Bump version to 2.29.1

That is, don't consider the state of num lock, xkb group number, etc,
when looking up keybindings.

+
+       GtkStyle is specific to a particular colormap. Metacity
+       uses different colormaps for windows with different
+       visuals, so it must specialize the GtkStyle.
+
+       Closes #568365 and #513944.
+
+       * src/ui/frames.[ch]: Keep a GtkStyle for each MetaUIFrame, which is
+         obtained by calling gtk_style_attach() on the style for the
+         MetaFrames. When the style of the MetaFrames changes, reattach
+         everything. When we call gtk_style_set_background() pass in the
+         right style.
+
+       * src/ui/themes.[ch]: Create a _with_style() variant of functions that
+         previously took the style from widget->style passed in, so we
+         can draw with the right style for the colormap.

 ===
 
-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>

-<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>

-<title>Actually drawing stuff</title>
-
-<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>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>

-   Metacity is a simple compositing window manager that integrates nicely with GNOME 2.
-</shortdesc>
- <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;

+ * SECTION:MutterTextureTower
+ * @short_description: mipmap emulation by creation of scaled down images
+ *
+ * A #MutterTextureTower 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.)

+/**
+ * MutterWindowGroup:
+ *
+ * This class is a subclass of ClutterGroup with special handling for
+ * MutterWindow when painting the group. When we are painting a stack
+ * of 5-10 maximized windows, the standard bottom-to-top method of
+ * drawing every actor results in a tremendous amount of overdraw
+ * and can easily max out the available memory bandwidth on a low-end
+ * graphics chipset. It's even worse if window textures are being accessed
+ * over the AGP bus.
+ *
+ * The basic technique applied here is to do a pre-pass before painting
+ * where we walk window from top to bottom and compute the visible area
+ * at each step by subtracting out the windows above it. The visible
+ * area is passed to MutterWindow which uses it to clip the portion of
+ * the window which drawn and avoid redrawing the shadow if it is completely
+ * obscured.
+ *
+ * A caveat is that this is ineffective if applications are using ARGB
+ * visuals, since we have no way of knowing whether a window obscures
+ * the windows behind it or not. Alternate approaches using the depth
+ * or stencil buffer rather than client side regions might be able to
+ * handle alpha windows, but the combination of glAlphaFunc and stenciling
+ * tends not to be efficient except on newer cards. (And on newer cards
+ * we have lots of memory and bandwidth.)
