PK_mixed_intersection_t

typedef int PK_mixed_intersection_t;

Used in:

PK_FACE_intersect_face_o_t
PK_FACE_intersect_surf_o_t
PK_SURF_intersect_surf_o_t

This datatype specifies whether to return curves of type polyline, classic,
or both in mixed face-face, face-surface, and surface-surface intersections.

PK_mixed_intersection_t can take the values:
    PK_mixed_intersection_pline_c           return polyline intersection curve
    PK_mixed_intersection_classic_c         return classic intersection curve
    PK_mixed_intersection_both_c            return both
