It's time to stop using SafariTheme.dll during DumpRenderTree testing. We don't ship software using SafariTheme.dll anymore, so it's silly to use its output as the basis for our rendering health. Furthermore, with the release of Yosemite, the drawing style used in SafariTheme no longer matches our Mac baselines. Consequently, many tests will begin failing anyway. Let's seize this opportunity to rebaseline Windows against its native drawing style.
