justify text

if we had a stringwidth function like some xtalks and once was there via an 
xcmd, it could be done but slow...its was a key part of Postscript to do full 
justification...you have to space words and letters recursively to do 
right..its math and cpu intenstive. I would love to see more Postscript like functions 
in Transcript..been wanting this stuff for many years ;-)
