The POV macro feature is very useful, for recursion and commonly used
shapes, and saves time and code. The POv language is becoming more like
a programming language than a scene-description language. However, there
are limits to this language, first of all it is interpreted, secondly it
does not have many features of a normal programming language. I'm not
saying the POV-team should make a C++ compiler out of POV. My suggestion
is simply this: I think theres should be an integer variable type in
POV, it would take less memory than floats for many macro operations.
Also there should be some bit-fiddling functions for these, they would
be very useful for many operations, avoiding the int(mod(byte/4,2)) kind
of things that are cumbersome in both coding and parsing. Of course I
realize that POV is totally free and all, so if it's too much to ask,
fine.
