[Paraview] changing the current view in pvw

[Sebastien Jourdain]

Normally loading a state file should re-initialize everything, so the

activeView = paraview.CreateIfNeededRenderView();
paraview.ResetCamera();
activeView.setCenterOfRotation(activeView.getCameraFocalPoint());

should be redone and all the renderer should be re-init with the new view id.
