 // The bulk of this file is support code; sorry about that.  Here's an overview
 // to hopefully help readers of this code:
 // - RenderingHelper is charged with interacting with X11/{EGL/GLES2,GLX/GL} or
 //   Win/EGL.
 // - 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
 //   state transitions.
 // - GLRenderingVDAClient is a VideoDecodeAccelerator::Client implementation
 // - Finally actual TEST cases are at the bottom of this file, using the above
 //   infrastructure.
