[Paraview] Tracing a particle's trajectory over time in paraview?

[John Biddiscombe]

Sorry, I forgot to mention that I do have somewhere a 
vtkParticleTrajectoryFilter that I had planned on getting working in 
sparticles (I just looked but can't find the code), I think I never 
quite finished it. I realize on second reading that you are interested 
in the trajectory rather than the particles themselves. If this is of 
interest, drop me a line and I'll try to find it and  get it working.
