-/**
- * 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.
