SquareConfusion function was created in FoundationClasses module -> TKMath toolkit -> Precision package.
The function returns square of Precision::Confusion().
SquareConfusion function was corrected in FoundationClasses module -> TKMath toolkit -> Precision package.
Squares of Precision::Confusion() were replaced by Precision::SquareConfusion().
The two corrected if-clause conditions were always true.
In FixSmallAreaWire where the documentation says: "Detects wires with small area (that is less than 100*Precision::PConfusion(). Removes these wires if they are internal." and the bugfix conforms to this.
For 'NeedCheckSplitWire' option in the Perform method the same assumption is made although no documentation on this could be found.
Added check for consistency properties of closure and existence of free boundaries in shell (modified ShapeFix_Shell::Perform()
Added new message in SHMessage/SHAPE.us)
