// .NAME vtkDistributedStreamTracer - Distributed streamline generator
// .SECTION Description
// This filter integrates streamlines on a distributed dataset. It is
// essentially a serial algorithm: only one process is active at one
// time and it is not more efficient than a single process integration.
// It is useful when the data is too large to be on one process and
// has to be kept distributed.
