This flag is for resoving the sync/async issue.

It'd be good to come up with a neater way to express this. What this really
means is, "when true, the event is the result of an IME translation". Can this
occur with any type of key event (e.g. both KeyDown and KeyUp)? Seems like you
could make an argument that this is a new event type. Windows treats it as such
(WM_IME_CHAR).

Thanks for the suggestion. I've added a new event type called
TranslatedKeyEvent.
