	* app/core/gimpitem.[ch]: added "const gchar *stroke_desc" to
	the GimpItemClass struct and always push an undo group
	around GimpItem::stroke().

	* app/core/gimpchannel.c
	* app/core/gimpselection.c
	* app/vectors/gimpvectors.c: set the stroke_desc accordingly
	and don't push undo groups.

	* app/text/gimptextlayer.c (gimp_text_layer_class_init): set
	all of GimpItemClass' undo_descs.

	* app/text/gimptextlayer-transform.c: don't push undo groups here.
