			// Because the target of the touch event that triggered the vclick
			// can be different from the target of the click event synthesized

			// some browsers will fire mouse/click events for a link that is near
			// a touch event, even though the target of the touchstart/touchend event
			// says the user touched outside the link. Also, it seems that with most
			// browsers, the target of the mouse/click event is not calculated until the
			// time it is dispatched, so if you replace an element that you touched
			// with another element, the target of the mouse/click will be the new
			// element underneath that point.
			//
			// Aside from proximity, we also check to see if the target and any
			// of its ancestors were the ones that blocked a click. This is necessary
			// because of the strange mouse/click target calculation done in the
			// Android 2.1 browser, where if you click on an element, and there is a
