/**
* @class vtkCookieCutter
* @brief cut vtkPolyData defined on the 2D plane with one or more polygons
*
* This filter crops an input vtkPolyData consisting of cells (i.e., points,
* lines, polygons, and triangle strips) with loops specified by a second
* input containing polygons. Note that this filter can handle concave
* polygons and/or loops. It may produce multiple output polygons for each
* polygon/loop interaction. Similarly, it may produce multiple line segments
* and so on.
*
* @warning
* The z-values of the input vtkPolyData and the points defining the loops are
* assumed to lie at z=constant. In other words, this filter assumes that the data lies
* in a plane orthogonal to the z axis.
*
