	* app/display/gimpstatusbar.[ch]: added gimp_statusbar_peek(), a
	method to access the contents of the statusbar.

	* app/display/gimpdisplayshell.c
	(gimp_display_shell_window_state_event): when the iconfied state
	changes, call gimp_display_shell_progress_window_state_changed().

	* app/display/gimpdisplayshell-progress.[ch]: when the image
	window is iconified, display the progress message in the window
	title so that it appears in the task bar.

	* app/menus/plug-in-menus.c: formatting.
