[PyQt] Opengl examples does not work on Windows

[Kamil Okrasa]

Hello all,

Long story short, none of PyQt5 OpenGL examples, except
openglwindow.py, work on Windows. [1] does not work either. The code
raises OpenGL.error.GLError, err=1282, invalid operation on every
PyOpenGL call.

I'm using Python 3.4.2 win32, PyQt5 5.3.2 and PyOpenGL 3.1.0 (with and
without _accelerate). Everything works fine on Linux with similar
setup. Examples also work fine in PyQt4 on both platforms. Any ideas?

Regards,
