---------------------------+------------------------------------------------
 The reason we have issues with MapGuideViewerApi.js is because it is
 trying to reinvent functionality that should be present in Fusion itself,
 namely APIs for digitizing geometry.

 The key to solving #569 is to have MapGuideViewerApi.js be a pure wrapper
 free of any global state (with the exception of Fusion and OpenLayers).
 This requires the map widget (that the MapGuideViewerApi.js functions are
 accessing) has the digitizing functionality built-in.
