[Mesa-dev] [PATCH 0/2] Make Gallium drivers respect the force_s3tc_enable environment variable

[Bryan Cain]

This is a revised version of my previous patches.  Patch 1 incorporates
Brian's feedback, and patch 2 is unchanged from before.  I did test patch 2
without patch 1, and found that both patches are neeeded for force_s3tc_enable
to work.

Both of these are candidates for 7.10 and 7.11, since games such as 0 A.D.
expect drivers to support this.
