Methods D0, D1, D2, D3, DN of the class GeomEvaluator_OffsetSurface are extended by additional tweak to compensate failure of normal calculation in degenerated points on triangular surfaces. If the point where normal has failed to calculate is located on parametric boundary of the base surface, one more attempt is made with the point shifted towards interior by Precision::PConfusion().
