[wxPython] wxGLCanvas

I'm playing with the wxGLCanvas stuff just to learn how to use GL
inside wxPython.

i've tried the wxGLCanvas.py that came with my python-wxwin docs
(examples directory), and it didnt work (screen stays blank), found
that the 2.1.16 had updated the file, tried that, and still the screen
stays blank.

i found some stuff on the wxpython-users mail archive on this topic
from Dec 1999, tried that, and still get blank screen.

is this a known problem? yes, i added EVT_PAINT where appropriate.
OnPaint IS indeed being called, just screen stays blank (black).

many thanks...
