/**
* 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.
