as the slow convergence on a canvas-like model continues, i'd just
note in passing that it turns out to be quite useful in GnomeCanvas
for an item to be able to avoid ever being picked. this is possible by
inverting the logic of your patch, and asking each item ("widget")
whether a given (x,y) coordinate is within it. by returning false,
items can avoid ever being considered the target for an event. their
geometric bounds remain unaffected, of course.
