Remove all support for the metacity format

Browse Source 
Rest in peace you magnificent format, love-child of arcane X11 drawing
API and markup craze, you will not be missed.
We do remember however the bravery of a many men and women, who fearlessly
descended into the guts of your intrinsics and turned ugliness into beauty;
their work will still be spoken of when you will long have been forgotten.

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.

icon_height - height of large icon
title_width - width of title text
title_height - height of title text

For each piece, a draw_ops can be given inline or referenced

For each piece, the "width" and "height" variables in
coordinate expressions refers to the dimensions of the piece,
the origin is at the top left of the piece.
So <rectangle x="0" y="0" width="width-1" height="height-1"/>

entire_background: whole frame
titlebar: entire area above the app's window
titlebar_middle: area of titlebar_background not considered
part of an edge
left_titlebar_edge: left side of titlebar background
right_titlebar_edge: right side of titlebar background
top_titlebar_edge: top side of titlebar background
bottom_titlebar_edge: bottom side of titlebar background
title: the title area (doesn't include buttons)
left_edge: left edge of the frame
right_edge: right edge of the frame
bottom_edge: bottom edge of the frame
overlay: same area as entire_background, but drawn after
drawing all sub-pieces instead of before

<!-- For buttons, drawing methods have to be provided for
each of three states:
normal, pressed, prelight
and the button function or position must be provided:
close, maximize, minimize, menu,
left_left_background, left_middle_background,
left_right_background, right_left_background,
right_middle_background, right_right_background
So a working theme needs 3*4 = 12 button declarations
and a theme may have up to 3*10 = 30 button declarations
in order to handle button-rearrangement preferences.

background values existed.)
