[Fresco-devel] questions on OpenGL acceleration for Berlin

To get Berlin to use OpenGL hardware acceleration
is it necessary to run it on top of SDL on X (or
X DGA)?  Is this what SDL/GL is about?

Will we ever see OpenGL acceleration independent
of X?

Is DRI independent of X?  If it is and if Mesa is
committed to using DRI for hardware acceleration,
then wouldn't it make sense to run Berlin on top
of pure Mesa running on DRI drivers?

Also what about using DirectFB and OpenGL/Mesa on 
DirectFB?  Does this make any sense?
