PDF::Writer 1.1.3 is not the most recent version. I believe that Greg
and Michael fixed some font bugs.

Your expectation (of being able to embed EPS or another PDF) is
unrealistic given the reality of the internal implementation of PDF.
If you can grab the drawing instructions from an EPS (not hard, and
can be programmed), you can insert them directly into an object stream
on a PDF. (I've actually done this, manually.)
