A while back Steve sent me something he had whipped up which he called
"xgl".  Basically you include xgl.h instead of gl.h and prepend an "x"
in front of all your opengl calls.  He then had things structured with
#defines so these could be translated straight to the real opengl
calls, or you could dump a log of the calls to console or file.

A modified version of this is part of the SimGear package:
