-Themes are in a simple XML-subset format. There are multiple versions
-of the theme format, and a given theme can support more than one format.
-
-Version 1:     THEMEDIR/metacity-1/metacity-theme-1.xml
-  (original metacity format)
-Version 2:     THEMEDIR/metacity-1/metacity-theme-2.xml
-Version 3:     THEMEDIR/metacity-1/metacity-theme-3.xml
-
-The subdirectory name is "metacity-1" in all versions.
-
-As you might expect, older versions of metacity will not understand
-newer theme formats. However, newer versions will use old themes.
-Metacity will always use the newest theme format it understands that
-the X server supports. Some format versions are only supported if you
-have the right X server features.
-
-Each format *requires* the corresponding filename. If you put version
-2 format features in the metacity-1/metacity-theme-1.xml file, then
-metacity will get angry.
-
-This document has separate sections for each format version. You may
-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
-========================================
-
-Additional predefined variables are added for positioning expressions:
-
- frame_x_center: the X center of the entire frame, with respect to the
-     piece currently being drawn.
- frame_y_center: the Y center of the entire frame, with respect to the
-     piece currently being drawn.
-
-The <title/> element now supports an "ellipsize_width" attribute. When
-specified, this gives a width at which to ellipsize the title. If not
-specified, the title will simply be clipped to the title area.
-
-New Features in Theme Format Version 3
-======================================
-
-Format version 3 has exactly one new feature; any element in the file
-can now have a version attribute:
-
-  version="[<|<=|=>|>] MAJOR.MINOR"
-
-(< and > should be to be entity escaped as &lt; and &gt;). If this
-version check is not met, then the element and its children will be
-ignored. This allows having alternate sections of the theme file for
-older and newer version of the Metacity theme format.
-
-When placed on the toplevel <metacity_theme> element, an unsatisfied
-version check will not just cause the contents of the file to be
-ignored, it will also cause the lookup of a theme file to proceed on
-and look for an older format 2 or format 1 file. This allows making a
-metacity-theme-3.xml file that is only used the format version 3.2 or
-newer is supported, and using metacity-theme-1.xml for older window
-managers.
-
-New Features in Theme Format Version 2
-======================================
-
-The optional attributes rounded_top_left, rounded_top_right,
-rounded_bottom_left and rounded_bottom_right on <frame_geometry>
-should now be the radius of the corner in pixels. You may still use
-the values "false" for 0 and "true" for 5, which means v1 values will
-still work just fine.
-
-<frame_geometry> has a new optional attribute, hide_buttons. If this
-is true, no buttons will be displayed on the titlebar.
-
-Anywhere you can use a positive integer, you can use an integer constant.
-
-As well as constant integers and reals, you may define constant colours,
-thus:
-  <constant name="RevoltingPink" value="#FF00FF"/>
-  <constant name="Background" value="gtk:bg[NORMAL]"/>
-
-<frame_style> has two new optional attributes, background and alpha.
-If you specify alpha, you must specify background. background is a
-colour used for the background of the frame. alpha is the transparency
-as a real between 0.0 and 1.0. If the current X server does not support
-alpha channels, the value is ignored.
-
-The filename attribute of <image> may begin with "theme:". If so, the
-rest of the string is the name of a theme icon. The 64x64 version of the
-icon is used, except for fallback mini_icons, which use the 16x16 version.
-This does not affect ordinary resizing. For example:
-  <button function="close" state="normal">
-    <draw_ops>
-      <include name="active_button"/>
-      <image filename="theme:gnome-logout" x="2" y="2"
-          width="width-4" height="height-4"/>
-      <!-- Note: not "theme:gnome-logout.png" or similar. -->
-    </draw_ops>
-  </button>
-
-<menu_icon>s are parsed but ignored.
-
-Fallback icons can be specified using <fallback>. There are two
-optional arguments, icon and mini_icon. The values of these arguments
-are identical to that of the filename attribute of <image>. Fallback
-icons are used when a window does not supply its own icon. If a fallback
-icon is not specified with <fallback>, Metacity will use a built-in
-icon, as in metacity-theme-1.
-
-The <arc> element, as well as the original start_angle and end_angle
-attributes, may be given from and to attributes. The values of these
-attributes are given in degrees clockwise, with 0 being straight up.
-For example:
-  <arc from="0.0" to="90.0" filled="true" color="#FF00FF"
-      x="0" y="5" width="15" height="15"/>
-
-<frame state="shaded"> may now take an optional resize attribute, with
-the same interpretation as the resize attribute on <frame state="normal">.
-If this attribute is omitted for state="shaded", it defaults to "both".
-(If it is omitted for state="normal", it remains an error.)
-
-In addition to the four <button> functions which are required in
-metacity-theme-1, there are six new functions in metacity-theme-2:
-shade, unshade, above, unabove, stick and unstick.
-
