Description 

When using C# MapScript to create a mapObj using the mapObj constructor from a
map file, the extent of the object are not set properly after creation.

Tracking the instantiated mapObj through the MS Visual Studio 2003 debugger
reveals that the extent attributes minx, miny, maxx, maxy still have values of 0.0.

Development environment details:
- MS Visual Studio 2003 (VB.NET)
- DLLs (mapscript_csharp.dll, mapscript.dll, etc) from MS4W PHP4 Base
  Installer v1.5.4
- MS Windows XP Pro SP2 with IIS 5
- .NET Framework 1.1

The mapfile "Simple.map" is as follows.

        Dim p_map As mapObj = New mapObj(mapLocation & "Simple.map")
