Patch

I had a look at this: it's a fog issue, actually the same as bug 27733. I'm
attaching a patch that fixes the bug for me.

Notice that the fix only affects the GLSL vertex replacement pipeline, so you
won't get the new behavior if you aren't using it (because of UseGLSL =
disabled or a very old GPU, mostly).

I think this patch may be a bit too risky for Wine 1.6 so I'll probably wait
for the release before submitting it.
