Yes; I understand that. But then rest of Emacs does not look much like
the Gtk anyway, it's a win-loose.

I was mostly proposing for "pure Emacs" frame, special buffer or not, I
don't know. Why not?

That makes implementing "sticky" tooltip as someone suggested quite
trivial.

There is only one tooltip active at a time (I think), so there is just
one buffer/frame needed; and tooltip text could be erased/set when a
tooltip is shown. Would that be too inneificient?
