One thing we could do is simply save copies of rendered text under a 
variety of configurations and compare them from one release to the next. 
Actually, FreeType is just now starting to do that itself [1].

I started to keep track on the Web page below, at least in relation to 
this particular code change, but I haven't expanded it to other font 
types or platforms yet (Windows and macOS).
