That's because `scroll-other-window' calls scroll-up/down in the other
window, but if the other window contains an doc-view buffer it should
ideally call image-scroll-up/down.

The only good solution I see is to define buffer local variables
`scroll-up-function' and `scroll-down-function' which are used by
`scroll-up' and `scroll-down' and then binding them appropriate in each
mode.

Anyway, that's not really related to doc-view.  All non-text modes are
pertained here.  Comments?

Bye,
