Commit 37b62cc35435a704d33c1814fbdbd0e807699e21 breaks 3DMark01 and flatout in
wine
- I915_LIE=1 (default) results in a black rectangle when 3dmark shows the logo
while starting, it's rendered correctly with I915_LIE=0
- I915_LIE=1 results in a solid color fill when using 32bpp and a 32bit zbuffer
in game test 1 (i haven't tried the other tests), choosing 16bpp or a 16 or
24bit zbuffer works fine. no rendering errors with I915_LIE=0
- flatout results in a solid color fill, no matter if with I915_LIE or without

all those solid color fills look like if it picks the rgb values of one pixel
at some corner.
