* fix a few bugs related to 2D GPU registers (so there are atleast some of the graphics tests that pass)
...
* less shitty texture mapping (and perspective-correct interpolation in general). extra bonus is that it also takes less divisions.

keep the GPU from crashing if there's no VRAM mapped, I guess.

noting that the way it's accessing VRAM is grossly inaccurate.
