Rcpp too good to be true?
...my code, if someone has a minute to point out anything wrong
(or even if its correct and there is room for improvement, im pretty new to
this) it would be much appreciated. I've had a simple look at the results
and they look fine, but seriously, 500x faster?!

The major differences are:
1. Texture setup is different due to full NPOT support on nv40
2. More advanced blending/render targets on nv40
3. NV30 has fixed function registers, which NV40 lacks
The
