--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The problem is that it creates a mip-mapped compressed texture (DXT1) and
copies in each level. However DXT1 has a block size of 4x4, so mesa refuses to
copy in the last 2 levels. I need to go back and look at the spec, but I
believe that's bogus behaviour... we should be allowing this.
