This is what PfaEdit does.

Essentially the parser handles the codes from both type1s and type2s. You 
need to do a little extra set up (the subroutine table needs to include its 
base offset (which is 0 for type1s and approximately cnt/2 for type2s).

The places where I actually check the type1/2 flag are:
   * numbers starting with 255
   * Needed a special check for paths containing single points when doing a
        closepath
   * Special check in the first *moveto for the width argument.
