Minor suggestion: name the dictionaries something other than *Event,
because that seems like an event interface name.  EventInitializer or
EventParameters (and then CustomEventInitializer or
CustomEventParameters, etc.).

Also, I wonder if the event type should just be a plain argument outside
the dictionary.  I think every event you dispatch needs a type.

  var evt = document.createEvent("MouseEvent");
  evt.init("click", { clientX: 100, clientY: 150 });

looks OK to me.

Does it make sense to provide event interfaces with constructors?  A
pattern like:

  elt.dispatchEvent(new MouseEvent("click", { clientX: 100,
                                              clientY: 150 });

looks even better. :-)
