This function finds self-intersections in the given curve.


Specific Errors:
    PK_ERROR_invalid_geometry        The curve has invalidities other than
                                     self-intersections (PK_ERROR_mild)
    PK_ERROR_find_self_int_failed    Failure (PK_ERROR_serious)


This function finds regions of self-intersection on a curve, and returns
information about the regions found, if any.

Each self-intersection on the curve occupies a physical region in three-space,
and is made up of two or more parametric regions which intersect each other.
Note that self-intersections on a curve will always be of 'type'
PK_self_int_type_general_c.
