that looks better than expected. Also, it shows the strange setup of
eog's statusbar (note the bevel being to short).

That's indeed an interesting usage of eog, I haven't heard before of.
I know some people use eog instead of evince to view their TIFF faxes,
which is why there's also a plugin providing zoom to width
functionality. But this is new to me. :)

Ah okay, that's a misunderstanding. That code was meant to show off that
recoloring eog's GUI works in certain situations already. This targeted
the feature that was requested in the bug you referenced in your last
mail. Adding this snippet to your gtk config will in fact change the
background color of the image collection widget (the thing with all the
thumbnails) and not the huge image viewing widget.

Don't worry about this. Although Claudio and me are having troubles
finding free time for eog for quite a long time now, we would've told
you if we were totally against it.

Also, putting it into a Bugzilla request ensures that it doesn't get
lost (which happens pretty quick on a mailing list). And even if we have
to postpone it, it might serve as a starting point for someone having
enough free time wishing to devote it to GNOME/eog. ;)

Talking of implementation, I made some short tests and it looks like the
stuff you need could be implemented in a small plugin for eog. That
would mean we likely won't have to touch eog's code and it won't hit
users not requiring that functionality (which was one of the reasons the
plugin API was created for eog).
