Yeah its not trivial.

I remember long discussions about the best implementation on Perl-community.de back in the days.  

IIRC it wasn't perfect because line height could differ. (UPDATE wrapping comes also into play here)

update

See this example listing on Perl-Community - tinita be praised for her implementation. :)
