    screenShield: Only wake up screen when active
    
    We treat wake up requests the same as user activity, as in general
    the two behave the same: Turn on the screen and reset the idle watch
    until the system becomes idle again.
    
    The big exception is when the screen isn't locked yet. In that case
    user activity should interrupt the automatic screen lock, but a
    request to wake-up the screen (like showing a notification) should
    not.
    
    Address this by ignoring wake-up requests while the screen shield
    isn't active, as we can expect the screen to still be turned on at
    that point.
