Working from memory, and after some experimentation, I found that the
glTexImage2D function in PyOpenGL appears to want a list of integers, at
least when supplied with the GL_UNSIGNED_BYTE constant.

Getting this sort of information from a QImage object at the Python level
appears to be difficult since there isn't an equivalent to the
QImage.loadFromData method for saving image data. Wasn't this problem
discussed on this list recently?
