One hint - it's not perfect. I've never looked into it, but I've also
never seen anything exactly aligned. I think mapnik's text placement
within shields is a fraction of a pixel off so the kind of sub-pixel
precision you're chasing isn't going to work. Maybe it's possible to
make the images slightly shifted but again I haven't tried.

Cheers,
