    PK_proj_face_hidden_no_c     Each face is projected without regard to
                                 whether other faces obscure it.

    PK_proj_face_hidden_array_c  Each face is projected with regard only to
                                 whether other faces in the input array
                                 obscure it.

    PK_proj_face_hidden_body_c   Each face is projected with regard to
                                 whether all faces in the parent body
                                 obscure it, even if these are not supplied
