while ToggleRulerVisibilityAction was both added to contextmenu  and workbench menu,the state of  ruler menuitem can't disppear properly 
the reason is  because of the methods isChecked() and run()
when the ruler  menuitem in contextmenu was clicked twice,the state of menuitem
is different from the GraphicsViewer  PROPERTY_RULER_VISIBILITY property
advise :
the method isChecked() shuld not be over written
the method shuld beover written as below
	public void run() {
		diagramViewer.setProperty(RulerProvider.PROPERTY_RULER_VISIBILITY,
				new Boolean(isChecked()));
	}
