The background work is definately non-negligeable. AllegroGL has way too 
much cruft dealing with fonts and video bitmaps. It's very ugly code 
that I'd really like to get rid of if I could help it.

As for emptying the pipe, no recent 3D accelerator will do that. Not 
only that, but even if a pipe flush is involved, rendering will still be 
an order of magnitude faster than Allegro's software routines.
