ray: libize raytracer core, introduces src/libs
This is the first step of breaking out all the core rendering stuffs
into reusable libraries and making modules purely compositional,
consumers of various included rendering/effects libraries.
Expect multiple modules leveraging libray for a variety of scenes and
such. Also expect compositions mixing the various libraries for more
interesting visuals.
