First pass of rendering engine rewrite.
The (chickadee graphics gpu) module now handles most of the low-level
OpenGL object creation/deletion/binding. The (chickadee graphics
engine) module handles the with-graphics-state stuff via a render
context object. There's lots of stuff that isn't great, but it's the
first step towards a graphics backend agnostic rendering layer.
