#236 Segmentation fault by gluNewTess

[skrat]

Calling gluNewTess causes segmentation fault, due to call to glGetError. GLU tesselator doesn't need any GL context at all, so glGetError causes segfault on some platforms (GNU/Linux), or is silently swallowed by others (Darwin).

Test case:
from OpenGL.GLU import gluNewTess
tess = gluNewTess()
