Yeah, I use it also, but it would be good to have an example with the
official code. In particular the bit about making extensions work is
probably not obvious (and missing from that post I think. For the
record, the magic bit (as of the last time I tried it) is to add (setf
%gl:*gl-get-proc-address* 'sdl-cffi::sdl-gl-get-proc-address) after
the GL context is valid, and before you call any extensions).


>  As far as CLX is concerned, cl-opengl doesn't work with that, does it? I seem to recall some discussion about this (on IRC maybe) but I don't really remember so I could be wrong. Any further information on CLX + cl-opengl would be appreciated by me as well.

Not sure about that, I've heard that it should work, but I haven't
done any X coding in long enough that I don't know whether I would
expect it to work or not...
Either way, it would be nice to determine if it works or not, and
provide examples if it does, or document it if not
