super_union_span_span() Span * super_union_span_span ( const Span *  s1, const Span *  s2  ) Return the bounding union of two spans. Parameters [in] s1,s2 Spans Note The result of the function is always a span even if the spans do not overlap This function is similar to bbox_union_span_span with memory allocation
