	* app/core/gimpdrawable.c (gimp_drawable_sync_source_node): need
	to rip the floating selection's source node out of its layer's
	graph before using it in the floating selection sub-graph, and
	need to plug it back there when it's not a floating selection any
	longer.

	Unrelated:

	Also introduce a "fs_crop_node" that makes sure the floating
	selection stops at the drawable's boundaries.

	(gimp_drawable_visibility_changed): use item->node instead of
	gimp_item_get_node() because the latter creates the node on
	demand.

	* app/core/gimpdrawable-private.h: add fs_crop_node member.
