This is MUCH better!

One quick thing though: can we get the return types on the line above 
the function def?  We have some pretty unwieldly names (check out 
glx.h... it has some nasty ones).  That might help remove clutter.

I was also thinking if there was a way they could be grouped better like 
by request/reply or maybe the iter functions grouped together.... not 
sure though, that might not work.  Anyways, much better thanks!
