| HostWebGLContext.h |
Host endpoint of a WebGLContext. HostWebGLContext owns a WebGLContext
that it uses to execute commands sent from its ClientWebGLContext.
A HostWebGLContext continuously issues a Task to the Compositor thread that
causes it to drain its queue of commands. It also maintains a map of WebGL
objects (e.g. ObjectIdMap<WebGLShader>) that it uses associate them with
their cross-process IDs.
This class is not an implementation of the
nsICanvasRenderingContextInternal DOM class. That is the
ClientWebGLContext.

| ImageBitmap.h |
ImageBitmap is an opaque handler to several kinds of image-like objects from
HTMLImageElement, HTMLVideoElement, HTMLCanvasElement, ImageData to
CanvasRenderingContext2D and Image Blob.
An ImageBitmap could be painted to a canvas element.
Generally, an ImageBitmap only keeps a reference to its source object's
buffer, but if the source object is an ImageData, an Blob or a
HTMLCanvasElement with WebGL rendering context, the ImageBitmap copy the
source object's buffer.

The purpose of ImageBitmapRenderingContext is to provide a faster and

then we'll transfer the surface of ImageBitmap to this context and then to
use it to display.

ImageUtils is a wrapper around layers::Image. It provides three unified
methods to all sub-classes of layers::Image, which are:
(1) GetFormat() converts the image's format into ImageBitmapFormat enum.
(2) GetBufferLength() returns the number of bytes that are used to store
the image's underlying raw data.
In theory, the functionalities of this class could be merged into the
interface of layers::Image. However, this is designed as a isolated wrapper
because we don't want to pollute the layers::Image's interface with methods
that are only meaningful to the ImageBitmap.

| QueueParamTraits.h |
QueueParamTraits provide the user with a way to implement PCQ argument
(de)serialization. It uses a PcqView, which permits the system to
abandon all changes to the underlying PCQ if any operation fails.
The transactional nature of PCQ operations make the ideal behavior a bit
complex. Since the PCQ has a fixed amount of memory available to it,
TryInsert operations operations are expected to sometimes fail and be
re-issued later. We want these failures to be inexpensive. The same
goes for TryRemove, which fails when there isn't enough data in
the queue yet for them to complete.
Their expected interface is:
template<> struct QueueParamTraits<typename RemoveCVR<Arg>::Type> {
// Write data from aArg into the PCQ.
static QueueStatus Write(ProducerView& aProducerView, const Arg& aArg)
{...};
// Read data from the PCQ into aArg, or just skip the data if aArg is null.
static QueueStatus Read(ConsumerView& aConsumerView, Arg* aArg) {...}
};

Usage:
===========
To create a new type from a set of GLenums do the following:
STRONG_GLENUM_BEGIN(TypeName)
STRONG_GLENUM_VALUE(ENUM1),
STRONG_GLENUM_VALUE(ENUM2),
...
STRONG_GLENUM_END()
where TypeName is the name you want to give the type. Now simply use TypeName
instead of GLenum. The enum values must be given without GL_ prefix.
~~~~~~~~~~~~~~~~
Important Notes:
~~~~~~~~~~~~~~~~
Boolean operators (==, !=) are provided in an effort to prevent some mistakes
when using constants. For example we want to make sure that GL_ENUM_X is
a valid value for the type in code like:
if (myNewType == STRONG_GLENUM_VALUE(SOME_ENUM))
...
The operators will assert that STRONG_GLENUM_VALUE(SOME_ENUM) is a value that
myNewType can have.
----
A get() method is provided to allow access to the underlying GLenum. This
method should ideally only be called when passing parameters to the gl->fXXXX
functions, and be used very minimally everywhere else.
Definitely XXX - DO NOT DO - XXX:
if (myNewType.get() == STRONG_GLENUM_VALUE(SOME_ENUM))
...
As that undermines the debug checks that were implemented in the ==, and !=
operators. If you see code like this it should be treated with suspicion.
Background:
===========
This macro is the first step in an effort to make the WebGL code safer.
Many of the different functions take GLenum as their parameter which leads
to bugs because of subtle differences in the enums purpose. For example there
are two types of 'texture targets'. One is the texture binding locations:
GL_TEXTURE_2D
GL_TEXTURE_CUBE_MAP
Yet, this is not the same as texture image targets:
GL_TEXTURE_2D
GL_TEXTURE_CUBE_MAP_POSITIVE_X
GL_TEXTURE_CUBE_MAP_NEGATIVE_X
GL_TEXTURE_CUBE_MAP_POSITIVE_Y
...
This subtle distinction has already led to many bugs in the texture code
because of invalid assumptions about what type goes where. The macro below
is an attempt at fixing this by providing a small wrapper around GLenum that
validates its values.
Comparison between STRONG_GLENUM's vs. enum classes
===================================================
The present STRONG_GLENUM's differ from ordinary enum classes
in that they assert at runtime that their values are legal, and in that they
allow implicit conversion from integers to STRONG_GLENUM's but disallow
implicit conversion from STRONG_GLENUM's to integers (enum classes are the
opposite).
When to use GLenum's vs. STRONG_GLENUM's vs. enum classes
=========================================================
Rule of thumb:
* For unchecked GLenum constants, such as WebGL method parameters that
haven't been validated yet, use GLenum.
* For already-validated GLenum constants, use STRONG_GLENUM's.
* For custom constants that aren't GL enum values, use enum classes.

@class WebGLImageConverter
This class is just a helper to implement WebGLContext::ConvertImage below.
Design comments:
WebGLContext::ConvertImage has to handle hundreds of format conversion paths.
It is important to minimize executable code size here. Instead of passing
around a large number of function parameters hundreds of times, we create a
WebGLImageConverter object once, storing these parameters, and then we call
the run() method on it.

Implementing WebGL (or OpenGL ES 2.0) on top of desktop OpenGL requires
emulating the vertex attrib 0 array when it's not enabled. Indeed,
OpenGL ES 2.0 allows drawing without vertex attrib 0 array enabled, but
desktop OpenGL does not allow that.

- '//' style comments include the initial '//' marker and continue up to, but
not including, the terminating newline.
- '/ * ... * /' comments include both the start and end marker.
- The begin comment delimiters (/ * or //) are not recognized as comment
delimiters inside of a comment, hence comments cannot be nested.
- Comments are treated syntactically as a single space.
