Hi René,

I have now written a little C extension to wrap, and openGL calls have 
almost disappeared from the profile : openGL calls went from 11.89 % of 
the total time in the previous profile, down to 1.84 % with the C 
extension ! I have kept the whole initialization in pyopengl since it's 
not as performance critical. Thanks for your sound advice !

Best regards,

Timothée
