Partial texture clipping

[vvs-]

In some areas objects may share the space between its' polygons and surrounding room geometry. Thus it may occlude textures of such objects. One example can be seen in Caves setEntityPos(player,16791,87115,-8960,214,0,0). On a sufficient distance takes place visible flickering apparently caused by Z-fighting. This wasn't so obvious in the original game where camera didn't move during breath animation.

Another instance of apparent Z-fighting. It's visible only at a certain distance and angle. Note that it might depend on a particular driver and anti-aliasing settings.

Looks like the above grid Z-fighting was fixed for some reason. The only commit to suspect is 25c0de0, but I don't see why it should affect it. The original textures' Z-fighting is still present, of course.

Or it could be a coincidence. I've just updated some graphics related libraries 😉

Bisecting shows that it was in fact commit 1303ca6. Weird.

Those grid Z-fighting patterns actually correspond to wireframe patterns combined with frustum clipping. So, it's related to #65 too. Notice, how a change in the camera angle brings new patterns into frustum (bottom part of the picture):

@vvs- Just wanted to say, big thanks to your contributions to the project as a tester documenting bugs etc, it's awesome! Keep it up :)

Thanks. Apparently I have just too much spare time. 😔 At least somebody else can find something useful in my everyday disclosures.
