Textures not power of 2 fix

NOPOWER2FIX

Some games don't properly check whether the hardware can properly manage textures whose sizes are not a power of 2 (e.g. 16, 32, 64, 128 bits). If textures of a different size are processed by hardware without this capability, you get diagonal effects on the rendered image. The option fixes this problem.

ZBUFFER0CLEAN

Some games don't properly clear the zeta buffer between frames, producing incorrect surface z-ordering and other issues. This flag fixes this problem.

Clean ZBUFFER @1.0 fix

ZBUFFERCLEAN

Some games don't properly clear the zeta buffer between frames, producing incorrect surface z-ordering and other issues. This flag fixes this problem. It is similar to ZBUFFER0CLEAN, but it works in different contexts.
