Floating point values are printed with leading zeros on Windows, while on the Mac there is no leading value. E.g., the value "1.23e-15" on the Mac platform will be printed as "1.23e-015" under Windows. This causes a number of SVG tests under Windows (and therefore, WinCairo) to fail to match the equivalent result on the Mac. For example, "svg/css/composite-shadow-example.html" will show this behavior. As documented on MSDN (http://msdn.microsoft.com/en-us/library/0fatw238(v=vs.80).aspx), we can force the Windows test harness to output using the proper format using: _set_output_format(_TWO_DIGIT_EXPONENT); Using this change will allow us to have more sharing between the Win/WinCairo and Mac results. It looks like there are a number of Windows results that were rebaselined just because of this small formatting problem.
