Christoph Oelckers 79a0f76801 - replaced TexMan.operator() with two functions. 
This was done to make reviewing easier, again because it is virtually impossible to search for the operators in the code.

Going through this revealed quite a few places where texture animations were on but shouldn't and even more places that did not check PASLVERS, although they were preparing some paletted rendering.
