	* libgimp/gimpmenu.c (gimp_image_menu_new): call the callback with
	the selected image which is not necessarily the requested one
	(fixes bug #92586).
	Also changed all menu constructors to always call the registered
	callback even when the value is -1 because the menu is empty.

	* app/gui/plug-in-commands.c (plug_in_run_cmd_callback): run the
	procedure even if there's no active GIMP display. The display and
	screen is then taken from the current cursor position.

	* app/gui/gui-vtable.c (gui_get_display_name): don't call
	gimp_display_get_by_ID() unless gdisp_ID is > 0.
