	* app/paint/gimppaintcore-stroke.c: cleanup.

	(gimp_paint_core_stroke_boundary): don't push a separate undo
	for each part of the boundary.

	* app/core/gimpdrawable-stroke.[ch]: added empty stub
	gimp_drawable_stroke_boundary(). Changed
	gimp_drawable_stroke_vectors() to take the GimpStrokeOptions as
	second parameter.

	* app/core/gimpchannel.c (gimp_channel_stroke): use it. No need
	to push an undo group around gimp_paint_core_stroke_boundary().

	* app/vectors/gimpvectors.c: changed accordingly.

	* app/widgets/gimpselectioneditor.[ch]: added a GimpStrokeItemFunc
	pointer and use it for stroking.

	* app/gui/edit-commands.[ch] (edit_stroke_selection): a
	GimpStrokeItemFunc which strokes the selection using the
	stroke-dialog.

	* app/gui/dialogs-constructors.c: use it for the selection editor.
