Just tried with revision 652228: the problem persists; steps to
reproduce are:
- F3
- zoom in (e.g. 1200%)
- F4  ==> the zoom in the album view is undone.

Well, I was not thinking of editing the image, but just
displaying it at its actual resolution from a certain zoom-level on.
I think Frank's suggestion in #16 would be a very good solution.

I think that this would be good to have.
(The quality of the interpolation is very good, but
to just judge the quality on the pixel-level alone
it would be good to have no interpolation - e.g for
gqview this corresponds to the "interpolation=nearest")
