creating a scalable icon. Instead it should be possible to get a
	scalable icon and then get either an anti-aliased-optimized or
	non-anti-alias-optimized version of the icon.

	* libnautilus-extensions/nautilus-bookmark.h:
	* libnautilus-extensions/nautilus-bookmark.c:
	(nautilus_bookmark_get_pixmap_and_mask): Pass FALSE so we get the
	non-anti-aliased version.
	(nautilus_bookmark_get_pixbuf): Add parameter to indicate if we
	want the anti-aliased-optimized version or not.
	(nautilus_bookmark_update_icon): Get rid of anti-aliased boolean
	here since we are just updating the scalable icon.
	(nautilus_bookmark_set_icon_to_default): Get rid of anti-aliased
	boolean here since we are just updating the scalable icon.

	* libnautilus-extensions/nautilus-icon-container.c:
	(nautilus_icon_container_update_icon): Pass in a flag to indicate
	if we need the anti-aliased version of the icon or not.
