Thinking about the issue again, I fear that what I said in a former
message was wrong.  In order to *insert* a Type3 font into a PDF
file, no PostScript interpreter is needed, of course.

The Type3 format doesn't support hinting, hence Type3 fonts always
look extremely ugly at low resolutions.  I suppose that FontForge can
convert Type3 to Type1 and apply hints automatically.

Is there any reason not to go this way?  The conversion has to be done
only once.

Regards,
  Reinhard
