hack to improve performance greatly

Aliens vs Predator 2 game (DirectX8, I think) is slower in wine by a factor of
5-10 at least, often giving seemingly just a few fps even on lowest settings
whereas on windows it runs great on highest settings. Basically unusable.

The cause is certainly this:

fixme:d3d_draw:drawPrimitive Using software emulation because manual fog
coordinates are provided

I'm sure because a hack that disabled this software emulation makes the game
run in much more acceptable speed. I'm at the moment unaware what side effects
it causes, but the game looks mostly allright with it (I didn't manage to go
beyond the very first room though because of mouse input bug).
