There seem to be many places in VTK tests where vtkImageReader2 is
used to read the headsq/quarter dataset. It seems to be .nhdr format.
Is there not a better way to read this data set?

Can code like this:

  vtkSmartPointer<vtkImageReader2> reader =
    vtkSmartPointer<vtkImageReader2>::New();
  reader->SetFilePrefix(argv[1]);
  reader->SetDataExtent(0, 63, 0, 63, 1, 93);
  reader->SetDataSpacing(3.2, 3.2, 1.5);
  reader->SetDataOrigin(0.0, 0.0, 0.0);
  reader->SetDataScalarTypeToUnsignedShort();
  reader->SetDataByteOrderToLittleEndian();
  reader->UpdateWholeExtent();

be extracted from a header instead by one of the subclasses?
