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.
