This implements the `canvas`, `drawingBufferHeight` and `drawingBufferWidth` getters to `WebGLRenderingContext`, and an initial version of `getParameter`.

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)

(or anybody, really)
This is just a simple version of summit3.html that has only the spinning rust logo and matrix multiplication calculator. Longcat currently has regressed and has both some rendering issues (margins have reappeared between the segments) and it only works as a standalone page and no longer within an iframe. I'll look into those enough to fix or at least log bugs when I get back.

Example output from the memory profiler:
```
| 1.04 MiB -- url(http://en.wikipedia.org/wiki/Main_Page)
| 0.26 MiB -- display-list
| 0.78 MiB -- paint-task # new output line
| 0.78 MiB -- buffer-map # new output line
```
The buffer maps aren't huge, but they're worth measuring, and it's good
to get the memory profiler plumbing into PaintTask.

* Add parser support for 3d transforms.
* Change ComputedMatrix to a representation that suits interpolation.
* Switch stacking contexts to use 4x4 matrices.
The transforms themselves are still converted to 2d and handled by azure for now, but this is a small standalone part that can be landed now to make it easier to review.
This puts the larger sub-trees first. E.g. this:
```
| 1.04 MiB -- url(http://en.wikipedia.org/wiki/Main_Page)
| 0.26 MiB -- display-list
| 0.78 MiB -- paint-task
| 0.78 MiB -- buffer-map
```
becomes this:
```
| 1.04 MiB -- url(http://en.wikipedia.org/wiki/Main_Page)
| 0.78 MiB -- paint-task
| 0.78 MiB -- buffer-map
| 0.26 MiB -- display-list
```
This matches how Firefox's about:memory works.
Now that this is done for all sub-trees, the ad hoc sorting done for
Linux segments is no longer necessary, and has been removed.
