[Mesa-dev] mesa compressed mipmap generation

[Eric Anholt]

Here's my series to finally fix compressed mipmap generation on hw
drivers.  Take a look at the last commit in particular -- I'd love to
do TexImage in the uncompressed path as well so we could get rid of
that awful code for handling this non-TexImage upload in the drivers,
but that would cost us the zero-copy for swrast.  Does anyone care?
