[Oberon] Hardware 3D Acc.

What about the Permedia 2?  That 3D chipset has
been supported in Native Oberon before BlueBottle
was released.  There was also writtena 3D graphics
language called OGL that was designed to be
portable, but only works with Permedia 2 at theis
point.  As for the specs of graphics cards not 
being available, that's only partially true.  
Thanks to Linux the source code for many 
advanced graphics cards such as the NVidia 
chips are freely available.  Now the problem 
is you have to wade through thousands of lines 
of ugly C code just to figure out what could 
have likely been documented in a few pages of 
plane text.  I've downloaded the NVidia code 
myself, but I haven't taken the time
yet to seriously look at it.  Is anyone else
interested?  If BlueBottle had drivers for 
NVidia and ATI chips it would be well 
positioned in the 3D graphics arena.
