I don't think it's a great idea to make another of these. If you can't use the
SkFontMgr, I would instead save off the created factory below and have a getter
for that.

That makes sense. Any idea where this code should live then? Probably not in
public/renderer...

[scottmg, 2014/06/26 21:05:17]

Yeah, I think I wouldn't bother sharing with this code now.

There's factory creation in Skia, since it's happening in browser, we don't do
any of that there yet (UI is still GDI rendered).

I _think_ (though am not certain) that code in skia/ext can use
third_party/skia/src/utils/win/SkDWrite.cpp, so sk_get_dwrite_factory() there
might be the easiest, if you just have the content/common code call a utility
function there.
