	General fix for bug #478657:

	* libgimp/gimpaspectpreview.c
	* libgimp/gimpdrawablepreview.c
	* libgimp/gimpzoompreview.c: let all preview widgets store the
	state of the Preview toggle. Declared "toggle" parameter as unused.

	* plug-ins/common/*.c: pass NULL for "toggle" to
	gimp_drawable_preview_new() and gimp_aspect_preview_new().
