there are some opengl debuggers and tracers around - I'm googling for a
free windows one, mac users seem to have such support provided by apple, 
other platforms have their own. I don't have any experience with these, but
if they only show the opengl calls, it may be possible to compare the c and
haskell runs, especially where the hopengl version tries to mimick the opengl
version closely instead of introducing higher-level abstractions.

I'd be interested in recommendations, if anyone has experience with such
