Does that mean that you'd like to set the hscoll when the window is
smaller than the images so that the center of the image is displayed at
the center of the window?
Hm, this could at least be done once when initially opening some
document. When switching pages, the current hscroll is preserved and I
consider that a good thing. It shouldn't re-center then.

I know there were some issues/errors when the image of a page isn't
there already. That should be fixed by this version of the patch.
