I've committed my patch now.  Evgeni, please report back if it really
solves the issue for you, so that I can close this issue.

Stefan, do you think the horizontal centering of images in case the
window is wider than the image should be customizable?  Currently it's
not which is fine with me and is what other viewers also do.
