void PEXFlushRenderer( Display *display, PEXRenderer renderer, int flush )
None.
Invoke PEXFlushRenderer to force all pending output to be either drawn or discarded.
If you set flush to True, then the renderer renders all pending output onto the drawable associated with the renderer. If you set flush to False, then the renderer discards all pending output.
If the renderer state is PEXIdle, then this function has no effect.
