Ok, cool.  I thought GL was generally designed to completely hide the 
frame buffer from the application; certainly the original SGI hardware 
didn't let the CPU touch it directly.

I do need an X server for complete X semantics, including window management
and interclient communication.  As such, redirecting rendering from
applications through the X server and thence to GL provides a very
straightforward development path.  We've tried direct rendering with 2D in
the past many times and haven't found it useful, but perhaps we will want
to try again once X itself is better integrated into a direct rendering
framework.

Besides, the X server will still be needed for remote application 
rendering, just as it does with GLX today.
