If some device has a popped up menu, meta_frame_get_flags()
returns 0 to indicate other devices cannot trigger any
actions on the frame.

+
+2.91.3
+======
+
+* 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
+   [Derek, Owen, Thomas]

+An additional color type is added to pick up custom colors defined
+in the GTK+ theme's CSS:
+
+  gtk:custom(name,fallback)
+
+where <name> refers to a custom color defined with @define-color in

   <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>
