Well, RRScreenChangeNotify is supposed to signal any 'screen
configuration changes', which presumably includes adding or removing
crtcs or outputs...

However, something a bit simpler, like a global event that reported when
the available resources changed might be more useful for applications


	window: WINDOW			window requesting notification
	time: TIMESTAMP			time property was changed

	This event is reported to clients selecting RRResourceChange
	on the window and is generated whenever the set of available
	RandR resources associated with the screen has changed, either
	created or destroyed. Querying the list of available resources
	with RRGetScreenResources will return the new set.

We could get really fancy and add Create/Destroy notifiers, but I don't
think it's all that important...
