    Don't ungrab pointer on leave-notify events
    
    If we ungrab the pointer on leave-notify events, this breaks
    the automatic grabs when a button is pressed in absolute pointer.
    A symptom of this is that if you press to start highlighting text
    in a gedit window in a server, and move the mouse outside the VNC
    widget and release the button, the server will never see the mouse
    up event. We must preserve grabs upon button press so that the
    VNC server always sees the eventual release events.
