This is by no means a complete implementation, but I've slowed down on working on it, so I think we should look at what it takes to merge the current code. There are some major features missing, like initializing renderbuffers to 0 (uninitialized memory leak), tracking the attachments' attributes (width/height/format) for parameter requests, and lots of missing glCheckFramebufferStatus() validation. On the other hand, this is enough to run some demos using FBOs.

These new functions are derived from the existing uniform*fv
functions. They get used in a lot of demo code, so it should greatly
improve our compatibility.
This regresses uniformMatrixBadArgs.html, which gets at an existing
problem in our uniform matrix support (failure to validate
that the uniform is a matrix before calling down) but previously just
failed because it only called the 'fv' variants and never the existing
'f' variants.

- Please note the return value of the implementation, not sure about returning `false` on `InvalidEnum`.
- the `webgl/conformance-1.0.3/conformance/state/gl-enable-enum-test.html` wpt test is disabled on linux but was enabled on my machine and run to validate expectations.
- the `/webgl/conformance-1.0.3/conformance/context/methods.html` test is disabled everywhere. Enabling and running on my machine showed incorrect expectations beyond `isEnabled`. The test was temporarily edited to test just for `isEnabled` and it ran successfully.

There's one failure still, where a deleted program should still be
considered to be a program until it's unbound. However, I recently
made it so that we unbind at delete time, and we may need to partially
back that change out.

I have implemented ```TexSubImage2D``` follow [the spec](https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.8). This is my first version of implementation, and I notice I can reuse the code from ```TexImage2D```. Therefore, I would like to discuss make ```validate_tex_image2D_from_buffer``` and ```validate_tex_image2D_from_source``` to remove duplicate code.

This is a large-ish refactor of the Texture2D code, but it should be

Since it probably won't merge until multiprocess lands, I plan to use this PR to keep improving WebGL support until it can land.
Main TODOs are integration of tests, since it seems https://github.com/KhronosGroup/WebGL/issues/1105 is going nowhere, adding missing calls and proper painting via native surfaces instead of readback.
I can't resolve conflicts right now because of time but I will do it soon.

Currently, there are a few linting functions that only run on certain
filetypes (determined by the file extension). Prior to this commit, the
special cases were handled in a parent function with a conditional. This
commit changes the system so each linting function gets passed a
filename so the function can determine whether it should run or not
based on the file extension.
I also refactored flake8 linting slightly. From what I've read so far of
the code, flake8 itself will only print the results directly to stdout
(though the linter would report the quantity of errors detected).
Prior to this commit, we would let flake8 print directly to stdout and
just determine if there were >0 errors reported. This commit (sort of
hackily) temporarily captures stdout when we call flake8 so we can do
what we want with the output, allowing us to `yield` the line number
and message like we do with the other linting functions.
In my opinion, both of these changes isolate specific behaviors/checks
into their respective linting functions instead of having them handled
at a more global level.
In addition to the changes above:
* The whitespace linter now runs on WebIDL and TOML files
* The license header linter now runs on WebIDL files

This improves the encapsulation and consistency in our WebGL
implementation.
Also allows to implement new methods such as `getShaderSource()`.
It will also allow us to use `delete()` in the destructors of them (note
that we will probably want to keep track of them from the context before).
Some concerns:
**Trait method repetition**:
I'm aware that the traits `WebGL{Buffer,Renderbuffer,Framebuffer,Texture}Helpers` are basically the same, but `delete()` and `id()` methods are everywhere. I've thought something like:
```rust
pub trait WebGLIdentifiable {
type WebGLId; // id is sometimes i32 (see WebGLUniformLocation)
fn id(&self) -> Self::WebGLId;
}
pub trait WebGLBindable {
fn bind(&self);
}
pub trait WebGLDeletable {
fn delete(&self);
}
```
But I'd want to know your opinion first.
**`renderer` repetition**:
Thought of moving the field: `renderer: Sender<CanvasMsg>` to `WebGLObject`, but I think it makes it way more complicated to read, and also a bit unnecessary, at least IMO (`WebGLObject` will never interact with the field directly). It would also mean that all `WebGLObject`s should have one, which is true at this moment, but maybe not with WebGL 2, for example.

This commit implements:
* WebGLFramebuffer
* WebGLRenderbuffer
* WebGLTexture
And adds the following methods to `WebGLRenderingContext`:
* create{Texture,Framebuffer,Renderbuffer}
* bind{Texture,Framebuffer,Renderbuffer}
* destroy{Buffer,Texture,Framebuffer,Renderbuffer}
Fixes:
* WebGLUniform location shouldn't inherit from WebGLObject.
Known Issues:
* WebGL objects have to be destroyed on drop, we may want to keep a reference to the context, or maybe a clone of the renderer to achieve this
Also refactors a huge part of the current implementation, to allow
failing on creation of different WebGL objects.
Blocked on https://github.com/servo/gleam/pull/22

I couldn't add the `getContextAttributes` method since `CodegenRust`
doesn't know how to return a dictionary value, I'll take a look at it ASAP.
I think the helper functions can return directly the renderer, since they're used just for that, but I wanted to hear your opinions about this.
By the way I'm interested in adding more serious tests for WebGL, and I think the [khronos conformance suit](https://github.com/KhronosGroup/WebGL/tree/master/conformance-suites/1.0.3) should be the best option.
Should I try to integrate it in wpt, or making a `tests/webgl` directory (or similar) inside the servo tree? (Maybe this question should be for @Ms2ger)

@jdm @ecoal95 I'm working on making VR happen in the Browser and I want to bring to Servo the [webVR APIs](https://github.com/MozVR/webvr-spec/blob/master/webvr.idl) we already have in Gecko. Before anything happens we need a working implementation of WebGL (and also the [fullscreen API](https://fullscreen.spec.whatwg.org/)). My implementation is very basic and probably naive (I just recently started to contribute to Servo). My patch is just a starting point:
- It only implements ```clearColor``` and ```clear``` methods of the [WebGL spec](https://www.khronos.org/registry/webgl/specs/latest/).
- It uses the readback strategy that ```canvasRenderingContext2D``` is using (The webgl task paints stuff independently on it's own buffer and the compositor task request the pixels back to the webgl task when it needs them) I'm sure there are much better ways to handle this. Latency and FPS are critical in VR so we have to figure out the fastest way to push pixels to the screen. I've read something about layerizing the canvas but I'm still not sure what that even means :)
- There's an included test you can try ```./mach run tests/ref/webgl-context/clearcolor.html```
@ecoal95 I know you'll be working on this for the next three months. With a foundation in place we will be able to make quick progress in parallel. This is exciting!
