This field can take any one of the following values.
    PK_render_param_no_c        : no parametric hatching (default)
    PK_render_param_attrib_c    : parametric hatch faces which have
                                  parametric hatch attribute
    PK_render_param_spaced_c    : parametric hatch using the u/v spacing
                                  in 'param_u' and 'param_v' and
                                  the start parameters given by
                                  'param_u_start' and 'param_v_start'
                                  in PK_TOPOL_render_line_o_t.
                                  Behaves as PK_render_param_spaced_free_c
                                  when used in PK_GEOM_render_o_t, or if
                                  'param_u_start' and 'param_v_start' are not
                                  set.
    PK_render_param_spaced_free_c
                                : parametric hatch using u/v spacing in
                                  'param_u' and 'param_v' in
                                  PK_TOPOL_render_line_o_t or
                                  PK_GEOM_render_o_t without a fixed
                                  start parameter.
    PK_render_param_number_free_c
                                : parametric hatch with the number of
                                  u/v hatch lines given by 'param_u_number'
                                  and 'param_v_number' in
                                  PK_TOPOL_render_line_o_t or
                                  PK_GEOM_render_o_t without a fixed
                                  start parameter.
