I'd put the two widgets in a group, being sure to add them
in the order you want them to draw, then tell the group to redraw().
But if you find you sometimes want to switch which one draws
first, then you'd have to re-order them in the group, which
can probably be done with Fl_Group::remove() followed by
Fl_Group::add(),
or somesuch.
