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...
