Updated R5xx 3D Programming Guide

[Alex Deucher]

AMD has released a updated version of the R5xx 3D programming guide.
The new version offers expanded coverage on texture memory layouts,
some notes on implementing anti-aliased lines/points/polys, and some
additional registers.  The new version of the document is available
here:

As usual, if you have any development related questions, let us know.

Thanks,

Alex
