Summary CSS3 calc: cannot determine sign of calculated Length without a maxValue

WebCore/platform/Length.h defines the following functions: bool isZero() const bool isPositive() const bool isNegative() const A calculated value in a Length is always a mixed percent/absolute, eg -webkit-calc(100% - 10px). Without a maxValue (ie the value that equates to 100%) passed in to these functions, we cannot determine the sign or the zero-ness of the result.
