More graphics card notes:

I need to apologize to Matrox -- their implementation of hardware displacement mapping is NOT quad based. I was thinking about a certain other companies proposed approach. Matrox's implementation actually looks quite good, so even
if we don't use it because of the geometry amplification issues, I think it will serve the noble purpose of killing dead any proposal to implement a quad based solution.
