/**
 * Events: (copy/paste from apple.com)
 *
 *  webkitmouseforcewillbegin: This event occurs immediately before the mousedown event. It allows you to
 *   prevent the default system behavior, such as displaying a dictionary window when force clicking on a
 *   word, in order to perform a custom action instead. To prevent the default system behavior, call the
 *   preventDefault() method on the event.
 *  webkitmouseforcedown: This event occurs after the mousedown event, once enough force has been applied
 *   to register as a force click. The user receives haptic feedback representing the force click when this
 *   event occurs.
 *  webkitmouseforceup: This event occurs after a webkitmouseforcedown event, once enough force has been
 *   released to exit the force click operation. The user receives haptic feedback representing the exit
 *   from force click when this event occurs.
 *  webkitmouseforcechanged: This event occurs whenever a change in trackpad force is detected between the
 *   mousedown and mouseup events.
