Since now a new WLine is not created if its start point lies in another earlier computed WLine. It allows avoiding creation of duplicate WLines in the intersection result. <!break> 1. Methods IsOutSurf1Box(...), IsOutSurf2Box(...), IsOutBox(...) for classes IntSurf_LineOn2S and IntPatch_RLine have been created.
