This may be missing the point somehow, but if you used some kind of
"outlining" program (followed by a little editing) that creates a
vector-based (instead of bitmap based) image, you could then scale to
whatever size you want with perfect resolution, and then convert that
size to a bitmap format like JPG.  If you save the vector version, you
can scale-and-save-out to as many sizes as you like.

Back in the day I used Adobe Streamline for this kind of task, but I
don't know if that even still exists any more.
