	* libgimpwidgets/gimpcolordisplaystack.h: forgot to declare
	gimp_color_display_stack_clone().

	* app/display/gimpdisplayshell.[ch]: replaced the GList of
	GimpColorDisplays by a single GimpColorDisplayStack.

	* app/display/gimpdisplayshell-render.c
	(gimp_display_shell_render): changed accordingly.

	* app/display/gimpdisplayshell-filter.[ch]: reduced API to a
	single function, gimp_display_shell_filter_set(), which exchanges
	the whole filter stack. Idle update the display on
	GimpColorDisplayStack::update().

	* app/display/gimpdisplayshell-filter-dialog.[ch]: changed
	accordingly.  Return the created dialog instead of assigning
	shell->filters_dialog.

	* app/gui/view-commands.c (view_display_filters_cmd_callback): set
	shell->filters_dialog here and raise it it if already
	exists. Don't use the dialog factory to create it because it's a
	transient dialog for the display which does not need to be session
	managed.

	* app/gui/dialogs-constructors.[ch]
	* app/gui/dialogs.c: removed display filter dialog stuff.
