Terminal output in wine-1.3.4-202-g47d2a00

In wine-1.3.4-202-g47d2a00 introduction screen and fighting scenes in Melty
Blood are rendered upside down. These were drawn correctly in wine 1.3.4.

A regression test yields the following result:

    It breaks actual front buffer / back buffer flips.

Reverting this commit makes the screens be drawn correctly. Apparently this
game depended on the ddraw hack mentioned in the commit.

The biggest differences in error logs is that the terminal now is spammed with
many occurrences of:
fixme:d3d:context_apply_blit_state Applying blit state for an offscreen target
with ORM_FBO. This should be avoided.
