The purpose of the following two patches is to make st/mesa expose the S3TC
extensions when the force_s3tc_enable environment variable is used. This is
to match the behavior of the DRI drivers, in which force_s3tc_enable is an
option in driconf. Although st/mesa can't use the driconf functions, it can
at least respect the environment variable for this option.
These patches have been tested with fs2_open 3.6.12 and the Freespace 2
MediaVPs. Setting force_s3tc_enable=true makes the game run flawlessly
without libtxc_dxtn, whereas without it the game writes several error messages
to its log file and then crashes.
Which driver(s) did you test this with?
I'm wondering if we could just add the force-enable code down in the
util/format code and let it percolate up to the state tracker. I
haven't looked at this in detail yet.
