[Marc-André Lureau]

----- Original Message -----
> Connect to the GdkKeymap::state-changed signal to detect when the client
> keyboard modifiers have changed. This keeps the client and the guest in sync
> even when the SpiceDisplay widget isn't focused. New values are only sent
> down
> to the guest if the new value is different than the current value.
