Stop... the Prolog is copied verbatim from a file, and everything 
between the end of the DSC comments and the %%EndProlog comment should 
be exactly the same between runs of the tool.  If we need a fudge factor 
applied to the size of the text, then that can be done too.  There is a 
much better place to do so.  It's in the text output routine.  There, a 
calculation is done to scale the internal measure of the text size 
'points' to the postscript units.  This is the logical choice for such a 
change, it keeps the information together in one place.  Imagine someone 
later coming to try to figure out why his/her text comes up strange 
sizes and not being able to find where the scaling is occurring...

Note also, that there is the possibility that the text is also output as 
vectors, changing scale there might be a bit more difficult, as it uses 
the primitive line drawing routines to render the text.
