[Paraview] Moving clip plane

[Utkarsh Ayachit]

State file attached. It uses can.ex2.

The crux is in the Python Animation Cue script:

def start_cue(self): pass

def tick(self):
  ts = self.GetClockTime()
  from paraview import simple as pvs
  clip = pvs.FindSource("Clip1")
  ip = clip.Input
  ip.UpdatePipeline(ts)
  bds = ip.GetDataInformation().GetBounds()
  center = [ (bds[0] + bds[1]) / 2.0,
             (bds[2] + bds[3]) / 2.0,
             (bds[4] + bds[5]) / 2.0 ]
  clip.ClipType.Origin = center

def end_cue(self): pass
