+========================================
+
+Add two additional button background functions - left_single_background and
+right_single_background - for button groups with just a single button.
+
+There are now additional frame states to style left/right tiled windows

   <shortdesc xml:lang="en">Window and compositing manager based on Clutter</shortdesc>
+  <description>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.</description>

-Plugins implement effects associated with WM events, such as window map,
-minimizing, maximizing, unmaximizing, destruction and workspace switching. The
-plugin API is documented in src/include/compositor-clutter-plugin.h; in
-addition the simple plugin can be used as a reference implementation.
-
-The API is intended to be generic, exposing no implementation details of the WM
-to the plugins; this will facilitate reuse without modification with another WM
-(there are plans to use the same plugin API with Matchbox 2).
-
-Multiple plugins can implement the same effect and be loaded at the same time;
-however, stacking arbitrary effects in this way might not work as expected;
-this is particularly true of more complex effects, such as those for workspace
-switching.
-
-Plugins are installed in ${prefix}/lib/metacity/plugins/clutter; from there the
-WM will load plugins listed in the clutter_plugins key in the Metacity gconf
-general preferences group. Each entry in preferences has the format
-
-  'name: optional parameters'
-
-where 'name' is the name of the library without the .so suffix.
-
-As noted above, additional parameters can be passed to the plugin via the
-preference key. In such case, the plugin name is immediately followed by a
-colon, separating it from the parameters. Two common parameters should be
-handled by all plugins:
-
-  'debug'   indicates that the plugin is run in a debug mode (what exactly that
-            means is left to the plugin to determine).
-
-  'disable' parameter indicates which effects within the plugin should be
-            disabled; the format of the disable parameter is
-
-              'disable: effect1[, effect2];'
-
