 The "global" variables defined in MapGuideViewerApi.js are not truly
 unique. You can see this when you try to use the Redline widget, which
 calls into the digitizing functions provided by this module.

 Every time the widget digitizes a geometry, the MapGuideViewerApi module
 will repeatedly add new OpenLayers.Layer.Vector and
 OpenLayers.Control.DrawFeature objects to the map despite there being a
 "global" boolean guard that is supposed to protect against this.
