Yeah, at some level, it would have been good to separate the device
configuration from the logical partition of the whole X screen into
'monitors'. One nice thing that would have easily allowed was the
creation of virtual 'monitors' for vnc or even DisplayLink. As it is,
we've managed (once again) to link a particular hardware interface to an
application capability. Sigh.

We do have such an abstraction today, called Xinerama, but it seemed
like the right plan was to deprecate that and encourage applications to
use RandR directly.
