Resolution we now can handle using randr.

Depth has been a real problem: we believe it would break most existing
applications (particularly Xt or Motif applications, if we had tried to
do it the way we first envisioned in randr, and then backed away from.

But composite makes depth switching easy: the applications don't have
their depth changed out from under them, and only the compositing
manager has to do anything.  So we should be able to handle this pretty
well once composite is the "normal" way most people use X.

We have lots of work to do for handling outputs and for mode setting in
general.  But this should be (mostly) something that most applications
don't have to care about.
