Yes, this subdivision is a nice feature that Gnome's canvas has that
Tk's canvas doesn't.  I'd (independently) thought of doing this for
Tk's canvas, to make it feasible to build hierarchical list widgets in
the canvas (the advantage over a special widget is the extra
flexibility you'd get).  Perhaps I'll get around to trying it
sometime.
