/**
* @class vtkRecoverGeometryWireframe
* @brief Get corrected wireframe from tessellated facets
*
* This filter create an edge mask that is used at render time to ignore the
* rendering of specific edges in wireframe mode. For that it checks a cell attribute
* so that each adjacent cells having the same attribute value will not display an
* edge between them.
*
* The main usage of this filter is at the output of vtkDataSetSurfaceFilter or
* vtkGeometryFilter, when we are subdividing non-linear cells but we still want to
* visualize the edges of the original cells. In this case the cell attribute
* will usually be the original cell id values.
*
* @warning As the edge flag mechanism does not allow to specify a single edge
* from a point the filter might duplicate some points, so topology
* is not preserved.
