Subclass of vtkParticleTracerBase and vtkStreamTrancer make input timestep to last.
I rendered a .pvd file with 155 timesteps . And then do a vtkStreackLineFilter on it. The timesteps of pvd file changed to last. I test the other subclass of vtkPaticleTrancerBase and vtkStreamTrancer,and got the same result. I think that the filters should not change its input.output.ziptestParticleTrancer.cpp
