When using the Carbon API, what is the last event a window can
receive, and how do I ensure (what type spec do I need) that I receive
it? Also, do I need to CFRelease the EventHandlerRef I got from
InstallEventHandler, or can I just ignore it?

Will calling RemoveEventHandler in response to an event ensure that I
don't receive future events for the given target? Same question about
the EventHandlerRef again.

You was to use kEventClassHIObject, kEventHIObjectDestruct.

Do _not_ CFRelease the handler ref.

Yes, same answer about the handler ref.
