[vtkusers] Update() methods on multithreaded applications

[David Gobbi]

Hi Enzo,

If you have an ITK pipeline or a VTK pipeline that only doesn't do any
display (i.e. that only does IO or processing), then put it into a QThread
so that it can update asynchronously.  When the thread re-joins your
application, you get the pipeline's output and connect it to your display
pipeline.
