@code{Y-extent} it is assumed that this will trigger line breaking
calculations too early during compilation. So the function is not

must always still be the grob but the second and third are @q{start}

@q{unpure} and @q{pure} parts can be used, by only changing the number
of arguments passed to, and the scope of, the function.
