// once per frame, which eliminates the possibility for inter-frame
// overdraw optimization. Furthermore, in cases where immediate mode is
// required multiple times per frame, the repeated flushing of deferred
// commands would cause significant overhead, so it is better to just stop
// trying to defer altogether.
