Selection of graphics output (GO) options for PK_TOPOL_render_facet_o_t


Specific Errors:

  This selects which additional data are output through GO

    - surface normals
    - surface parameters
    - model edge entities

  and how these are output.

  Facets may be output in one of two ways: all facets for a particular body are
  output before facets belonging to any other body are output, or, the facets
  of faces of the bodies being facetted can be interleaved.  See documentation
  of PK_topol_facet_go_interleaved_t for details.
