// .NAME vtkPVStreamingView - a view that renders in a streaming fashion.
// .SECTION Description
// vtkPVStreamingView uses a vtkStreamingDriver to cycle all of the
// vtkPVStreamingRepresentations shown within it through their pieces.
// Since the data is rendered one piece at a time, the entire data set
// is never resident in RAM at once.
// Switching the Driver will make it render in iterative, prioritized and
// multiresolution progressions.
