Hopeful fix

I think I finally got it. 

AFAIU, this is not really a regression, the patch just enabled a different
codepath in the game that triggered an existing bug. That is, our sRGB write
handling is not correct if blending is enabled.

Please try the attached patch on top of current Wine, removing the various
debug patches I previously attached to the bug. The patch probably still needs
some work (e.g. the WINED3D_RS_SRGBWRITEENABLE state handler maybe should be in
some other place, also it should take care of the other ffp backends) but it
should help anyway.
