Fix android GL crash
There were two issues, fundamentally:
1. POINT_SPRITE is not supported on GLES, which was causing the GL_INVALID_ENUM error when using any WebGL API.
2. The version check was using the wrong version value to determine if enabling point sprites was necessary.

Use pixels::get_rect in CanvasData::draw_image

We use that to send only the pixels that will be actually drawn to the
canvas thread in CanvasRenderingContext2d::PutImageData.
We also make the canvas thread byte swap and premultiply colours in-place.
Optional backtraces for JS errors and WebGL errors
This adds two new build-time features to enable useful debugging tools when investigating why JS and WebGL content isn't working. They're optional because they're quite heavyweight.
