Represents an input event fired on a pc.ElementComponent. When an event is raised
on an ElementComponent it bubbles up to its parent ElementComponents unless we call stopPropagation().
|element||The ElementComponent that this event was originally raised on.
|event||The MouseEvent or TouchEvent that was originally raised.
ElementInputEvent(event, element, camera)
Create an instance of a pc.ElementInputEvent.
Stop propagation of the event to parent pc.ElementComponents. This also stops propagation of the event to other event listeners of the original DOM Event.
