	* app/gui/dialogs-commands.c (dialogs_create_dockable_cmd_callback):
	accept a list of dialog identifiers and try to raise an existing
	dockable from the list. If that fails, create a new one from the
	first entry.

	* app/gui/image-menu.c
	* app/gui/toolbox-menu.c: specify alternative dialog identifiers
	where appropriate.

	* app/vectors/gimpstroke.c (gimp_stroke_interpolate): use NULL
	instead of 0.
