Instead of:
pixel = ord(pixel[0]), ord(pixel[1]), ord(pixel[2])
Try this:
pixel = pixel[0][0][0],pixel[1][0][0],pixel[2][0][0]
Python 3 handles strings much differently from Python 2. I suspect PyOpenGL
was changed, intentionally, to make this string functionality consistent
across Python versions.
