Zooms to the full extent of the map window as defined in the map window properties.
This method is the equivalent of the Zoom > Unzoom menu command in the user interface.
This method always refreshes the map when the autoRefresh flag is set to True or when called from the onViewChanging or onMapLoaded events.
Note that this method does not work during a busy state. For additional information about the busy state, refer to "Handling Busy State and Map Refresh" in the Autodesk MapGuide Developer's Guide.
