	* libnautilus-private/nautilus-icon-container.c
	(finish_adding_new_icons): Do not place icons both in the
	no_position_icons and semi_position_icons lists!
	(snap_position): The final *x could be negative if (start_x + icon_width / 2)
	is less than SNAP_SIZE_X, as SNAP_NEAREST_HORIZONTAL() would
	return DESKTOP_PAD_HORIZONTAL.  Then, we would subtract icon_width / 2,
	getting a negative number.  So, we initially test for this and
	start that the first snap column.  The same reasoning applies to
	*y and the baseline.
