* BREAKING CHANGE: All EventSource and MouseTracker event handler method signatures changed to 'handlerMethod(event)' where event == { eventSource, userData, ... } (#251) (Also fixes #23, #224, #239)
* The new eventSource property in the event object replaces the old eventSource parameter that was passed to handler methods.
* Where the event object duplicated the eventSource value, those properties have been removed. This effects the following events:
