* @class vtkPExtractGrid
* @brief Extract VOI and/or sub-sample a distributed
* structured dataset.
*
*
* 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.
