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.
