[Paraview] ParticleTracer filter

[Andy Bauer]

I think you're missing a seed for the particle flow paths. You can use
something under the sources menu to create that to seed the initial points
for the particle tracker filter. When the Change Input Dialog window comes
up after you're created the particle paths filter, click on Seed Source and
then choose an input for your seeds.
