332 Final stage of contour processing.
334 1. Contour, which was retrieved using border following, is added to
335 the contour tree. It is the case when the icvSubstituteContour function
336 was not called after retrieving the contour.
338 2. New contour, assigned by icvSubstituteContour function, is added to the
339 tree. The retrieved contour itself is removed from the storage.
343 the contour is removed completely.
344 2b. In hierarchical case, the header of the contour is not removed.
345 It's marked as "link to contour" and h_next pointer of it is set to
346 new, substituting contour.
350 retrieved contour completely if plane case and
355 restriced set of methods). Some characteristics of contour can be computed in the
