Maybe Mathematica, with all its new typesetting wonders, can still pull
this off; but I am having my doubts.

Other languages offer a simple expedient.  They provide a call such as
TextWidth(str) that returns the width in pixels of a string 'str' --
assuming a particular font, style, and font size.  I could use such a
call to parse my string, letter by letter, until I knew the position of
each.

The call is nontrivial when you think about it in terms of kerning.  You
can't just add up all the letter widths, because they vary with the
particular string. I don't know whether Mathematica offers any such
function.

If not, it should!  It seems to have everything else.....
