// .NAME vtkPExtractGrid - Extract VOI and/or sub-sample a distributed
// structured dataset.
//
// .SECTION Description
// vtkPExtractGrid inherits from vtkExtractGrid and provides additional
// functionality when dealing with a distributed dataset. Specifically, when
// sub-sampling a dataset, a gap may be introduced between partitions. This
// filter handles such cases correctly by growing the grid to the right to
// close the gap.
