Is Performer refusing?
This is part of Vanilla OpenGL 1.1. It may be that we erroneously rely
on the extension string being reported.
All recent and not so recent stystems should support this, heck even a
VGXT probably supports this.
What's your system?
What error message do you get?
What OpenGL version string & extensions does your server report? (Use
glxinfo on the command line)
Cheers,Angus.
