r183494 added support for the font-synthesis property for the iOS and Mac ports, but we need this for Freetype ports as well.

Why the difference in order between weight and italic?

No reason. I think I just did that for some intuitive sense of readability. I'm happy to make it consistent. :)

Nit: extra space here

We're doing an extra check for < FontWeightBold here but I guess it's so simple that we can leave with it.

I think in this case we have to check whether the font needs the synthetic bold and also whether the font-synthesis property allows it.
