[vtkusers] vtkStructuredPointsWriter writes a blank file

[Bill Lorensen]

The data extents you specified will produce a zero length structured points.

For the tiff reader, you need not specify the extents if you want all
of the data. And I'm not sure what the other methods will do in the
tiff reader.
vtkTIFFReader *TIFFReader = vtkTIFFReader::New();
    TIFFReader -> SetFilePrefix("/Users/matheusviana/Desktop/images/im");
    TIFFReader -> SetFilePattern("%s%04d.tif");
    TIFFReader -> Update();
