da97483eee Switch to using 4-byte colours internally rather than floats 
These are stored in BGRA format so they can be directly cast to a uint32_t to get the
correct format for the argb param in pvr_vertex_t (yay endianess)

This results in a performance improvement as it reduces the data requirements.

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.
