Not for long now, hopefully...

Again, no argument here - the clcd-specific properties will be of use
whatever happens in the future (the "immediate" display timing subnode
is optional and is cloned from other existing bindings, so no new
problem is introduced here). I'm just shying away from the discussions
on generic display (or CDF or video or whatever) bindings. Call me
coward if you wish (maybe just tired to death with this subject ;-)
