Yes.

That wokuld be...bizarre.  That's what Expose events are for; drawing
based on MapNotify is pointless.  If there's anything to draw to
(screen or backing-store), an Expose will be coming along soon for it
(or has already arrived - I can't recall whether there's a constraint
on the ordering of MapNotify and Expose events from a single
occurrence), and if not, there's no point in drawing.

Actually, the window manager (or session manager) is what maps and
unmaps them; this isn't something the WM has to ask the client to do.
(Well, not in X.  As mentioned before, in a hybrid system like OS X,
non-X clients may of course operate with non-X semantics.)

If they get mapped and unmapped at all, of course; as you mention,
off-desktop windows are sometimes just moved off-screen instead of
being unmapped.
