829     * If a flag is not set, fire "up" events for all keys which correspond to
830     * the flag. Note that "down" events are not fired here because the flags
831     * checked here do not tell what exact keys are down.
832     *
833     * If one of the keys corresponding to a flag is down, we rely on
834     * -[NSEvent keyCode] of an event whose -[NSEvent type] is
835     * NSEventTypeFlagsChanged to know the exact key which is down, which has
836     * the following two downsides:
837     * - It does not work when the application is inactive as described above.
838     * - It malfactions *after* the modifier state is changed while the
839     *   application is inactive. It is because -[NSEvent keyCode] does not tell
840     *   if the key is up or down, and requires to infer the current state from
841     *   the previous state. It is still possible to fix such a malfanction by
842     *   completely leaving your hands from the keyboard, which hopefully makes
843     *   this implementation usable enough.
