Incorrect face culling causes major graphical glitches.

Final Fantasy XI is suffering major graphical glitches because triangles are
culled incorrectly.

Disabling the two calls to glEnable(GL_CULL_FACE) in
"wine/dlls/wined3d/state.c" makes the glitches disappear and the game is
rendered perfectly.

I first observed this in the Debian/testing build (1.8.5-1) and also found this
to be the case when building 1.9.22 from source.

I used the Debian Linux kernel linux-image-4.7.0-1-amd64, as well as a
self-compiled 4.9.0-rc3 with Mesa 12.0.3.

GPU: "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"

The graphics flicker a lot when moving the camera even slightly, i.e. suddenly
other triangles get culled.

I'm not using any library overrides.
