There is one little problem with lablGL:
The height functions provided for GlDraw.normal and GlDraw.vertex necessarely
uses boxed float.
You should add (I will do it for myself very soon) direct access to the GL
function to be able to benefit from the optimization of OCaml for unboxed float.
This is important for this two function and may be a few others (GlDraw.begins
and GlDraw.ends, ...) which are used very often and where the optional
arguments and the call to the stub code may cost too much.
But I think it is a good idea to keep a type-safe interface as much as possible
and put the unsafe fast call in a GlUnsafe module !
I learned GL using LablGl and it is very well suited for that. Much better than
raw C or C++.
