295 is that "mmm" is much wider then "iiii", but the latter is a longer
296 string - thus the calculation can go wrong (doing it properly and putting
297 it into an DOM object and measuring that is horribly(!) slow). Thus as
298 a "work around" we provide this option. It will append its value to the
