currently we turn off text antialiasing by default for Chromium DRT on Windows, but not on the Mac (or Linux, I don't think). I believe this is probably a major source of version-specific pixel-test differences, as lots of tests render differently on different versions of Mac OS because text is antialiases slightly differently by default.

I can see little benefit to using the default text aliasing for tests that don't care about how the text is drawn, and that's most of them. As long as we can enable it for tests that do actually care, it seems reasonable to default to it being off. 

Anyone object?
