2018-03-19ray: libize raytracer core, introduces src/libsVito Caputo
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.
