[Paraview] can not drag object in TestPVSynchronizedRenderWindows

[Utkarsh Ayachit]

Call the following after the view is created.

void setupCameraManipulators(vtkSMProxy* view)
{
  vtkSMProxyManager* pxm = vtkSMProxyManager::GetProxyManager();
  vtkIdType cid = view->GetConnectionID();
  vtkSMProxy* manip = pxm->NewProxy("cameramanipulators",
    "TrackballRotate");
  vtkSMPropertyHelper(manip, "Button").Set(1);
  vtkSMPropertyHelper(manip, "ManipulatorName").Set("Rotate");
  manip->UpdateVTKObjects();
  vtkSMPropertyHelper(view, "CameraManipulators").Add(manip);
  manip->Delete();

  manip = pxm->NewProxy("cameramanipulators",
    "TrackballZoom");
  vtkSMPropertyHelper(manip, "Button").Set(3);
  vtkSMPropertyHelper(manip, "ManipulatorName").Set("Zoom");
  manip->UpdateVTKObjects();
  vtkSMPropertyHelper(view, "CameraManipulators").Add(manip);
  manip->Delete();

  manip = pxm->NewProxy("cameramanipulators",
    "TrackballPan1");
  vtkSMPropertyHelper(manip, "Button").Set(2);
  vtkSMPropertyHelper(manip, "ManipulatorName").Set("Pan");
  manip->UpdateVTKObjects();
  vtkSMPropertyHelper(view, "CameraManipulators").Add(manip);
  manip->Delete();
}
