I can't work out what you are trying to say.
The changes are only in the printing code path.

However what it looks like to me is that Prasanta is now using 
TextLayout for printing only under
the same conditions as we use it on screen -- which is when 
"international" text is being rendered.
This will reintroduce clipped text bugs which the existing code was 
meant to fix so I don't think it
can be right.

It may not be pretty or a complete solution but I think we need to look 
at breaking the text into
the leading spaces + the rest of the trimmed string and using the screen 
advance of the
leading spaces to position the rest of the justified text.
