+"""
+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.
