This structure is part of the PK_FACE_replace_surfs_o_t options
structure. It contains the vertex position replacement data.

Description of fields:



'n_vertices'        Number of vertices to modify. Length of the
                    'vertices', 'positions' and 'tolerances' arrays.
                    The default value is 0.


'vertices'          Array of the vertices to modify.
                    The array default value is NULL.


'positions'         Array of the user-provided replacement positions for
                    the vertices. The array default value is NULL.


'tolerances'        Array of tolerances associated with the corresponding
                    vertices in 'vertices'.  A value of 0.0 indicates that the
                    associated vertices are to be treated as accurate.
                    The array default value is NULL.

                    The corresponding vertices in the resulting body will not
                    necessarily have this tolerance; if possible the vertex
                    will be made accurate.

                    Note: The tolerance will be ignored for facet vertices.

                    Note: Vertices which will be mixed after the operation must
                          have a tolerance of at least 5 times the session
                          precision.
