widgets on the canvas are second class citizens. don't go there.

all of GTK is slowly migrating toward a client-side compositing model
based on Cairo. do not expect the GTK crew to be supportive of any
attempts to fix up the existing canvas/widget dichotomy.

GtkLayout is the correct widget to use. But like all GTK containers,
it is not intended to handle overlapping widgets, although it can do
so under some circumstances.
