Description
CGLCreateContext fails with error code 10009 when creating via WR from WebGL.
"Invalid share context. Two contexts are a bad match if their pixel formats use different renderers; this can happen if, for example, one format required an accumulation buffer that could be provided only by the software renderer, and the other format did not."
This causes Servo to fallback to a nice and slow alternative.

Research direction
No source file, test, or entry point is identified. Start by reproducing error code 10009 when creating a CGL context through WebRender from WebGL, then investigate the incompatible share-context pixel formats or renderers described in the report. Done means context creation succeeds without Servo falling back to the slow alternative.
