Hej,

this all sounds really cool :-)

I hacked a little bit of code to generate C bindings for what is specified in
the glcorearb.h file. I also wrote a small script to extract the gl constants
and define them as scheme variables.
This is all *really* hacky stuff, but if somebody wants to have a lookt at it...

I did use r6rs bytevectors (bytevector-ieeee-single-native-ref...) to plow
through my data and it was rather sluggish. It's quite possible that I did
someting terribly wrong, but I went back to do the crunching in C...

Looking forward to have a look at your code :-)

Happy Hacking,
