Add check for OpenGL version 2.1 on linux.
Unfortunately there's no easy way to show a messagebox here, so just
print a warning on fstderr and exit. If we don't call exit() here we get
crashes on other blender systems (python, opensubdiv) and it can get
tricky to track the initialization state here, so just using exit()
should do the trick for now.
