 // PerClientState --------------------------------------------------------------

 // CreateOutputSurface. SurfaceBinding obtains a pointer to the
 // PerClientState appropriate for the WindowTreeClient. PerClientState is
 // stored in a thread local map. When no more refereces to a PerClientState
 // remain the PerClientState is deleted and the underlying map cleaned up.
