Please add Varjo

Varjo contains a lisp->glsl compiler

Translates a subset of common lisp to glsl. Checks types and allows rolling translate where args and uniforms from one stage are made available in the next.

Support ubos, external struct definition & is easy to extend

git@github.com:cbaggers/varjo.git

Thanks :)

[note] Does depend on 'fn' another library with a quicklisp add request.
