    Reviewed by Tim Horton.

    In cases where the result is computed by CalcExpressionOperation.cpp, the result ends up being squared, because we're missing a sqrt() operation.
    The result is correct for cases computed by CSSCalcOperationNode.cpp however, ideally code should be shared to prevent these types of bugs.
