About Mutter
============

Mutter is a window and compositing manager that displays and manages
your desktop via OpenGL. Mutter combines a sophisticated display engine
using the Clutter toolkit with solid window-management logic inherited
from the Metacity window manager.

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

Changes since 2.91.2
====================
 * Better shadows: [Owen]
   - Shadows can be different for different window types and focus states
   - Shadows are larger by default, especially for the currently active
     window
   - Shadows for attached modal dialogs and menus are drawn not to
     overlap the attachment point.
   - Shadows follow the shape of shaped windows
 * Optimization: [Owen]
   - Avoid repainting in situations when windows are potentially restacked
     but aren't actually restacked.
   - Pay attention to partial stage repaints in obscured window calculations
   - Better optimization of painting obscured shadows; turn off shadows
     for maximized windows.
   - Move background repainting into Mutter; doing it here rather than
     in plugins allows not painting obscured parts of the background.
 * A new frame type 'attached' is added for attached modal dialogs
   and can be referenced in theme files with a theme version of 3.2.
 * Fix updating key bindings when the keyboard layout changes

 * Bug fixes [Adel, Florian]
 * Build fixes [Dan Williams, Diego, Javier, Owen]
