[Bf-python] Added some GLU functions to BGL Module

Wed Jul 21 20:00:29 CEST 2004

Hello.

I have added 6 GLU functions to the BGL module.

Added functions are gluPickMatrix, gluProject, gluUnProject, gluOrtho2D,
gluLookAt and gluPerspective.

I had to add two new macros for wrapping the above functions.

Attached is the patch file for BGL.c, BGL.h and BGL.py
