Bump version to 2.91.3

A direction parameter is passed to meta_compositor_switch_workspace(),
to indicate the direction of the switch depending on the workspace
layout.
In contrast to the switcher popup, this parameter does not take the
text direction of the locale into account. Change this, so that the
workspace switching animations move in the correct direction.

-SHRINKING METACITY
+MUTTER FEATURES
 ===
 
-Not that metacity is huge, but a substantial amount of code is in
-preferences handling, in static strings that aren't essential, and in
-the theme engine.
-
-You can strip about 70K from the metacity binary by compiling with 
-options such as:
-
- --disable-gconf
- --disable-sm
- --disable-verbose 
- --disable-startup-notification
-
-However the result is no good for desktop use, all prefs have to be
-hardcoded in the binary, for example. If you wanted to make a really
-small metacity, here's some additional stuff you might consider
-implementing:
- 
- - add --disable-themes, which would replace theme.c and theme-parser.c 
-   with a hardcoded implementation of the interface in theme.h, 
-   should save about 80K. This should be fairly easy.
-
- - add --disable-gtk, which would implement the interface in ui.h
-   without using GTK. This one is easier than you think because the
-   main part of the window manager doesn't use GTK directly, but is
-   still fairly hard to do.  You would probably have to give up some
-   of the features, such as window menus, as menus are pretty complex
-   to implement well.  So time may be better spent adding a GTK
-   configure script feature to build GTK with only a small core set of
-   functionality.

-<para>This is an article about how to theme Metacity.  It is a work in progress, and I have had to dig deeply to find some answers; I may well have made mistakes and I welcome corrections and suggestions.</para>
-<para>GNOME lets you theme a bunch of different things, but we're only talking about <literal>window border</literal> themes here, which some people call Metacity themes; <ulink url="http://en.wikipedia.org/wiki/Metacity#Themes">Wikipedia begins a sentence</ulink> with &quot;Despite the incomplete state of Metacity theme development documentation&quot;, and though there <emphasis>is</emphasis> <ulink url="http://svn.gnome.org/viewvc/metacity/trunk/doc/theme-format.txt?view=markup">documentation in the source</ulink>, apparently not many people find it, and it's written more for programmers than theme designers.  Glynn Foster also wrote <ulink url="http://developer.gnome.org/doc/tutorials/metacity/metacity-themes.html">a very good introduction to Metacity themes</ulink> (<ulink url="http://home.arcor.de/rybaczyk/documents/tutorials/metacity/metacity-themes.de.html">[de]</ulink>) six years ago, but things have changed a little since then.  <ulink url="http://lists.freedesktop.org/archives/compiz/2006-September/000445.html">Metacity themes can also be used by Compiz</ulink>, and perhaps by other window managers for all I know.</para>
-
-<para>So, a Metacity theme is a set of instructions about how to &quot;decorate&quot; (draw the borders around) a window.  Presumably you don't want to style all windows identically, so the format lets you specify details for different kinds of window:</para>

X also allows a window to explicitly ask to be undecorated, but of course we don't provide for those in a list of decoration instructions.</para></listitem>

-<para>where <varname>N</varname> is the name of the theme and <varname>V</varname> is the version of the format.  Version 2, <ulink url="http://svn.gnome.org/viewvc/metacity?view=revision&amp;revision=2973">introduced in October 2006</ulink>, adds a few extra features, but it's rarely used.  Version 1 is the original format.  The formats are fixed once they're stable for both backwards and forwards compatibility; <ulink url="http://bugzilla.gnome.org/show_bug.cgi?id=482165">new features</ulink> can't be added without introducing a new version number, which is why improvements come out rarely and in large clumps.  <literal>metacity-1</literal> in the names is a fossil and doesn't mean version 1 of anything.</para>
-
-<para>The metacity-theme-V.xml files are <ulink url="http://blogs.gnome.org/tthurman/2008/02/14/gmarkup/">GMarkup files</ulink>, which are very similar to XML.  For now, you actually have to write these in a text editor or something; you can either start with a blank page, or modify a theme someone else has made.  (I am thinking of writing a general theme editor program, but that'll have to wait until I've reduced Metacity's open bug queue a little.)  If you want to see a fully-fledged one, you can look at <ulink url="http://svn.gnome.org/viewvc/metacity/trunk/src/themes/Atlanta/metacity-theme-1.xml?view=markup">the current version of &quot;Atlanta&quot;</ulink>, one of the simplest themes, but even that is quite complicated-looking at first.</para>
-<para>So, let's talk about what actually goes inside the files.  As in any XML file, &lt;!-<!-- x -->- &#8230; <!-- x -->&gt; are comments.  At its most basic, it would go:</para>

-</variablelist>
-</para>
-
-<para>
-<varname>N</varname> is the name of a <literal>frame_style</literal> to apply to a window which has these attributes.</para>
-
-<para>A <literal>frame_style_set</literal> tag may also have a &quot;parent&quot; tag, which should be the name of another <literal>frame_style_set</literal>. This means that if Metacity wants to know about a kind of window which that <literal>frame_style_set</literal> doesn't describe, it should look in the parent.  Most of the more complicated tags in Metacity theme files also have a &quot;parent&quot; attribute which work the same way.  This is particularly useful because, taken together, all the <literal>frame_style_set</literal>s in a theme file must be capable of matching every possible kind of window; if a window turns up that they can't match, there will be an error at runtime.</para>
-
-<para>Let's recap what we've seen so far. The combination of a <literal>window</literal>, which matches a window's state (normal, dialog, and so forth), with an entry in the corresponding <literal>frame_style_set</literal>, which matches its focus, shadedness, maximisedness, and resize permissions where relevant, will allow you to make a list of rules to match any window against.  The next piece of this puzzle lets you specify what Metacity should do with such windows once it's matched them.</para>

-<para><literal>frame_style:</literal> This is probably the most complicated part of the whole system. A <literal>frame_style</literal> a series of <emphasis><literal>piece</literal></emphasis>s and <emphasis><literal>button</literal></emphasis>s.  It looks like this:</para>
-
-<para>
-<programlisting>
-&lt;frame_style name=&quot;&#8230;&quot; geometry=&quot;G&quot;&gt;
-&lt;piece position=&quot;P&quot;&gt;

-
-&lt;draw_ops&gt;
-&lt;/draw_ops&gt;
-&lt;/button&gt;
-&#8230;
-&lt;/frame_style&gt;
-</programlisting>
-</para>
-
-<para>The <literal>pieces</literal> are pieces of the window frame.  When Metacity draws a window frame, it renders its various pieces always in the same order.  The bolded parts are all the possible values of P:</para>
-
-<para>
-<itemizedlist>
-<listitem><para>the <literal>entire_background</literal>, covering the whole frame</para></listitem>
-
-<listitem><para>the <literal>titlebar</literal>, covering the entire background of the titlebar</para></listitem>
-<listitem><para>the <literal>titlebar_middle</literal>, the part of the titlebar that doesn't touch its edges</para></listitem>
-<listitem><para>the <literal>left_titlebar_edge</literal>, <literal>right_titlebar_edge</literal>, <literal>top_titlebar_edge</literal>, and <literal>bottom_titlebar_edge</literal></para></listitem>
-
-<listitem><para>the <literal>title</literal>, just exactly that area which is covered by the text on the titlebar</para></listitem>
-<listitem><para>the <literal>left_edge</literal>, <literal>right_edge</literal>, and <literal>bottom_edge</literal> of the frame (yes, there is no top_edge: it's identical to top_titlebar_edge, isn't it?)</para></listitem>
-<listitem><para>the <literal>overlay</literal>, which covers everything&#8211; the same as entire_background, but done last instead of first.</para></listitem>
-</itemizedlist>
-</para>
-
-<para><emphasis>What</emphasis> Metacity draws in these pieces is decided by the theme.  If a <literal>frame_style</literal> or its parents don't specify a particular piece, nothing will be drawn for that piece.  You have two ways to specify what to draw: one is that the <literal>piece</literal> tag can have a <literal>draw_ops</literal> tag inside it which lists a sequence of drawing operations in Metacity's custom format.  <ulink url="http://bugzilla.gnome.org/show_bug.cgi?id=107012">You might ask why we don't use SVG</ulink>; one answer is that SVG support wasn't very strong when this format was designed, and another answer is that these days you can use SVG all you like; just include it as an image and Metacity will know what to do.</para>
-
-<para>An alternative to including a draw_ops tag inside a piece tag is to add a draw_ops attribute to the piece tag.  Then you can add a draw_ops tag at top level (inside the metacity_theme tag) with a name attribute, and Metacity will use that.  This is useful if you use similar draw_ops over and over.</para>
-<para>I'm not going to document draw_ops at present, because this is already very long.  I will write it up later and link it from here.</para>
-<para>The <literal>button</literal> tag tells Metacity how, but not where, to draw buttons.  Buttons are drawn after all the pieces are finished, and the way to draw them is also given using draw_ops.  You ought to provide buttons for all the possible kinds of button; if you don't give one it won't be drawn, which is unfortunate for the user who wants to use it:</para>
-
-<para>
-<itemizedlist>
-<listitem><para><literal>left_left_background</literal>, <literal>left_middle_background</literal>, and <literal>left_right_background</literal> don't represent buttons as such, but the background behind them, assuming there can be at most three buttons on the left.  These days there can be more, so the extra ones also use left_middle_background.</para></listitem>
-
-<listitem><para><literal>right_left_background</literal>, <literal>right_middle_background</literal>, and <literal>right_right_background</literal> similarly.</para></listitem>
-<listitem><para><literal>close</literal>, <literal>minimize</literal>, <literal>maximize</literal> are the obvious original three buttons.</para></listitem>
-<listitem><para><literal>menu</literal> is the menu button you can click to get a list of actions you can perform on the window.</para></listitem>
-
-<listitem><para><literal>shade</literal>, <literal>above</literal>, <literal>stick</literal> are similar to the original buttons but only allowed in version 2</para></listitem>
-<listitem><para><literal>unshade</literal>, <literal>unabove</literal>, <literal>unstick</literal> are the toggled versions of these buttons.  Again, version 2 only.</para></listitem>
-
-</itemizedlist>
-</para>
-
-<para>The reason there are toggled versions of shade, above, and stick, and not maximize, is that by the time you get this far you've probably already decided whether you're drawing a maximised window.  So if you <emphasis>are</emphasis> drawing a maximised window, you can make the button called &quot;maximize&quot; look how you want the restore button to be; otherwise, make it look like you want the maximise button to be.</para>
-<para>For each button tag you should also set a &quot;state&quot; attribute; this time the state is either <literal>normal</literal> (the way you see it most of the time), <literal>pressed</literal>, or <literal>prelight</literal> (this makes the buttons subtly light up when you hover over them).  You only really need &quot;normal&quot;, but the others are good to have too.</para>
-
-<para>The &quot;geometry&quot; attribute of a <literal>frame_style</literal> tag is the name of a&#8230;</para>
-
-</chapter>
-
-<chapter>
-<title>Geometry</title>
-
-<para>The <literal>geometry</literal> tag defines the sizes of things around the window.  It is important, but not easy to explain, and again this file has gone on too long.  I'll write it up later.</para>
-
-</chapter>
-
-<chapter>
-<title>Other things which lie around a file</title>
-
-<para>The most important other thing in a theme file is the metadata held in the <literal>info</literal> tag.  This contains a set of tags each of which contains some text explaining something about the theme itself, in a sort of <ulink url="http://en.wikipedia.org/wiki/Dublin_Core">Dublin Core</ulink> sort of way.  (Next time around, we should probably use the actual Dublin Core.)  The tags are <literal>name</literal>, <literal>author</literal>, <literal>copyright</literal>, <literal>date</literal>, and <literal>description</literal>.</para>
-
-<para>Version 1 of the format had a <literal>menu_icon</literal> tag at top level, which let themes specify the icons beside options in the menu you get from the menu icon.  This has become redundant; the icons are taken from the icon theme!  The tag can still be used in all formats, but does nothing and is deprecated.</para>
-<para>Version 2 of the format has a <literal>fallback</literal> tag at top level, which let the theme specify what icon a window should be considered to have if it doesn't provide an icon of its own.  This should also be taken from the icon theme, <ulink url="http://bugzilla.gnome.org/show_bug.cgi?id=524343">if anyone fancies fixing it</ulink>, and the tag should also then be deprecated.  It shouldn't be hard.</para>

-<para>When you're editing a theme, you can view it without using it on the whole desktop using
-<command>metacity-theme-viewer YourThemeName</command></para>
-<para>and view it on the whole desktop using
-<command>gconftool -<!-- x -->-type=string -<!-- x -->-set /apps/metacity/general/theme YourThemeName</command></para>
-
-<para>Whenever you change the selected theme in GConf, Metacity will load the newly-chosen theme.  This is how control-center does it.  But when you change a theme, as you're working on it, you might want to ask Metacity to reload the theme which is currently used on the whole desktop to reflect your changes.  You can do this using the little-known <command>metacity-message</command> program, with the command <literal>metacity-message reload-theme</literal>.  This works by sending the ClientMessage <literal>_METACITY_RELOAD_THEME_MESSAGE</literal> to the root window, in case you're interested.</para>
-
-<para>Once you're done with your theme, consider submitting it to <ulink url="http://art.gnome.org/themes/metacity/">the art.gnome.org site</ulink>, or <ulink url="http://www.gnome-look.org/index.php?xcontentmode=101">the gnome-look site</ulink>.</para>

-<title>The future</title>
-
-<para>Please feel free to link to this so people don't have to keep asking the basic questions and can start asking the deeper ones.  One of the important deeper ones is: where should we go in the future?  Since this format is becoming something of a de facto standard between window managers, should we set up some kind of freedesktop.org standards discussion?  Would it be useful to spin off Metacity's theme parsing code into a separate, LGPL-licensed library so that other applications could use it more easily?</para>
-<para>What would a version 3 of this format look like?  Could we simplify the window / frame_style_set system? (I can imagine abolishing both, and being able to write <literal>&lt;frame_style for=&quot;normal+unfocused+maximized&quot;&gt;&#8230;</literal> and having Metacity assume it applied to all resize permissions and shadednesses.) Maybe we should try to do everything with SVG we can? Getting more wild and handwavey, is it worth keeping XML-like?  Maybe if other window managers were dealing with the files, .ini-style files would be more universally useful? Or perhaps not.  And then of course we need a decent graphical editor for it.  I have a few ideas, but if anyone fancies jumping in...</para>

@@ -21,6 +22,49 @@ 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 3.2
+========================================
+
+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

- <description xml:lang="en">
-A window manager for GNOME, with a focus on simplicity and usability
-rather than novelties or gimmicks.  It uses GTK+ 2 for drawing window frames,
-so that it inherits colours, fonts, and so on from the GTK+ theme.  Its author
-has characterised it as a &quot;boring window manager for the adult in you.
-Many window managers are like Marshmallow Froot Loops; Metacity is like Cheerios.&quot;

 msgid "Setting this option to false can lead to buggy behavior, so users are strongly discouraged from changing it from the default of true. Many actions (e.g. clicking in the client area, moving or resizing the window) normally raise the window as a side-effect. Setting this option to false, which is strongly discouraged, will decouple raising from other user actions, and ignore raise requests generated by applications. See http://bugzilla.gnome.org/show_bug.cgi?id=445447#c6. Even when this option is false, windows can still be raised by an alt-left-click anywhere on the window, a normal click on the window decorations, or by special messages from pagers, such as activation requests from tasklist applets. This option is currently disabled in click-to-focus mode. Note that the list of ways to raise windows when raise_on_click is false does not include programmatic requests from applications to raise windows; such requests will be ignored regardless of the reason for the request. If you are an application developer and have a user complaining that your application does not work with this setting disabled, tell them it is _their_ fault for breaking their window manager and that they need to change this option back to true or live with the \"bug\" they requested."
 msgstr "Selle valiku väärtuseks false määramine võib põhjustada vigast käitumist, nii on selle vaikimisi väärtuse true muutmine rangelt mittesoovitatav. Paljud tegevused (nt kliendialal klõpsamine, akna liigutamine või suuruse muutmine) tõstavad kõrvaltoimena akna. Selle väärtuseks false määramine, mis on rangelt mittesoovitatav, keelab akna tõstmise teiste kasutaja tegevuste peale ja ignoreerib rakenduste tõstmispäringuid. Vaata http://bugzilla.gnome.org/show_bug.cgi?id=445447#c6. Isegi kui selle valiku väärtus on false, saab aknaid tõsta tehes alt+vasakklõps suvalises kohas aknal, hariliku klõpsamisega aknaääristel  või eriteadetega lehesüsteemidelt, nagu aktiveerimispäringud rakenduste nimekirja rakendilt. See valik on praegu keelatud fokuseerimiseks-klõpsa režiimis. Akende tõstmise päringuid rakenduse seest eiratakse sõltumata päringu põhjusest. Kui sa oled arendaja ja mõni kasutaja kurdab, et rakendused ei tööta, kui see säte on keelatud, siis ütle neile, et see on _nende_ viga, et nad rikkusid aknahalduri ja neil tuleb selle valiku väärtuseks määrata uuesti \"true\" võib elada \"veaga\", mille nad ise põhjustasid."

+ * - We use the fact that a Gaussian blur is separable to do a

+ *   columns.
+ *
+ * - For better cache efficiency, we blur rows, transpose the image

+ * SECTION:MetaTextureTower
+ * @short_description: mipmap emulation by creation of scaled down images
+ *
+ * A #MetaTextureTower is used to get good looking scaled down images when
+ * we can't use the GL drivers mipmap support. There are two separate reasons
+ *
+ *  - Some cards (including radeon cards <= r5xx) only support
+ *    TEXTURE_RECTANGLE_ARB and not NPOT textures. Rectangular textures
+ *    are defined not to support mipmapping.
+ *  - Even when NPOT textures are available, the combination of NPOT
+ *    textures, texture_from_pixmap, and mipmapping doesn't typically
+ *    work, since the X server doesn't allocate pixmaps in the right
+ *    layout for mipmapping.
+ *
+ * So, what we do is create the "mipmap" levels ourselves by successive
+ * power-of-two scaledowns, and when rendering pick the single texture
+ * that best matches the scale we are rendering at. (Since we aren't
+ * typically using perspective transforms, we'll frequently have a single
+ * scale for the entire texture.)
