Well, I told Afterstep to make the app 'NoTitle, NoHandles,
WindowListSkip, StaysOnTop, Sticky'.  So the main window is mapped with no
decorations, which is what I want.  However, my subwindows which need
decorations are simply set to a different wmclass with the
gtk_window_set_wmclass (I think) function, so the window manager sees them
as different from the main window, so it figures it should map decorations
for them.  I haven't tried this outside of Afterstep yet, but I plan to
test it with AS, windowmaker, Enlightenment, FVWM (orig, 2, 95).  I figure
that the fvwms at least should work pretty much the same as Afterstep,
since they share common code.  I haven't used Enlightenment very much,
though, so I'm not sure how it will react to it.
