FYI, freetype-py is entirely ctype-based, and my fontval-diag branch works in 
exactly that way - passing a function pointer in my extra python code to 
freetype-py to get diagnostic info out of freetype's truetype module. I looked 
up how to make it work and so it works that way (inherited from the Microsoft 
design where a function pointer get passed from the c# side of things into 
their proprietary font module).

I don't remember the details but it is just a few lines of python code. You can 
just diff my fontval-diag branch of Freetype-py against master to see how it is 
done.
