[Paraview] poor man's particle tracer

[Berk Geveci]

What about streamline -> python programmable filter -> glyph? The
programmable filter has to behave as a time source. It can do that by
setting, err, I think, TIME_VALUES() and TIME_RANGE() keys in
RequestInformation() and responding to , err, UPDATE_TIME_VALUES() in
RequestData(). It could extract the nth point in one or more
streamlines where n is the time step. You can then animate it using
the standard animation support (I hope).
