Don't have that map :(

New patch at:
http://pdx.freedesktop.org/~anholt/dri/r200-projtex-8.diff

This one makes texgenmix work except for the bottom left corner.  The
problem was that we were using the complete texgen matrix, even if it
should only have been applied to specific coords.  Fixed that by using
rows of the identity matrix for set_texgen_matrix for disabled coords. 
Also, apparently q doesn't matter, so I removed the -1 for it.  Also, I
made GL_SPHERE_MAP a fallback since I never got texcyl to work
otherwise.  Does not fix doom3 lighting.
