    /// The Navigation interface is used for creating and injecting navigation
    /// related events such as mouse button presses, cursor motion and key presses.
    /// The associated library also provides methods for parsing received events, and
    /// for sending and receiving navigation related bus events. One main usecase is
    /// DVD menu navigation.
    ///
    /// The main parts of the API are:
    ///
    /// * The GstNavigation interface, implemented by elements which provide an
    ///  application with the ability to create and inject navigation events into
    ///  the pipeline.
    /// * GstNavigation event handling API. GstNavigation events are created in
    ///  response to calls on a GstNavigation interface implementation, and sent in
    ///  the pipeline. Upstream elements can use the navigation event API functions
    ///  to parse the contents of received messages.
    ///
    /// * GstNavigation message handling API. GstNavigation messages may be sent on
    ///  the message bus to inform applications of navigation related changes in the
    ///  pipeline, such as the mouse moving over a clickable region, or the set of
    ///  available angles changing.
    ///
    /// The GstNavigation message functions provide functions for creating and
    /// parsing custom bus messages for signaling GstNavigation changes.
