* SWIG outputs two files - renderdoc_python.cpp with the main actual
wrapping code, and renderdoc.py a small module that does some
bootstrapping on python side.
* We use a custom version of SWIG that generates strong/typed enums in
python based on enum classes, so in cmake we add this custom swig
fork as an external project and compile it before generating the
wrappers. On windows there's a committed version of the SWIG binary
that gets run directly from the .pro or .vcxproj.
* The renderdoc.py gets embedded as a resource on windows or as a C
generated unsigned char array via include-bin on other platforms, so
that we can insert it into the python context without needing it to
sit around on disk somewhere in sys.path
