Do we need a RRProviderChangeNotifyMask? Can providers dynamically appear
and disappear? I assume they can due to things like USB hotplug.
I was wondering about this a bit more, I've added stuff in v5, to
notify off role
changes which seems useful, however I'm no sure how we notify of a provider
disappearing, it seems like it would be akin to an output/crtc disappearing
which we also don't support yet. I'm not sure if we should be sending
screen change
in that event, or we need a new RRScreenResourcesChangeNotifyMask, to provoke
a complete rescan.
Hmm, that's a good point. The server itself does support dynamically
creating and destroying outputs and CRTCs, but it looks like there's no
other event generated. I guess just punting on Provider events for now
is reasonable.
Keith, thoughts?
