        //      Returns: none
        //
        //      Purpose: Called BEFORE the title screen is added to the widget manager
        //      by GameApp. This initializes some things like the images used for
        //      our hyperlink widget.

        //      Returns: none

        //      Purpose: This function is automatically called by the widget manager
        //      which also passes a pointer to itself, when the TitleScreen class is
        //      added to its list of widgets. Every widget gets this function
        //      called when it is first added. It useful to use this function to

        //      removed from its list of widgets. Every widget gets this function

        //
        //      Purpose: This method is called by the WidgetManager when a button widget
        //      is first pressed and THEN released. You can use ButtonPress if you want
        //      to know when the button is first pressed (before it is released).
        //      theId is the integer ID that was assigned to the button when it was

        //      Returns: none

        //      resources, to let the title screen know that it should unhide and
        //      enable the continue link, so the user can start playing the game.
