I've tried it, indeed it works much better. Might it be possible to store the the "native" size, and raise the resolution automatically when the zoom exceeds it?

On a side note, might it be also possible to horizontally center the image? There is a pretty straight-forward way to do it, used in the about-emacs screen.

You mean, it up-scales when you hit +? That's a feature, because
up-scaling is much faster than reconverting. To make use of the
feature, you should set `doc-view-resolution' to some reasonably high
value. I use this

(setq doc-view-resolution 200)

and it works very well.
