Is there a reason you need to explicitly call through to the InputMethod here
and not the dispatcher as before? Shouldn't the later still work?

[Shu Chen, 2015/06/04 15:59:25]

The dispatcher->OnEventFromSource() now doesn't work because it happens after
IME.
The EventSource::SendEventToProcessor() happens before IME but it is protected.
Should make it as public?

No, keep it as you have it.
