There is some extra offset for lilypond-book (via `eps-box-padding'
IIRC).  Unfortunately, the bbox calculation within LilyPond has
problems; for example, beams are not correctly taken into account -- I
think there is a bug report already for this.

If you really need the tightest PNG image possible, I suggest to use
margins on all sides, then using a different program like `pnmcrop' to
remove the borders.

Correct.
