Hi,
Yes, I already used gnu-libplot that already does what g2 does (don't know 
exactely about g2), but I actually decided to use gtkDPS which is much more
powerful that any multi-format emulation engine. 

The reason why I was wondering about Mesa 2D quality was that the main drawback
of using a 2D lib (as DPS for instance) is that you must rewrite all 3D 
routines.
Or you have to separate 2D graphs from 3D graphs.

About the OpenGL->postscript, I can't figure out how you could translate
openGL texture mapping to postscript.
