Introducing Casilda - A Wayland compositor widget!
A simple Wayland compositor widget for Gtk 4 which can be used to embed other processes windows in your Gtk 4 application.
It was originally created for Cambalache's workspace using wlroots, a modular library to create Wayland compositors.
Following Wayland tradition, this library is named after my hometown in Santa Fe, Argentina
