hydrapaper - 2.0.2-1+deb11u1 main

HydraPaper is a GTK-based utility that sets background images for multiple
monitor desktops independently.
.
It works by merging multiple wallpaper images into one and setting the result
as wallpaper with the "Spanned" option.
.
It is based on the GNOME 3 Desktop but officially supports MATE and Budgie
as well, and should work on any GNOME-based desktop like Pantheon.
