[vtkusers] vtkPointPicker sample/question/problem

[Will Schroeder]

Try observing EndPickEvent. If I remember correctly 
vtkRenderWindowInteractor does not invoke "PickEvent" on itself.

Instead of

>   // init callback
>   vtkMyCallback *callback = vtkMyCallback::New();
>   iren->AddObserver(vtkCommand::PickEvent, callback);

try

>   // init callback
>   vtkMyCallback *callback = vtkMyCallback::New();
>   iren->AddObserver(vtkCommand::EndPickEvent, callback);
