Mutter3.29.1

Mutter is a window and compositing manager that displays and managesyour desktop via OpenGL. Mutter combines a sophisticated displayengine using the Clutter toolkit with solid window-management logicinherited from the Metacity window manager.

While Mutter can be used stand-alone, it is primarily intended to beused as the display core of a larger system such as GNOME Shell. Forthis reason, Mutter is very extensible via plugins, which are usedboth to add fancy visual effects and to rework the window managementbehaviors to meet the needs of the environment.
