pass an fd through the compositor to the other client and let them
sort it out?
+ - DnD issues:
+
+ How to roboustly handle failing drag, ie the case where an
+ application gets a button event, tries to activate a drag, but when
+ the server gets the drag request, the button has already been
+ released and the grab is no longer active. What's the concern:
+
+ - Application may set a drag cursor that doesn't revert back,
+ since a failed drag doesn't result in a pointer_focus event to
+ give focus back to the surface. We could just do that: if the
+ pointer_focus is the same surface as we tried to start a grab
+ for, just remove and give back pointer_focus.
+
+ Alternatively, set drag cursors only in response to drag events,
+ like drag focus. But drag_focus and drag_motion are sent to the
+ drag target, so the source surface won't always get those. We
+ may also end up setting the cursor after the drag ends, but in
+ this case the drag started and ended and we'll get a
+ pointer_focus event, which will make the application reset the
+ pointer image. Could introduce a drag start event that
+ indicates that the drag active.
+
+ How to handle drop decline (accept with type=NULL)
+
+ - Targets must send a NULL type in accept if they don't accept a
+ drop at the drag_focus/drag_motion position. Root window will
+ send a NULL type or x-wayland/root-something type if the source
+ offers that.
+
+ Races between pointer motion, ending the drag, the target sending
+ accept request and the source receiving the target event.
+
+ - We've sent a drag focus or motion event to the source, but
+ haven't received an accept request corresponding to that event
+ and now the button is release. The compositor could wait for
+ the source to reply to outstanding focus/motion events before
+ sending the finish event to the source. Or we could send the
+ finish event through the source so that it needs to reply to the
+ finish event too. Either way, the state of the drag blocks on
+ the client. What if we drag to a client that doesn't doo dnd?
+
- copy-n-paste, store data in server (only one mime-type available)
or do X style (content mime-type negotiation, but data goes away
when client quits).
+ - Optional pointer images.
+
- Discard buffer, as in "wayland discarded your buffer, it's no
longer visible, you can stop updating it now.", reattach, as in "oh
hey, I'm about to show your buffer that I threw away, what was it
