gnome-canvas: Change GnomeCanvasItem->point vfunc

Previously the function returned the distance to the nearest item. Now
it only returns an item that is hit. This slightly changes semantics
(button events are no longer dispatched to the nearest item, but only to
the item actually clicked on), but makes the code way simpler and
actually does what one would expect.
