[Lazarus] Marking columns in synedit

[Mark Morgan Lloyd]

Is there an easy way of setting columns to a different background and/or 
foreground colour?

I've got two synedits, one in a main window with "music ruled" coloured 
lines and a small one above it numbered for columns, provided that the 
fount etc. is the same the relative positioning is correct. I'd like to 
be able to highlight header columns to mark tab positions, it's safe to 
assume that all visible character positions will contain a digit or a space.
