Running pynsource under python 3.10 needs ints not floats to all OGL calls

I've fixed most of these, but here is another.

Traceback (most recent call last):

Looks like a problem with the wxPython OGL module - see wxWidgets/Phoenix#2349.

May have to work around this by bundling a local copy of OGL.py with the required float to int fixes.
