Screenshot of wrong colors

When trying to run GTAVC on a i915 machine (this also affects Intel Atom N550,
since its GPU has similar architecture), the colors are messed up, and menu
screen is blinking.

I've tracked the problem down to lack of support of GL_EXT_vertex_array_bgra on
i915. I can reproduce it on my Haswell GPU by using
MESA_EXTENSION_OVERRIDE=-GL_EXT_vertex_array_bgra. (FWIW, i915 supports
GL_ARB_vertex_program, which might be used as a substitute. Although it's not
completely HW accelerated, but should be better than pure SW implementation.)

This game worked successfully with wine 1.5.9. I'll try to bisect wine to find
the bad commit, but apparently there've been lots of breakages with different
symptoms for i915 between wine versions 1.5.9 and 1.9.14, so bisection may be
unsuccessful.
