- wallpaper images should be of type svg, but png works too.
- wallpaper images should go into /usr/share/images/desktop-base/ (atm
/usr/share/wallpapers, which works too.)
artwork should provide a file named debian-edu.xml in
/usr/share/images/desktop-base/
(Example in case the wallpaper images are located in the same dir, otherwise
replace 'images/desktop-base' with 'wallpapers')

# file /usr/share/images/desktop-base/debian-edu.xml

Configure the background (should be done in postinst script of the
package, I guess):
update-alternatives --install
/usr/share/images/desktop-base/desktop-background.xml desktop-background.xml
/usr/share/images/desktop-base/debian-edu.xml 10
update-alternatives --install /usr/share/images/desktop-base/desktop-background
desktop-background
/usr/share/images/desktop-base/debian-edu-wallpaper01_1920x1080.png 75
Done manually, this seems to provide the Debian Edu desktop background
for new users.
