[Bug 34052] The Witcher: Character models are sometimes invisible

https://bugs.winehq.org/show_bug.cgi?id=34052

--- Comment #65 from Stefan Dösinger  ---
Because it's a problem in one game only, it is arguably a game bug, and because
the hack has the potential to cause a slowdown in all other games.

It would be nicer if we could get a semi-reliable 0.0 return from out of bounds
reads without an explicit range check - attachment 50908 is an attempt in that
direction, but it has other problems that are difficult to address.
