 Using Maestro API 4.0.4 and MGOS2.2 I have a problem when creating a
 runtime map. The display scales are not set correctly.

 I have a land parcel layer in the map where the scale range has been set
 to 0:5000

 The source code is:
       IMapDefinition mdef =
 (IMapDefinition)con.ResourceService.GetResource("library://maps/testmap.mapdefinition");
       IMappingService mSvc =
 (IMappingService)con.GetService((int)ServiceType.Mapping);
       RuntimeMap map = mSvc.CreateMap(mdef);
       map.Save();

 If I then check the layer display scales they are not correct:
 map.Layers["landparcels"].ScaleRanges[0].MinScale is 0.0
 map.Layers["landparcels"].ScaleRanges[0].MaxScale is
 1.7976931348623157E+308

 In other words, it is infinite instead of 5000.
 If I check the IMapDefinition i cannot see that the layers in the basemap
 contain any information about layer scale ranges, so perhaps the problem
 is that the mapdefinition does not contain the scale ranges to be
 duplicated when creating the runtime map.
 I did not check if Maestro 5 has the same issue, but if so please fix both
 v4 and v5.

 I made a workaround by getting the ILayerDefinition from the layers
 LayerDefinitionID (using ResourceService.GetResource()). Then I can cast
 it to a IVectorLayerDefinition and read the VectorScaleRange property.
