/**
 * @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 trim loops specified by a second
 * input containing polygons and/or polylines. The input vtkPolyData and the
 * loops must lie on the same plane. 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. (The input to cookie cut (input0) is referred to as the input
 * mesh, while the loops used to cut the input mesh (input1) are referred to
 * as the trim loops.)
 *
 * The filter has the option to pass through and generate point and cell
 * data.  If PassCellData is enabled, then the cell data associated with the
 * cropped cells, or cells passed through from the input mesh, are passed
 * through to the output. If PassPointData is enabled, then in similar
 * fashion the point data is passed through; however new points generated by
 * intersection may have point data interpolated in one of two ways. First,
 * the input mesh edges are interpolated at the new intersection points to
 * generate point data, or the trim loop edges are interpolated at the new
 * intersection points to generate point data. Note: for PassPointData and
 * point interpolation to function, the filter requires that the point data
 * attributes (from the mesh and trim loop) are exactly the same. If they are
 * not, then a set intersection operation is performed which uses the point
 * data arrays common to both the mesh and trim loops.
 *
 * @warning
 * The mesh and trim loops must lie on the same plane and the plane may be
 * arbitrarily oriented. If not on the same plane, tolerancing issues can
 * produce erratic results.
