/**
* @class vtkRectilinearGridClip
* @brief Reduces the image extent of the input.
*
* vtkRectilinearGridClip will make an image smaller. The output must have
* an image extent which is the subset of the input. The filter has two
* modes of operation:
* 1: By default, the data is not copied in this filter.
* Only the whole extent is modified.
* 2: If ClipDataOn is set, then you will get no more that the clipped
* extent.
