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.

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.

The expectation change is due to the shader now using its DOM-side compile status.
It is actually a bug for the shader to think it actually compiled successfully,
but at least it does so consistently now.
