Hi Daniel,

This looks really good.

Couple of issues I had when trying to build on my system

cabal: At least the following dependencies are missing:
OpenGLRaw >=3 && <3.2, singletons >=1.0 && <2.1

I have

OpenGLRaw-3.2.0.0
singletons-2.1

However when I went into the cabal file and replaced "<" with "<=" that didn't seem to make the build happy.  Also, since you used "<" specifically I thought there might be a good reason for that.
