I've had a look at backporting this fix to r300c myself because I suspect that
it's one of the very last bugs keeping WoW "second rate" on Radeon hardware
with classic Mesa. (Gallium would currently be unplayably slow, even if it
didn't crash first...) However, while the fix seems conceptually described as
"calculate a texture cache region and set these bits in the texture format, I
cannot even begin to identify which are the corresponding parts of the r300c
code that would need to be changed in order to backport the fix correctly.

So I'm asking again: can someone please backport this fix into classic Mesa? It
would seem like an obvious candidate, because it's a genuinely identified
problem that users in the Real World are actually hitting, and where using
Gallium instead is simply not possible.

Thank you.
