"""
This is an attempt at a CFFI dynamic (ABI) binding. However, it fails to work in the same place the ctypes binding fails, accessing
materials of a model, because Python can't dynamically tell the difference between a pointer and an array. There's probably
some way to specify this (e.g. in raylib_modified.h) but it's difficult to be sure we fixed them all, and the errors
are often completely silent.
This shows how to use the CFFI dynamic (ABI) binding. Note that is slower and more likely to run into silent errors.
But it doesnt require any C compiler to build.
