[vtkusers] Get vtkPolyData from vtkMapper in vtkActor using Java API

[Bill Lorensen]

Here is what I do in C++:
vtkSmartPointer<vtkActorCollection> actors =
    vtkSmartPointer<vtkActorCollection>::New();
  actors = renderer->GetActors();
  actors->InitTraversal();
  for (vtkIdType a = 0; a < actors->GetNumberOfItems(); ++a)
    {
    vtkActor * actor = actors->GetNextActor();
    vtkPolyData *pd = vtkPolyData::SafeDownCast(actor->GetMapper()->GetInput());
    vtkSmartPointer<vtkCleanPolyData> clean =
      vtkSmartPointer<vtkCleanPolyData>::New();
    clean->SetInputData(pd);
    vtkSmartPointer<vtkPolyDataNormals> normals =
      vtkSmartPointer<vtkPolyDataNormals>::New();
    normals->SetInputConnection(clean->GetOutputPort());
    normals->Update();
    vtkPolyDataMapper *mapper =
vtkPolyDataMapper::SafeDownCast(actor->GetMapper());
    mapper->SetInputData(normals->GetOutput());
    }
