    session: Implement NotifyPointerAxis()
    
    Now that the remote desktop API in gnome-remote-desktop has been
    synchronized with API in mutter, implement the NotifyPointerAxis
    function.
    This function allows a remote desktop client to scroll without using
    discrete steps, which is necessary for RDP clients, where the user
    uses a high resolution mouse wheel.
