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 2.91.4
====================
* Add a Above_Tab key symbol that can be used in key bindings to mean
  the key above the Tab key. This is now the default binding for
  cycle_group in both Mutter and Metacity. [Owen]
* Add new frame states for tiled-on-the-left and tiled-on-the-right [Florian]
* Add new background drawing functions that can be defined in a theme
  for single buttons. [Florian]
* Draw the right button backgrounds for all custom button layouts [Florian]
* Remove vestigal --composite/--no-composite command line options [Nickolas]
* Fix building on GLES [Andreas]
* Code cleanups [Adel, Owen]
