Contains optional controls on isocline curve generation.

Used in:

PK_SURF_make_cus_isocline

Description of fields:

'isocline_split'         If this option is set to PK_isocline_split_no_c, the
                         default value, isocline curves will not be split.
                         If setting it to PK_isocline_split_convexity_c,
                         isocline curves will be split at the points where
                         the draw convexity changes.

'mesh_normal_field'      If this option is set to
                         PK_MESH_normal_field_mvertex_c, mesh vertex normals
                         will be used to generate isocline curves.
                         If set to PK_MESH_normal_field_mfacet_c, facet
                         normals will be used. This option is ignored on
                         classic geometry.
