Summary0013267: Summary: FIxShape works incvorrectly on small contours
DescriptionFixShape shape healing operation sometimes produces invalid result on some
platforms (Win32, Mandriva 64-bit).

Analysis has shown that in some cases - when small contours are present in a
shape - contour area is calculated wrongly. Unfortunately, it is very difficult
to prepare a BREP file with a suitable example, since export to BREP and
subsequent import lead to slightly different geometry (due to round-up errors).
The problem is likely to be located at line
if(area2d<Precision::PConfusion()*Precision::PConfusion()) return
Standard_False; (str 807)
in file ShapeFix_IntersectionTool.cxx

and documentation updates		Documentation remark, added by GKA 2006-09-28 15:18:40:

Improvements:
Fixing bug in the ShapeFix_IntersectingTool for cases self-intersectig countour
if areas of parts of countour are approximately equal to each other.
