fixed bug 5750, accepting drops by folders quirky at zoom levels below

	* libnautilus-extensions/nautilus-icon-dnd.c:
	(nautilus_icon_container_item_at):
	fixed bug 5750, accepting drops by folders quirky at zoom levels
	below 100%. The problem was that nautilus_icon_container_item_at
	was constructing a single pixel rectangle for hit-testing, that
	sometimes turned into a zero pixel rectangle when scaled down,
	depending on how things rounded off.  Fixed by using the
	canvas scale factor when building the rectangle, ensuring that
	it never becomes empty.
