Summary0031005: Modeling Algorithms - Offset wire algorithm is unstable
DescriptionThe algorithm for offsetting wires (BRepFill_OffsetWire) is unstable - little shift of the wire leads to a fail.

The problem has been discovered while working on the issue #0030878 in the test case offset/wire_closed_outside_0_005/D1.
Steps To Reproducebrestore [locate_data_file offset_wire_041.brep] s
mkoffset result s 1 17.06405
# OK
ttranslate s 0.1 0.1 0
mkoffset sresult s 1 17.06405
