Description

Because this code is called with 14.18 fixed point values during antialiasing, using "valuea - valueb" as a comparison causes integer overflows for moderate values of valuea and valueb of opposite sign (eg., valuea = 8000.0f, valueb = -8000.0f). See http://crbug.com/18896, layout test LayoutTests/svg/carto.net/window.svg.
