Hi. I'm trying to get an OpenGL 3.3 context using Pyglet. The pyglet code
only triggers on 3.2 and 4.1 version numbers.
Also, I have issue getting an nscontext. I sometimes get a None back. I can
get around the error if I don't ask for a shared context. I'm not sure this
is the right solution, as I don't really know what I'm doing. These are the
changes I made:
