0026419: [Regression?] Export of a reversed face leads to crash in 6.9.0 although proceeded in 6.8.0

Browse Source 
Take basis surface from trimmed surfaces during IGES writing, because pcurves will be transformed, so trim will be shifted, accorded to new face bounds,
fix updating of seam edge,
change condition of using Segment during exporting periodic BSpline surfaces to IGES (if bounds are not in one period).
