When Starcraft 2 is started menus have normal blue color, however when I start
a mission and then exit back to the menus, they are overbright (I'll attach
screenshots). Not the whole menu is too bright, background is fine, only the
user interface is too bright.

wined3d: Use EXT_texture_sRGB_decode to avoid sRGB texture duplication.

This commit won't revert from current git, however setting
MESA_EXTENSION_OVERRRIDE="-GL_EXT_texture_sRGB_decode" fixes this.

I'm using the r300g driver (b27f206b0cc9bf31bff6dd1abe66c4f21f3de21e), Kernel
2.6.38.2, RV530. I hope this isn't just some Mesa bug just uncovered by this
change however I don't see anything like this with NVIDIA.
