.... it certainly makes sense in some contexts. My print bible says to
keep fixed leading unless this is overridden somehow. The problem with a
splitting algorithm is that it's not possible in general to say where to
put the leading change. I guess what you have to do is some kind of meta
change that says 'allow leading to vary with fontSize for this text'.
