	* app/core/gimpitem-linked.[ch]: made gimp_item_linked_get_list()
	and the GimpItemLinkedMask enum public. Hiding them just causes
	code duplication.

	* app/tools/gimpdrawtool.[ch]: added a GList of GimpVectors and a
	GimpMatrix3 transformation matrix for them. Just set them with
	gimp_draw_tool_set_vectors() and gimp_draw_tool_set_transform()
	and chain up in your tools's GimpdrawTool::draw() implementation
	to get the vectors drawn.

	* app/tools/gimpeditselectiontool.c: use
	gimp_item_linked_get_list() instead of traversing image->layers,
	->channels and ->vectors manually to find the linked items.
	Use gimp_draw_tool_set_vectors() and _set_transform() to show
	the linked vectors while moving.

	(gimp_edit_selection_tool_arrow_key): transform all linked items,
	not just the linked layers.
