* \brief R300 Render (Vertex Buffer Implementation)
*
* The immediate implementation has been removed from CVS in favor of the vertex
* buffer implementation.
*
* When falling back to software TCL still attempt to use hardware
* rasterization.
*
* I am not sure that the cache related registers are setup correctly, but
* obviously this does work... Further investigation is needed.
