Comment:

 The proposed `sizedText` function can also be viewed as a generalization
 of the already existing `zeroWidthText` function, except with arbitrary
 sizes not just `0`. In this case we can define:

 {{{
     zeroWidthText = sizedText 0
 }}}

 or just export `sizedText` to cover both use cases.
