[Mesa3d-dev] FetchTexel and new texture format/utility code

[Gareth H. <ga...@va...>]

I really like the way this has come together.  I'm just filling out the
FetchTexel routines for the non-standard formats at the moment, but all
in all I think the texture image handling is much more driver-friendly. 
This, combined with the changes to the DD API for Tex[Sub]Image*, means
that texture state and image handling will be cleaner and certainly more
efficient where hardware drivers are concerned.
