ae335eeff1 Large refactor of vertex submission
This should be much faster as matrix loading is now minimized. Also splits transform from perspective divisionn
to lay the groundwork for near-z clipping. This also fixes GL_POLYGON submission.

Lighting can be made faster, this doesn't change the lighting algorithm, but the matrix changes should speed things up.
