There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
Remove canvas->compositing dependency
There's one tiny place in the canvas crate that depends on the compositing crate, and it's really quite backwards. If we use trait objects instead it becomes much cleaner to reason about.

Upgrade WebRender
This is against an old Servo because I can't build current Servo due to compile errors in RNG crates. I verified that it starts up.

This factory will launch a GLPlayerThread from the application main
thread.
And add GLPlayerThread, the multiplexor for media players' video
renderers. This thread will receive commands from htmlmedialement
and webrenderer.
This code is also inspired by webgl_threads and WebGLThread.
Remove unused code (3/N)

Add initial support for WebGL compressed textures
This patch is an initial implementation of WebGL compressed texture support, it contains
- functions for registering and querying compressed texture extensions
- initial implementation of `CompressedTexImage2D` and `CompressedTexSubImage2D` and their parameter validation
- implementation of S3TC (DXT1, DXT3, DXT5) and ETC1 extensions as examples
What's still missing:
- some of the parameter validation steps are missing
- the pixel comparison tests fail for more complex cases (I'm probably missing something trivial at the GL calls)
