     GNOME version: ---

Extends the API in a backward compatible way where the caller can call export
multiple times, getting the same exported handle.

For gtk4 we should consider changing the API some how. For example adding a
handle to the unexport means we can export the same surface multiple times with
unique handles. If we add a intermediate object, we can add the abilitiy to
unexport before having received the handle (though this would of course make
the API more complicated).
