Quake Timedemo - 44fps!

With the latest driver optimizations and removal of a bunch of debug stuff from the usermode graphics library, I can hit 44ish FPS in a Quake timedemo. Given that the portion of the frame running on the hardware only takes about 10ms it should definitely be possible to get it running much faster, but there are still a number of potential bottlenecks and slowdowns due to having to access the device over the PCIe bus. Improvements to those portions of the stack are up next!
