import the new renderer and clean things up.

i integrated the renderer i've been developing
on the tinyrend repo and got rid of a bunch of
stuff that's no longer necessary. also began
structuring things to fit the new interface i
have in mind.

there are still some artifacts with the
projection xforms that cause issues with
clipping and division by zero.
