glade-xml is not much good, because the widgets most plugins want
don't exist in standard GTK+. that means you have to do a bunch of
work to add new widgets to glade's view of the world.
hence the proposal to use XML with the LADSPA-GUI DTD. this leaves the
backends (which convert XML into real, native widgets):
1) simple (no generalized glade-like handling)
2) toolkit-neutral (though any particular backend obviously
is bound to a particular toolkit)
