Like some others, I also object to keeping the "legacy" filter as the default.
Freetype doesn't call it legacy without reason: it is optimized for one special
rendering preference, full native hinting (IMO it's doing badly even in that
case), and is crap in all others. Moreover, if the fonts do not have
high-quality hinting instructions, it does a bad job as well. I think this
isn't even subjective, the color fringing of the "legacy" filter is bad
regardless of display and/or personal preferences.

If you still think it matters to not "surprise" users (I certainly would call
improved text rendering a good surprise, though), the FIR3 filter might be a
good choice for the default, but I'd surely go for the default (FIR5) by
default. This is how it should be anyway.
