Some internal fonts for OS X are not listed in availableFontFamilies, which means that WebCore fails to find them. In these cases we should look for the fontName, rather than the familyName. <rdar://problem/13474743>

Comment on attachment 195279 [details] Patch Looks good
Not sure what is up with the windows tests: svg/dom/SVGScriptElement/script-change-externalResourcesRequired-while-loading.svg -> failed
Since the files changed here aren't even compiled on Windows, it seems like a misleading result. I'll keep an eye on the test bots.
