[pygame] OpenGL: Fonts

[Kris Schnee <kschnee@xxxxxxxxxx>]

I did a condensed version of one of the font tutorials, making a version 
of it that worked for me. Unfortunately it doesn't seem to work now, 
because it complains: "ImportError: No module named win32ui." But this 
class might be useful as part of a font tutorial:

<code>

"""
RenderFont.py
Draws text on the screen in OpenGL.
Closely based on (ie. nearly ripped off from) a tutorial with the
following header:

Ported to PyOpenGL 2.0 by Brian Leair 18 Jan 2004
This code was created by Jeff Molofee 2000
The port was based on the PyOpenGL tutorial and from the
PyOpenGLContext (tests/glprint.py).
If you've found this code useful, please let me know (email Brian Leair
at telcom_sage@xxxxxxxxx).
See original source and C based tutorial at <http://nehe.gamedev.net>.
