I'm just about to commit to fairly large updates to the intel driver
that offers rotation support fully accelerated with 3D as well.

One of the problems that surfaced in this was the dri layers own mapping
of the front buffer which we ended up working around by mapping a 0
length one for now.

But the next logical step is to remove this mapping from the DRI layer
and leave it upto the drivers to map it just as if it were a back or
depth buffer.

Any objections or comments on this, as it may well break binary drivers
that depend on the DRI mapping it ??

Alan.
