Well, it looks like I may have figured this out.  My PNG images are
74x74 dpi.  The conversion stuff is expecting 72x72 (I think).

If I convert the images with ImageMagic using:

convert -density 74 foo.png foo.epdf

The image quality is right.

Somebody correct me if this sounds too weird to be happening this way...
