Well, GTK isn't setting the layer at all; that's a libgnomeui
function. libgnomeui = mostly kind of broken.

Though this particular thing works (it sets the layer), there's no
magic to handle dialogs or anything like that. Note also that the
layer hints are deprecated old cruft, replaced by the EWMH spec on
http://www.freedesktop.org, so this is not going to work long-term.

There isn't really a good (meaning, reliable across window managers
and situations) way to implement this. A recent proposal on
wm-spec-list gnome org adds a _NET_WM_TYPE_FULLSCREEN semantic type
which would solve the problem.
