[Lazarus] Column ruler above a synedit

[Mark Morgan Lloyd]

Is there a preferred way of putting a column ruler above the text in a 
synedit, either (two lines) marking columns or (one line) marking tab 
positions?

I've previously done this for a file viewer oriented towards large files 
with columnar text (e.g. database query output) by having two synedits 
on the same form, but since the ruler doesn't really want line numbers 
keeping the two lined up was not entirely reliable.
