v2: Added benchmark results
Remove unnecessary _mesa_align_free in error case
Rename stride to width_bytes and make const
Remove mt->region->cpp from malloc size calculation
Remove misalignment from malloc size calculation
Chad: I think you're right about not needing misalignment in the malloc
size calculation, but if that's incorrect it could mean that the src/dst
buffers aren't coaligned and we'll get no performance improvement. Can
you double check that this patch still gives the expected improvement?
Elapsed time drops by -81.4861% +/- 1.22619% (n=3 s=14.9105, confidence=95%).
This patch has my r-b.
