 // - RenderingHelper is charged with interacting with X11, EGL, and GLES2.
 // - ClientState is an enum for the state of the decode client used by the test.
 // - ClientStateNotification is a barrier abstraction that allows the test code
 //   to be written sequentially and wait for the decode client to see certain

Why GL_CLAMP_TO_EDGE vs. other settings?  
What happens with the new drivers if these are not set?
