Well, I guess one day I'll have to import Mesa's BeOS driver under haiku SVN,
But maintaining in two places is not fun :-(

Hum, no ;-)

Mesa's BeOS port is source and binary compatible with Be's libGL.so, so I don't
seem why we could not be compatible from Haiku too ;-)

Maybe it was about being compatible with the Beta OpenGL Hardware accelerated
version? I can't see how we could be, as:
- it was never made public API (but it'd leaked...)
- it make no sense at all ;-)
- better to do our own new, public, open sourced API for Haiku/BeOS OpenGL
accelerant add-ons.

I've started to work on this last point, BTW.
Currently, on my laptop, I've a libGL.so which contains exporting BGLView class,
the gl and glu calls BUT not the renderer.
I'm working on porting the Mesa BeOS driver into an addon (accelerant/opengl/*
?) so the current Mesa-based software renderer will come as an addon.
