isPress, isRelease :: (a, KeyButtonState) -> Maybe a

registerTaskCallbacks :: (MonadIO m, MonadTask Event m) => IO (m ())

registerTaskCallbacks sets up all event callbacks, and returns a waitEvent equivalent function for task monad, which must be called repeatedly in order to pump events to other task co-routines.

These task co-routines should use watch to select event of interest, and they should be forked prior to the waitEvent call.
