"""
This shows how to use the CFFI dynamic (ABI) binding. Note that is slower and more likely to run into silent errors and segfaults.
But it doesnt require any C compiler to build.

Previously this failed to work in the same place the ctypes binding fails, accessing
materials of a model. I though it was because Python can't dynamically tell the difference between a pointer and an array.
