767     * If CapsLock state is changed, "up" and "down" events will be fired in
768     * sequence, effectively updates CapsLock state on the guest.

770     * The other flags
771     * ---------------
772     *
773     * If a flag is not set, fire "up" events for all keys which correspond to
774     * the flag. Note that "down" events are not fired here because the flags
775     * checked here do not tell what exact keys are down.
776     *
777     * If one of the keys corresponding to a flag is down, we rely on
778     * -[NSEvent keyCode] of an event whose -[NSEvent type] is
779     * NSEventTypeFlagsChanged to know the exact key which is down, which has
780     * the following two downsides:
781     * - It does not work when the application is inactive as described above.
782     * - It malfactions *after* the modifier state is changed while the
783     *   application is inactive. It is because -[NSEvent keyCode] does not tell
784     *   if the key is up or down, and requires to infer the current state from
785     *   the previous state. It is still possible to fix such a malfanction by
786     *   completely leaving your hands from the keyboard, which hopefully makes
787     *   this implementation usable enough.
