ugh, i have some working code put together, i thought it
would be "nicer" to just cut and paste only what was needed
(and clean it up a little). here's a link to the .PY file
that works for me.
http://www.pygame.org/ftp/contrib/glblit.zip

if you are using pyopengl 1.5.6 or older, add a line "careful()"
after importing opengl, this will cause an exception to be
raised if any of the GL calls fail (rather than failing
silently as opengl does) if you are using one of the newer
SWIG version of pyopengl this does this by default.

anyways, the code should work for you as it does for me :]

yeah, that would be good. unfortunately SDL only supports
rendering opengl to the display surface. there's no way
to get an opengl context to an offscreen surface under SDL.
(although it sounds like a broken record, SDL2 is planned
to have support for this)
