Processing of bergstrichs

It is executed after processing of isolines. The objects are processed the types of which are contained in the Bergstrichs dialog page. If bergstrich does not belong to any of the remaining isolines, then it is deleted. Belonging of bergstrich to the isoline is determined by the proximity of the first point of the bergstrich metric and the current point of the isoline metric. In this case, the processing tolerance the Maximum distance from isoline to bergstrich is used. When processing, the minimum distance between the bergstrich and all remaining isolines is determined. If the found minimum distance is greater than the tolerance, that is, the Bergstrich is far from all isolines, then it is removed.
