        USE(GLES2_RENDERING) will not be useful since we'll be coding to GraphicsContext3D
        instead of OpenGL and can use ENABLE(ACCELERATED_2D_CANVAS) for canvas 2d specific
        changes.  This deletes the macro and deletes the ChromeClient API to query
        GLES2Contexts since we'll never need one of these outside of the compositor, which
        is created in platform-specific code.

        Removes API support to grab a GLES2Context from within WebCore.  The compositor
        has a special codepath to grab its GLES2Context and no other codepaths
        need access to a raw context.  Accelerated drawing elsewhere will go through
        GraphicsContext3D.
