[q2x] DORIS: Math libs

[Nick Trout]

From: "Brian Hook"
> I know Doris has some primitive math stuff, but it's not all that, um,
fleshed out.  I posted to lua-l about this, and they don't seem to
know of any standard 3d math lib.  How do you feel about making one a
part of doris, or possibly even standalone?

I just wrapped the vector and matrix classes from GLUI since this works
pretty well with GL.

I'd suggest looking at Steve Baker's stuff?

Feel free to extend the functionality. What is missing?
