeX’s layout is based on Donald Knuth’s TeX, the gold standard for math typesetting.
- * **Self contained:** KaTeX has no dependencies and can easily be bundled with your website resources.
- * **Server side rendering:** KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML.
-
-KaTeX supports all major browsers, including Chrome, Safari, Firefox, Opera, and IE 8 - IE 11. A list of supported commands can be on the [wiki](https://github.com/Khan/KaTeX/wiki/Function-Support-in-KaTeX).
-
-## Usage
-
-You can [download KaTeX](https://github.com/khan/katex/releases) and host it on your server or include the `katex.min.js` and `katex.min.css` files on your page directly from a CDN:
-
-```html
-<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.6.0/katex.min.css">
-<script src="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.6.0/katex.min.js"></script>
-```
-
-#### In-browser rendering
-
-Call `katex.render` with a TeX expression and a DOM element to render into:
-
-```js
-katex.render("c = \\pm\\sqrt{a^2 + b^2}", element);
-```
-
-If KaTeX can't parse the expression, it throws a `katex.ParseError` error.
-
-#### Server side rendering or rendering to a string
-
-To generate HTML on the server or to generate an HTML string of the rendered math, you can use `katex.renderToString`:
-
-```js
-var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}");
-// '<span class="katex">...</span>'
-```
-
-Make sure to include the CSS and font files, but there is no need to include the JavaScript. Like `render`, `renderToString` throws if it can't parse the expression.
-
-#### Rendering options
-
-You can provide an object of options as the last argument to `katex.render` and `katex.renderToString`. Available options are:
-
-- `displayMode`: `boolean`. If `true` the math will be rendered in display mode, which will put the math in display style (so `\int` and `\sum` are large, for example), and will center the math on the page on its own line. If `false` the math will be rendered in inline mode. (default: `false`)
-- `throwOnError`: `boolean`. If `true`, KaTeX will throw a `ParseError` when it encounters an unsupported command. If `false`, KaTeX will render the unsupported command as text in the color given by `errorColor`. (default: `true`)
-- `errorColor`: `string`. A color string given in the format `"#XXX"` or `"#XXXXXX"`. This option determines the color which unsupported commands are rendered in. (default: `#cc0000`)
-
-For example:
-
-```js
-katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, { displayMode: true });
-```
-
-#### Automatic rendering of math on a page
-
-Math on the page can be automatically rendered using the auto-render extension. See [the Auto-render README](contrib/auto-render/README.md) for more information.

-/**
- * This file contains the parser used to parse out a TeX expression from the
- * input. Since TeX isn't context-free, standard parsers don't work particularly
- * well.
- *
- * The strategy of this parser is as such:
- *
- * The main functions (the `.parse...` ones) take a position in the current
- * parse string to parse tokens from. The lexer (found in Lexer.js, stored at
- * this.lexer) also supports pulling out tokens at arbitrary places. When
- * individual tokens are needed at a position, the lexer is called to pull out a
- * token, which is then used.
- *
- * The parser has a property called "mode" indicating the mode that
- * the parser is currently in. Currently it has to be one of "math" or
- * "text", which denotes whether the current environment is a math-y
- * one or a text-y one (e.g. inside \text). Currently, this serves to
- * limit the functions which can be used in text mode.
- *
- * The main functions then return an object which contains the useful data that
- * was parsed at its given point, and a new position at the end of the parsed
- * data. The main functions can call each other and continue the parsing by
- * using the returned position as a new starting point.
- *
- * There are also extra `.handle...` functions, which pull out some reused
- * functionality into self-contained functions.
- *
- * The earlier functions return ParseNodes.
- * The later functions (which are called deeper in the parse) sometimes return
- * ParseFuncOrArgument, which contain a ParseNode as well as some data about
- * whether the parsed object is a function which is missing some arguments, or a
- * standalone object which can be used as an argument to another function.

-/* This file contains a list of functions that we parse, identified by
- * the calls to defineFunction.
- *
- * The first argument to defineFunction is a single name or a list of names.
- * All functions named in such a list will share a single implementation.
- *
- * Each declared function can have associated properties, which
- * include the following:
- *
- * - numArgs: The number of arguments the function takes.
- * If this is the only property, it can be passed as a number
- * instead of an element of a properties object.
- * - argTypes: (optional) An array corresponding to each argument of the
- * function, giving the type of argument that should be parsed. Its
- * length should be equal to `numArgs + numOptionalArgs`. Valid
- * types:
- * - "size": A size-like thing, such as "1em" or "5ex"
- * - "color": An html color, like "#abc" or "blue"
- * - "original": The same type as the environment that the
- * function being parsed is in (e.g. used for the
- * bodies of functions like \color where the first
- * argument is special and the second argument is
- * parsed normally)
- * Other possible types (probably shouldn't be used)
- * - "text": Text-like (e.g. \text)
- * - "math": Normal math
- * If undefined, this will be treated as an appropriate length
- * array of "original" strings
- * - greediness: (optional) The greediness of the function to use ungrouped
- * arguments.
- *
- * E.g. if you have an expression
- * \sqrt \frac 1 2
- * since \frac has greediness=2 vs \sqrt's greediness=1, \frac
- * will use the two arguments '1' and '2' as its two arguments,
- * then that whole function will be used as the argument to
- * \sqrt. On the other hand, the expressions
- * \frac \frac 1 2 3
- * and
- * \frac \sqrt 1 2
- * will fail because \frac and \frac have equal greediness
- * and \sqrt has a lower greediness than \frac respectively. To
- * make these parse, we would have to change them to:
- * \frac {\frac 1 2} 3
- * and
- * \frac {\sqrt 1} 2
- *
- * The default value is `1`
- * - allowedInText: (optional) Whether or not the function is allowed inside
- * text mode (default false)
- * - numOptionalArgs: (optional) The number of optional arguments the function
- * should parse. If the optional arguments aren't found,
- * `null` will be passed to the handler in their place.
- * (default 0)
- * - infix: (optional) Must be true if the function is an infix operator.
- *
- * The last argument is that implementation, the handler for the function(s).
- * It is called to handle these functions and their arguments.
- * It receives two arguments:
- * - context contains information and references provided by the parser
- * - args is an array of arguments obtained from TeX input
- * The context contains the following properties:
- * - funcName: the text (i.e. name) of the function, including \
- * - parser: the parser object
- * - lexer: the lexer object
- * - positions: the positions in the overall string of the function
- * and the arguments.
- * The latter three should only be used to produce error messages.
- *
- * The function should return an object with the following keys:
- * - type: The type of element that this is. This is then used in
- * buildHTML/buildMathML to determine which function
- * should be called to build this node into a DOM node
- * Any other data can be added to the object, which will be passed
- * in to the function in buildHTML/buildMathML as `group.value`.
