An extended draw-command trotate (ttranslate, tmirror, ...) by an additional parameter "-copy". New check of edge range is added in BRepCheck/BRepCheck_Edge.cxx The same checking is added in ShapeAnalysis_Edge.cxx Fixing this problem is added in ShapeFix_Wire.cxx GeomLib::SameRange(...) and BRepTools_TrsfModification::NewCurve2d(...) are modified to avoid exception in TrimmedCurve
