Two questions: first, what's with the excessively long names, and second, why is it so important for these to be stored as global variables? I have a hunch that a LOT of your global variables would be much better off in objects.

You would rather deal with a cluttered mess of global variables than organize them into classes and namespaces, just because you don't like to have to put the namespace or object name before the variable you're referencing?
Huh?
Do whatever you want, but seriously, this is just a silly complaint and tells me you haven't even TRIED to use object-oriented programming.

I looked at it, and like I expected, it was a terrible mess, not a good example of whatever it was attempting to do.
Out of curiosity, how long have you been programming, and what languages have you used?
