	(create_selection_shadow),
	(icon_get_data_binder):
	Send outline rectangles for dragged icons off to a drag in a 100%
	zoom level scale.
	Scale outline rectangles in drag shadows using the scaling factor
	for the target view.

	* libnautilus-extensions/nautilus-list.h:
	* libnautilus-extensions/nautilus-list.c:
	(nautilus_list_get_cell_rectangle),
	(draw_cell), (nautilus_list_clear_from_row),
	(nautilus_list_set_drag_prelight_row),
	Make the call public, change the callers to pass NautilusList.

	* libnautilus-extensions/nautilus-list.c:
	(nautilus_list_each_selected_row):
	Add the row index parameter to the iteratee.

	* libnautilus-extensions/nautilus-list.c:
	(nautilus_list_get_initial_drag_offset):
