heh.

in gtk+ 1.2, returning TRUE from a callback tells the signal system not
to propagate the signal to the parent class *after* all the handlers for
the current class have been handled.  or something like that.

in gtk+ 2.0, returning TRUE from a callback tells the signal system to
stop signal propagation right there.

in terms of correctness, the gtk 2 semantics are better, but it took me
a couple of *days* to figure out why some if my handlers were being
called and others weren't.  maddening, really.
