    /*/*from  w  w w .ja  v  a  2s .com*/
     * Avoid processing the same event twice (issue with the GWT dispatcher). 
     * If you sink events on a child, but do not set a listener (as in the case of UIObjects), 
     * the following will happen:
     *
     * 1) child element's onXXX event handler is invoked
     * 2) $wnd.__dispatchEvent() is called with the event and child element
     * 3) this crawls up the heirarchy until it finds a GWT event listener (i.e. CComposite)
     * 4) CComposite.onBrowserEvent() is called (e.target = child, e.currentTarget = child)
     * 5) the event bubbles up to the parent element
     * 6) parent element's onXXX event handler is invoked
     * 7) $wnd.__dispatchEvent() is called with the event and the parent element
     * 8) CComposite.onBrowserEvent() is called (e.target = child, e.currentTarget = parent)
     * 
     * @see DOMImplStandard#init()
     * @see Tree#onBrowserEvent(Event)
     * 
     * Note: don't test current target when capturing. DOM.eventGetCurrentTarget() returns $wnd 
     * when capturing in Firefox and $wnd.equals() blows up. 
     * @see http://groups.google.com/group/Google-Web-Toolkit-Contributors/browse_thread/thread/41f12a9def68f97a
     * 
     * Note: eventGetCurrentTarget(event) is wrong in FocusImplOld (Safari, old Mozilla, Opera)--it returns the 
     * nested INPUT. Focus events don't bubble anyway, so bypass the check in this case. Bleh.
