Like I said before, I would need to use a custom layer 1.  This means that I
also have to write a custom layer 2 under both methods.  If boost::gui is to
be useful for me at all, it has to provide layer 3, and the interface
between layers 2 and 3 has to be public.

Oh, and I really want the ability to select layers 1 and 2 at runtime, in a
single place in my code, on a per top-level window basis.
