        This sample shows how to overlay KML Ground Overlay information as an image layer on the map.
        KML ground overlays provide north, south, east, and west coordinates and a counter-clockwise rotation,
        where as the image layer expects coordinates for each corner of the image. The KML ground overlay in this sample is of the Chartres cathedral and sourced from <a href="https://commons.wikimedia.org/wiki/File:Chartres.svg/overlay.kml">wikimedia</a>.
