EventImpl is an implementation of the basic "generic" DOM Level 2 Event object. It may be subclassed by more specialized event sets. Note that in our implementation, events are re-dispatchable (dispatch clears the stopPropagation and preventDefault flags before it starts); I believe that is the DOM's intent but I don't see an explicit statement to this effect.

The DOM doesn't deal with constructors, so instead we have an initializer call to set most of the read-only fields. The others are set, and reset, by the event subsystem during dispatch.

Note that init() -- and the subclass-specific initWhatever() calls -- may be reinvoked. At least one initialization is required; repeated initializations overwrite the event with new values of their parameters.
