* @class vtkPStreamTracer

* This class implements parallel streamline generators. By default all
* processes must have access to the WHOLE seed source, i.e. the source must
* be identical on all processes. If property `UseLocalSeedSource` is set to
* false then this filter will aggregate seed sources from all ranks into a
* single dataset.
