 want to read the document in reverse order, since the base features
 are discussed under version 1.
 
-New Features in Theme Format Version 3.4
-========================================
-
-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
-the GTK+ theme, and <fallback> provides an alternative color definition
-in case the color referenced by <name> is not found.
-
-New Features in Theme Format Version 3.3
-========================================
-
-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
-differently ("tiled_left", "tiled_right", "tiled_left_and_shaded",
-"tiled_right_and_shaded").
-
-New Features in Theme Format Version 3.2
-========================================
-
-A new window type 'attached' is added for modal dialogs which are
-attached to their parent window. (When the attach_modal_dialogs preference
-is turned on.) If no style is defined for the 'attached' window type,
-the 'border' window type will be used instead.

 New Features in Theme Format Version 3.1

-  <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>
