  Description     : Modern wallpaper daemon for Wayland

wpaperd is the modern wallpaper daemon for Wayland. It dynamically changes the current wallpaper, either after a certain amount of time or via a command-line interface. It uses OpenGL ES to render the images and have beautiful hardware-accelerated transitions, while being easy on resources.

Notice: wpaperd uses wlr_layer_shell wayland protocol, which is available on all wlroots based compositors (sway, hyprland, ...) and on KDE. Therefore it won't work on GNOME.
Features

    Different wallpaper for each display
    Pick a wallpaper from a directory
    Change the wallpaper after a set time
    Multiple sorting methods (random or ordered)
    Flexible TOML configuration file
    Hot config reloading for all settings
    Easy to use command line interface
    Hardware-accelerated configurable transitions
    Multiple background modes (center, fit, fill)
    Easy on resources (low CPU and memory usage)

----

similar to wallutils in the sense that it is better to what we already
have but different because (a) it's in Rust and (b) it's a daemon
instead of one-shot utilities.
