Feature request: slideshow for wallpapers

[Rhialto]

Currently it seems that if you use an option to set the desktop image / screen background /wallpaper, such as --bg-max, then feh exits immediately. In particular, options line --slideshow-delay are ignored.

What I would like is a wallpaper that changes every 5 minutes, randomly.

With the (very old) xv image viewer, I used xv -root -rmode 4 -maxpect -random -wait 300 -wloop -flist wallpaper-list for this.

This also has another feature that feh is missing (the -rmode 4): the image is scaled and centered like --bg-max, but to fill the potentially empty borders it is tiled as well.
