non-existent ACI font substition issue

[Don <dlarson@cgmlarson.com>]

There seems to be an issue regarding what the viewer should 
do when when a substitution of a non-existent font occurs in 
an ACI file. For example, the CGM contains a Helvetica font and 
the ACI specifies that "Bogus" is to be substituted for Helvetica 
but "Bogus" font does not exist on the users system.  

 <fontMap>
   <maplist forceSubstitution="yes"
     cgmFont="Helvetica"
    substitutionList="Bogus"/>
 </fontMap>


What to do, ignore this substitution or use defaultFont?
