Please, don't. 

With the current state of Haskell's openGL, all you need is the redbook
and a sed command that removes the 3f from vertex3f.

The most innovative feature that I witnessed is preservingMatrix
<io code> instead of pushMatrix(); <io code>; popMatrix();, but then
you could write a C macro to do exactly that. It's the same with
glBegin() and glEnd().

So, please, please, don't.

OTOH, all this vertex3f stuff and the difference between
glBegin(GL_QUAD) and glBegin(GL_POLYGON) is in some way a nice example
of expressing data using monadic composition.
