Below idea is from danakj@ and enne@:
1a. Modify tests that create TestContextProvider from TestWebGraphicsContext3D to use TestGLES2Interface instead.
1b. Modify tests that query the TestWebGraphicsContext3D off TestContextProvider to use TestGLES2Interface instead.
* At this point tests no longer know about the TestWebGraphicsContext3D.
2. Merge functionality of TestWebGraphicsContext3D up into TestGLES2Interface and delete the former.
