Help needed to update our use of OpenGL

[John W. Eaton]

I would like to update Octave's use of OpenGL so that it avoids 
deprecated OpenGL features but I have little real experience with OpenGL 
programming and could use some help.

As I understand it, these changes will primarily involve migrating from 
"immediate mode vertex attribute specification" (code starting with a 
call to glBegin ending with a call to glEnd) to using vertex 
array/buffer objects and modifying the way lighting is handled.

Are there any experts out there who could help with this job?
