I intend to orphan the wayfire-shadows package as I no longer use software
from WayfireWM ecosystem.

The package description is:
 Wayfire is a 3D Wayland compositor, inspired by Compiz and based on
 wlroots. It aims to create a customizable, extendable and lightweight
 environment without sacrificing its appearance.
 .
 By default, the plugin will add fast and nice shadows around windows
 that use server side decorations. Additionally there is an option to
 make the focused window glow.
