Discussion

This method checks the element to determine if it contains scrolling data suitable for dispatching in an event. If it does, the method stores a reference to the element for later use. When the driver object receives subsequent reports from the device, it uses the information in the stored scrolling elements to dispatch scrolling-specific events.
