-
-1) Introduction
----------------
-
-This document details metacity compliance with the relevent standards.
-The format of this document is as follows:
-
-[-/+?] Hint Name/Feature Name (Version number)
-       Errata/Comments
-
-The first character indicates the level of compliance as follows:
-    -   none
-    /   partial
-    +   complete
-    ?   unknown
-
-The title indicates a feature or a hint in the specification, and the
-version number indicates the minimum version of the specification
-supported by metacity.  Later versions may be supported if no
-incompatible changes have been made in the specification.
-
-2) EWMH Compliance
-------------------
-
-The EWMH, or Extended Window Manager Hints is a freedesktop.org-
-developed standard to support a number of conventions for
-communication between the window manager and clients.  It builds on
-and extends the ICCCM (See Section 3).  A copy of the current EWMH
-standard is available at http://freedesktop.org/Standards/wm-spec/
-
-  a. Root Window Properties
-  -------------------------
-
-+ _NET_SUPPORTED (1.3)
-
-+ _NET_CLIENT_LIST (1.3)
-
-+ _NET_NUMBER_OF_DESKTOPS (1.3)
-
-+ _NET_DESKTOP_GEOMETRY (1.3)
-  Metacity does not implement large desktops, so this is kept set to
-  the screen size.
-
-+ _NET_DESKTOP_VIEWPORT (1.3)
-  Metacity does not implement viewports, so this is a constant (0,0).
-
-+ _NET_CURRENT_DESKTOP (1.3)
-
-+ _NET_DESKTOP_NAMES (1.3)
-
-+ _NET_ACTIVE_WINDOW (1.3)
-
-+ _NET_WORKAREA (1.3)
-
-+ _NET_SUPPORTING_WM_CHECK (1.3)
-
-+ _NET_VIRTUAL_ROOTS (1.3)
-  Metacity does not read or set this property, but it does not use
-  virtual roots to implement virtual desktops, so it complies with the
-  specification.
-
-+ _NET_DESKTOP_LAYOUT (1.3)
-
-+ _NET_SHOWING_DESKTOP (1.3)
-
-  b. Root Window Messages
-  -----------------------
-
-+ _NET_CLOSE_WINDOW (1.3)
-
-- _NET_MOVERESIZE_WINDOW (1.3)
-  Metacity supports this message, but the specification is unclear on
-  the layout of the detail value, and as such it is #if 0'd in the code
-
-+ _NET_WM_MOVERESIZE (1.3)
-
-- _NET_RESTACK_WINDOW (1.3)
-  Metacity will raise or lower windows in response to this message,
-  but the sibling restack modes are not supported, and it is currently
-  #if 0'd in the code.
-
-+ _NET_REQUEST_FRAME_EXTENTS (1.3)  
-
-  c. Application Window Properties
-  --------------------------------
-
-+ _NET_WM_NAME (1.3)
-
-+ _NET_WM_VISIBLE_NAME (1.3)
-  Metacity does not set this property, but metacity will never display
-  a name different from _NET_WM_NAME
-
-+ _NET_WM_ICON_NAME (1.3)
-
-+ _NET_WM_VISIBLE_ICON_NAME (1.3)
-  Metacity does not set this property, but metacity will never display
-  a name different from _NET_WM_NAME
-
-+ _NET_WM_DESKTOP (1.3)
-
-+ _NET_WM_WINDOW_TYPE (1.3)
-
-/ _NET_WM_STATE (1.3)
-  This property is read and updated according to the specification,
-  but see caveat below.
-  Metacity does not recognize separate vertical and horizontal
-  maximization states.  Currently metacity will do a two-dimensional
-  maximization if either property is set.
-  See: http://bugzilla.gnome.org/show_bug.cgi?id=113601
-  Metacity doesn't implement viewports so _NET_WM_STATE_STICKY is
-  unimplemented.
-
-+ _NET_WM_ALLOWED_ACTIONS (1.3)
-  Metacity keeps this hint up to date.  The code is somewhat crufty
-  and should be rewritten, though it is functional.
-  See: http://bugzilla.gnome.org/show_bug.cgi?id=90420
-
-+ _NET_WM_STRUT (1.3)
-
-+ _NET_WM_STRUT_PARTIAL (1.3)
-
-+ _NET_WM_ICON_GEOMETRY (1.3)
-  Metacity uses this property to draw minimize/restore animations
-
-+ _NET_WM_ICON (1.3)
-
-+ _NET_WM_PID (1.3)
-
-+ _NET_WM_HANDLED_ICONS (1.3)
-  Metacity does not read or set this property.  However, metacity
-  never manages iconified windows, and so has no need to do so.
-
-+ _NET_WM_USER_TIME (1.3)
-  Metacity uses this property to prevent applications from stealing
-  focus if supported by the toolkit.
-
-+ _NET_FRAME_EXTENTS (1.3)
-  If set in response to a _NET_REQUEST_FRAME_EXTENTS message received
-  prior to the window being mapped, this may be an estimate.  This is,
-  however, expressly allowed by the specification.

-Window managers have a few ways in which they are significantly different
-from other applications.  This file, combined with the code overview in
-doc/code-overview.txt, should hopefully provide a series of relatively
-quick pointers (hopefully only a few minutes each) to some of the places
-one can look to orient themselves and get started.  Some of this will be
-general to window managers on X, much will be specific to Metacity, and
-there's probably some information that's common to programs in general but
-is nonetheless useful.

-Administrative issues
-  Don't commit substantive code in here without asking hp@redhat.com.
-  Adding translations, no-brainer typo fixes, etc. is fine.
-
-  The code could use cleanup in a lot of places, feel free to do so.
-
-  See http://developer.gnome.org/dotplan/for_maintainers.html for
-  information on how to make a release.  The only difference from those
-  instructions is that the minor version number of a Metacity release
-  should always be a number from the Fibonacci sequence.
-
-Minimal Building/Testing Environment
-  You do not need to _install_ a development version of Metacity to
-  build, run and test it; you can run it from some temporary
-  directory.  Also, you do not need to build all of Gnome in order to
-  build a development version of Metacity -- odds are, you may be able
-  to build metacity from CVS without building any other modules.
-
-  As long as you have gtk+ >= 3.0 and GIO >= 2.25.10 with your distro
-  (gtk+ >= 2.6 if you manually revert the change from bug 348633), you
-  should be able to install your distro's development packages
-  (e.g. gtk2-devel, glib-devel, startup-notification-devel on
-  Fedora; also, remember to install the gnome-common package which is
-  needed for building cvs versions of Gnome modules like Metacity) as
-  well as the standard development tools (gcc, autoconf, automake,
-  pkg-config, intltool, and libtool) and be ready to build and test
-  Metacity.  Steps to do so:
-
-  $ svn checkout http://svn.gnome.org/svn/metacity/trunk metacity
-  $ cd metacity
-  $ ./autogen.sh --prefix /usr
-  $ make
-  $ ./src/metacity --replace
-
-  Again, note that you do not need to run 'make install'.
-
-Relevant standards and X properties
-  There are two documents that describe some basics about how window
-  managers should behave: the ICCCM (Inter-Client Communication Conventions
-  Manual) and EWMH (Extended Window Manager Hints).  You can find these at
-  the following locations:
-    ICCCM - http://tronche.com/gui/x/icccm/
-    EWMH  - :pserver:anoncvs@pdx.freedesktop.org:/cvs
-  The ICCCM is usually available in RPM or DEB format as well.  There is
-  actually an online version of the EWMH, but it is almost always woefully
-  out of date.  Just get it from cvs with these commands (the backslash
-  means include the stuff from the next line):
-    cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/icccm-extensions login
-    cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/icccm-extensions \
-      checkout wm-spec
-
-  DO NOT GO AND READ THOSE THINGS.  THEY ARE REALLY, REALLY BORING.
-
-  If you do, you'll probably end up catching up on your sleep instead of
-  hacking on Metacity. ;-)  Instead, just look at the table of contents and
-  glance at a page or two to get an idea of what's in there.  Then only
-  refer to it if you see something weird in the code and you don't know
-  what it is but has some funny looking name like you see in one of those
-  two documents.
-
-  You can refer to the COMPLIANCE file for additional information on these
-  specifications and Metacity's compliance therewith.
-
-  One of the major things those documents cover that are useful to learn
-  about immediately are X properties.  The right way to learn about those,
-  though, is through hand on experimentation with the xprop command (and
-  then look up things you find from xprop in those two manuals if you're
-  curious enough).  First, try running
-    xprop
-  in a terminal and click on one of the windows on your screen.  That gives
-  you the x properties for that window.  Look through them and get a basic
-  idea of what's there for kicks.  Note that you can get rid of some of the
-  verboseness by grepping out the _NET_WM_ICON stuff, i.e.
-    xprop | grep -v _NET_WM_ICON
-  Next, try running
-    xprop -root
-  in a terminal.  There's all the properties of the root window (which you
-  can think of as the "main" Xserver window).  You can also manually
-  specify individual windows that you want the properties of with
-    xprop -id <id>
-  if you know the id of the window in question.  You can get the id of a
-  given window by either running xwininfo, e.g.
-    xwininfo | grep "Window id" | cut -f 4 -d ' '
-  or by looking at the _NET_CLIENT_STACKING property of the root
-  window.  Finally, it can also be useful to add "-spy" (without the
-  quotes) to the xprop command to get it to continually monitor that
-  window and report any changes to you.
-
-Debugging information
-  Trying to run a window manager under a typical debugger, such as gdb,
-  unfortunately just doesn't work very well.  So, we have to resort to
-  other methods.
-
-  Debugging logs
-
-  First, note that you can start a new version of metacity to replace the
-  existing one by running
-    metacity --replace
-  (which also comes in handy in the form "./src/metacity --replace" when
-  trying to quickly test a small change while hacking on metacity without
-  doing a full "make install", though I'm going off topic...)  This will
-  allow you to see any warnings printed at the terminal.  Sometimes it's
-  useful to have these directed to a logfile instead, which you can do by
-  running
-    METACITY_USE_LOGFILE=1 metacity --replace
-  The logfile it uses will be printed in the terminal.  Sometimes, it's
-  useful to get more information than just warnings.  You can set
-  METACITY_VERBOSE to do that, like so:
-    METACITY_VERBOSE=1 METACITY_USE_LOGFILE=1 metacity --replace
-  (note that METACITY_VERBOSE=1 can be problematic without
-  METACITY_USE_LOGFILE=1; avoid it unless running in from something that
-  won't be managed by the new Metacity--see bug 305091 for more details).
-  There are also other flags, such as METACITY_DEBUG, most of which I
-  haven't tried and don't know what they do.  Go to the source code
-  directory and run
-    grep "METACITY_" * | grep getenv
-  to find out what the other ones are.
-
-  Adding information to the log
-
-  Since we can't single step with a debugger, we often have to fall back to
-  the primitive method of getting information we want to know: adding
-  "print" statements.  Metacity has a fairly structured way to do this,
-  using the functions meta_warning, meta_topic, and meta_verbose.  All
-  three have the same basic format as printf, except that meta_topic also
-  takes a leading enumeration parameter to specify the type of message
-  being shown (makes it easier for grepping in a verbose log).  You'll find
-  tons of examples in the source code if you need them; just do a quick
-  grep or look in most any file.  Note that meta_topic and meta_verbose
-  messages only appear if verbosity is turned on.  I tend to frequently add
-  temporary meta_warning statements (or switch meta_topic or meta_verbose
-  ones to meta_warning ones) and then undo the changes once I've learned
-  the info that I needed.
-
-  There is also a meta_print_backtrace (which again is only active if
-  verbosity is turned on) that can also be useful if you want to learn how
-  a particular line of code gets called.  And, of course, there's always
-  g_assert if you want to make sure some section isn't executed (or isn't
-  executed under certain conditions).
-
-  Valgrind
-
-  Valgrind is awesome for finding memory leaks or corruption and
-  uninitialized variables.  But I also tend to use it in a non-traditional
-  way as a partial substitute for a normal debugger: it can provide me with
-  a stack trace of where metacity is crashing if I made a change that
-  caused it to do so, which is one of the major uses of debuggers.  (And,
-  what makes it cooler than a debugger is that there will also often be
-  warnings pinpointing the cause of the crash from either some kind of
-  simple memory corruption or an uninitialized variable).  Sometimes, when
-  I merely want to know what is calling a particular function I'll just
-  throw in an "int i; printf("%d\n", i);" just because valgrind will give
-  me a full stacktrace whenever it sees that uninitialized variable being
-  used (yes, I could use meta_print_backtrace, but that means I have to
-  turn verbosity on).
-
-  To run metacity under valgrind, use options typical for any Gnome
-  program, such as
-    valgrind --log-file=metacity.log --tool=memcheck --num-callers=48 \
-    --leak-check=yes --leak-resolution=high --show-reachable=yes     \
-    ./src/metacity --replace
-  where, again, the backslashes mean to join all the stuff on the following
-  line with the previous one.
-
-  However, there is a downside.  Things run a little bit slowly, and it
-  appears that you'll need about 1.5GB of ram, which unfortunately prevents
-  most people from trying this.
-
-  Testing Utilities
-
-  src/run-metacity.sh
-    The script src/run-metacity.sh is useful to hack on the window manager. 
-    It runs metacity in an Xnest. e.g.:
-      CLIENTS=3 ./run-metacity.sh
-    or 
-      DEBUG=memprof ./run-metacity.sh
-    or
-      DEBUG_TEST=1 ./run-metacity-sh
-    or whatever.
-
-  metacity-message
-    The tool metacity-message can be used as follows:
-      metacity-message reload-theme
-      metacity-message restart
-      metacity-message enable-keybindings
-      metacity-message disable-keybindings
-    The first of these is useful for testing themes, the second is just
-    another way (besides the --restart flag to metacity itself) of
-    restarting metacity, and the third is useful for testing Metacity when
-    running it under an Xnest (typically, the Metacity under the Xnest
-    wouldn't get keybinding notifications--making keyboard navigation not
-    work--but if you disable the keybindings for the global Metacity then
-    the Metacity under the Xnest can then get those keybinding notifications).
-
-  metacity-window-demo
-    metacity-window-demo is good for trying behavior of various kinds
-    of window without launching a full desktop.
-
-Technical gotchas to keep in mind
-  Files that include gdk.h or gtk.h are not supposed to include
-  display.h or window.h or other core files.  Files in the core
-  (display.[hc], window.[hc]) are not supposed to include gdk.h or
-  gtk.h.  Reasons:
-
-    "Basically you don't want GDK most of the time. It adds
-    abstractions that cause problems, because they aren't designed to
-    be used in a WM where we do weird stuff (display grabs, and just
-    being the WM). At best GDK adds inefficiency, at worst it breaks
-    things in weird ways where you have to be a GDK guru to figure
-    them out. Owen also told me that they didn't want to start adding
-    a lot of hacks to GDK to let a WM use it; we both agreed back in
-    the mists of time that metacity would only use it for the "UI"
-    bits as it does.
-
-    Having the split in the source code contains and makes very clear
-    the interface between the WM and GDK/GTK. This keeps people from
-    introducing extra GDK/GTK usage when it isn't needed or
-    appropriate. Also, it speeds up the compilation a bit, though this
-    was perhaps more relevant 5 years ago than it is now.
-
-    There was also a very old worry that the GDK stuff might have to
-    be in a separate process to work right; that turned out to be
-    untrue. Though who knows what issues the CM will introduce."
-
-  Remember that strings stored in X properties are not in UTF-8, and they
-  have to end up in UTF-8 before we try putting them through Pango.
-
-  If you make any X request involving a client window, you have to
-  meta_error_trap_push() around the call; this is not necessary for X
-  requests on the frame windows.
-
-  Remember that not all windows have frames, and window->frame can be NULL.
-
-Other important reading & where to get started
-  Extra reading
-
-  There are some other important things to read to get oriented as well.
-  These are:
-    http://pobox.com/~hp/features.html
-    rationales.txt
-    doc/code-overview.txt
-
-  It pays to read http://pobox.com/~hp/features.html in order
-  to understand the philosophy of Metacity.
-
-  The rationales.txt file has two things: (1) a list of design choices with
-  links in the form of bugzilla bugs that discuss the issue, and (2) a list
-  outstanding bug categories, each of which is tracked by a particular
-  tracker bug in bugzilla from which you can find several closely related
-  bug reports.
-
-  doc/code-overview.txt provides a fairly good overview of the code,
-  including coverage of the function of the various files, the main
-  structures and their relationships, and places to start looking in the
-  code tailored to general categories of tasks.
-
-  Ideas for tasks to work on
-
-  There are a variety of things you could work on in the code.  You may
-  have ideas of your own, but in case you don't, let me provide a list of
-  ideas you could choose from:
-
-  If you're ambitious, there's a list of things Havoc made that he'd really
-  like to see tackled, which you can find at
-  http://log.ometer.com/2004-05.html.  Be sure to double check with someone
-  to make sure the item is still relevant if you're interested in one of
-  these.  Another place to look for ideas, of course, is bugzilla.  One can
-  just do queries and look for things that look fixable.
-
-  However, perhaps the best way of getting ideas of related tasks to work
-  on, is to look at the second half of the rationales.txt file, which tries
-  to group bugs by type.

-The original codebase named "Metacity" is not a meta-City as in an

-
-Since then, it has been renamed mutter after a rebase on top of

-COMPILING MUTTER
-===
-
-You need GTK+ 2.2.  For startup notification to work you need
-libstartup-notification at
-http://www.freedesktop.org/software/startup-notification/ or on the
-GNOME ftp site.
-You need Clutter 1.0. You need gobject-introspection 0.6.3.
-
-REPORTING BUGS AND SUBMITTING PATCHES
-===
-
-Report new bugs on http://bugzilla.gnome.org. Please check for
-duplicates, *especially* if you are reporting a feature request. 
-
-Please do *not* add "me too!" or "yes I really want this!" comments to
-feature requests in bugzilla. Please read
-http://pobox.com/~hp/features.html prior to adding any kind of flame
-about missing features or misfeatures.
-
-Feel free to send patches too; Metacity is relatively small and
-simple, so if you find a bug or want to add a feature it should be
-pretty easy.  Send me mail, or put the patch in bugzilla.

-See the HACKING file for some notes on hacking Mutter.
-
-MUTTER FEATURES
-===
-
- - Uses GTK+ 2.0 for drawing window frames. This means colors, fonts, 
-   etc. come from GTK+ theme.
-
- - Does not expose the concept of "window manager" to the user.  Some
-   of the features in the GNOME control panel and other parts of the
-   desktop happen to be implemented in metacity, such as changing your
-   window border theme, or changing your window navigation shortcuts,
-   but the user doesn't need to know this.
-
- - Includes only the window manager; does not try to be a desktop
-   environment. The pager, configuration, etc. are all separate and
-   modular. The "libwnck" library (which I also wrote) is available
-   for writing metacity extensions, pagers, and so on. (But libwnck
-   isn't metacity specific, or GNOME-dependent; it requires only GTK,
-   and should work with KWin, fvwm2, and other EWMH-compliant WMs.)
-
- - Has a simple theme system and a couple of extra themes come with it.
-   Change themes via gsettings:
-     gsettings set org.gnome.desktop.wm.preferences theme Crux
-     gsettings set org.gnome.desktop.wm.preferences theme Gorilla
-     gsettings set org.gnome.desktop.wm.preferences theme Atlanta
-     gsettings set org.gnome.desktop.wm.preferences theme Bright
-
-   See theme-format.txt for docs on the theme format. Use 
-   metacity-theme-viewer to preview themes.
-
- - Change number of workspaces via gsettings:
-     gsettings set org.gnome.desktop.wm.preferences num-workspaces 5
-
-   Can also change workspaces from GNOME 2 pager.
-
- - Change focus mode:
-     gsettings set org.gnome.desktop.wm.preferences focus-mode mouse
-     gsettings set org.gnome.desktop.wm.preferences focus-mode sloppy
-     gsettings set org.gnome.desktop.wm.preferences focus-mode click
-
- - Global keybinding defaults include:   
-
-    Alt-Tab                forward cycle window focus
-    Alt-Shift-Tab          backward cycle focus
-    Alt-Ctrl-Tab           forward cycle focus among panels
-    Alt-Ctrl-Shift-Tab     backward cycle focus among panels
-    Alt-Escape             cycle window focus without a popup thingy
-    Ctrl-Alt-Left Arrow    previous workspace
-    Ctrl-Alt-Right Arrow   next workspace
-    Ctrl-Alt-D             minimize/unminimize all, to show desktop
-
-   Change keybindings for example:
-
-     gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-1 '[<Alt>F1]'
-   
-   Also try the GNOME keyboard shortcuts control panel.
-
- - Window keybindings:
-
-    Alt-space         window menu
-
-    Mnemonics work in the menu. That is, Alt-space then underlined
-    letter in the menu item works.
-
-    Choose Move from menu, and arrow keys to move the window.
-
-    While moving, hold down Control to move slower, and 
-      Shift to snap to edges.
-
-    Choose Resize from menu, and nothing happens yet, but 
-      eventually I might implement something.
-
-    Keybindings for things like maximize window, vertical maximize,
-    etc. can be bound, but may not all exist by default. See
-    metacity.schemas.
-
- - Window mouse bindings:
-
-    Clicking anywhere on frame with button 1 will raise/focus window
-    
-    If you click a window control, such as the close button, then the 
-     control will activate on button release if you are still over it
-     on release (as with most GUI toolkits)
-
-    If you click and drag borders with button 1 it resizes the window
-    
-    If you click and drag the titlebar with button 1 it moves the 
-     window.
-
-    If you click anywhere on the frame with button 2 it lowers the 
-     window.
-
-    If you click anywhere on the frame with button 3 it shows the 
-     window menu.
-
-    If you hold down Super (windows key) and click inside a window, it
-     will move the window (buttons 1 and 2) or show menu (button 3).
-     Or you can configure a different modifier for this.
-
-    If you pick up a window with button 1 and then switch workspaces
-     the window will come with you to the new workspace, this is 
-     a feature copied from Enlightenment.
-
-    If you hold down Shift while moving a window, the window snaps
-     to edges of other windows and the screen.
-
- - Session management:
-
-    Mutter connects to the session manager and will set itself up to
-     be respawned. It theoretically restores sizes/positions/workspace
-     for session-aware applications.
-
- - Mutter implements much of the EWMH window manager specification
-   from freedesktop.org, as well as the older ICCCM.  Please refer to
-   the COMPLIANCE file for information on mutter compliance with
-   these standards.
-
- - Uses Pango to render text, so has cool i18n capabilities. 
-   Supports UTF-8 window titles and such.
-
- - There are simple animations for actions such as minimization, 
-   to help users see what is happening. Should probably 
-   have a few more of these and make them nicer.
-
- - if you have the proper X setup, set the GDK_USE_XFT=1 
-   environment variable to get antialiased window titles.
-
- - considers the panel when placing windows and maximizing
-   them.
-
- - handles the window manager selection from the ICCCM. Will exit if
-   another WM claims it, and can claim it from another WM if you pass
-   the --replace argument. So if you're running another
-   ICCCM-compliant WM, you can run "mutter --replace" to replace it
-   with Metacity.
-
- - does basic colormap handling
-
- - and much more! well, maybe not a lot more.
-
-HOW TO ADD EXTERNAL FEATURES
-===
-
-You can write a mutter "plugin" such as a pager, window list, icon
-box, task menu, or even things like "window matching" using the
-Extended Window Manager Hints. See http://www.freedesktop.org for the
-EWMH specification. An easy-to-use library called "libwnck" is
-available that uses the EWMH and is specifically designed for writing
-WM accessories.
-
-You might be interested in existing accessories such as "Devil's Pie"
-by Ross Burton, which add features to Mutter (or other
-EWMH-compliant WMs).

-MUTTER BUGS, NON-FEATURES, AND CAVEATS

-
-See bugzilla: http://bugzilla.gnome.org/query.cgi
-
-FAQ
-===
-
-Q: Will you add my feature?
-
-A: If it makes sense to turn on unconditionally, or is genuinely a
-   harmless preference that I would not be embarrassed to put in a
-   simple, uncluttered, user-friendly configuration dialog.
-
-   If the only rationale for your feature is that other window
-   managers have it, or that you are personally used to it, or
-   something like that, then I will not be impressed. Metacity is
-   firmly in the "choose good defaults" camp rather than the "offer 6
-   equally broken ways to do it, and let the user pick one" camp.
-
-   This is part of a "no crackrock" policy, despite some exceptions
-   I'm mildly embarrassed about. For example, multiple workspaces
-   probably constitute crackrock, they confuse most users and really
-   are not that useful if you have a decent tasklist and so on. But I
-   am too used to them to turn them off.  Or alternatively
-   iconification/tasklist is crack, and workspaces/pager are good. But
-   having both is certainly a bit wrong.  Sloppy focus is probably
-   crackrock too.
-
-   But don't think unlimited crack is OK just because I slipped up a
-   little. No slippery slope here.
-
-   Don't let this discourage patches and fixes - I love those. ;-)
-   Just be prepared to hear the above objections if your patch adds
-   some crack-ridden configuration option.
-
-   http://pobox.com/~hp/free-software-ui.html
-   http://pobox.com/~hp/features.html   
-
-Q: Will Mutter be part of GNOME?
-
-A: It is not officially part of GNOME as of GNOME 2.27. We are
-   hoping to have mutter officially included as of GNOME 2.28. 
-
-Q: Why does Mutter remember the workspace/position of some apps 
-   but not others across logout/login?
-
-A: Mutter only stores sizes/positions for apps that are session
-   managed. As far as I can determine, there is no way to attempt to
-   remember workspace/position for non-session-aware apps without
-   causing a lot of weird effects.
-
-   The reason is that you don't know which non-SM-aware apps were
-   launched by the session. When you initially log in, Metacity sees a
-   bunch of new windows appear. But it can't distinguish between
-   windows that were stored in your session, or windows you just
-   launched after logging in. If Metacity tried to guess that a window
-   was from the session, it could e.g. end up maximizing a dialog, or
-   put a window you just launched on another desktop or in a weird
-   place. And in fact I see a lot of bugs like this in window managers
-   that try to handle non-session-aware apps.
-
-   However, for session-aware apps, Mutter can tell that the
-   application instance is from the session and thus restore it
-   reliably, assuming the app properly restores the windows it had 
-   open on session save.
-   
-   So the correct way to fix the situation is to make apps
-   session-aware. libSM has come with X for years, it's very
-   standardized, it's shared by GNOME and KDE - even twm is
-   session-aware. So anyone who won't take a patch to add SM is more
-   archaic than twm - and you should flame them. ;-)
-
-   Docs on session management:
-    http://www.fifi.org/doc/xspecs/xsmp.txt.gz
-    http://www.fifi.org/doc/xspecs/SMlib.txt.gz
-
-   See also the ICCCM section on SM. For GNOME apps, use the
-   GnomeClient object. For a simple example of using libSM directly,
-   twm/session.c in the twm source code is pretty easy to understand.
-
-Q: How about adding viewports in addition to workspaces?
-
-A: I could conceivably be convinced to use viewports _instead_ of
-   workspaces, though currently I'm not thinking that. But I don't
-   think it makes any sense to have both; it's just confusing. They
-   are functionally equivalent.
-
-   You may think this means that you won't have certain keybindings, 
-   or something like that. This is a misconception. The only 
-   _fundamental_ difference between viewports and workspaces is that 
-   with viewports, windows can "overlap" and appear partially on 
-   one and partially on another. All other differences that
-   traditionally exist in other window managers are accidental - 
-   the features commonly associated with viewports can be implemented
-   for workspaces, and vice versa.
-
-   So I don't want to have two kinds of
-   workspace/desktop/viewport/whatever, but I'm willing to add
-   features traditionally associated with either kind if those
-   features make sense.
-
-Q: Why is the panel always on top?
-
-A: Because it's a better user interface, and until we made this not
-   configurable a bunch of apps were not getting fixed (the app
-   authors were just saying "put your panel on the bottom" instead of
-   properly supporting fullscreen mode, and such).
-
-   rationales.txt has the bugzilla URL for some flamefesting on this,
-   if you want to go back and relive the glory.
-   Read these and the bugzilla stuff before asking/commenting:
-     http://pobox.com/~hp/free-software-ui.html
-     http://pobox.com/~hp/features.html   
-
-Q: Why is there no edge flipping?
-
-A: This one is also in rationales.txt. Because "ouija board" UI, where
-   you just move the mouse around and the computer guesses what you
-   mean, has a lot of issues. This includes mouse focus, shade-hover
-   mode, edge flipping, autoraise, etc. Metacity has mouse focus and
-   autoraise as a compromise, but these features are all confusing for
-   many users, and cause problems with accessibility, fitt's law, and
-   so on.
-
-   Read these and the bugzilla stuff before asking/commenting:
-     http://pobox.com/~hp/free-software-ui.html
-     http://pobox.com/~hp/features.html   
-
-Q: Why does wireframe move/resize suck?
-
-A: You can turn it on with the reduced_resources setting.
-
-   But: it has low usability, and is a pain
-   to implement, and there's no reason opaque move/resize should be a
-   problem on any setup that can run a modern desktop worth a darn to
-   begin with.
-
-   Read these and the bugzilla stuff before asking/commenting:
-     http://pobox.com/~hp/free-software-ui.html
-     http://pobox.com/~hp/features.html   
-
-   The reason we had to add wireframe anyway was broken 
-   proprietary apps that can't handle lots of resize events.
-
-Q: Why no XYZ?
-
-A: You are probably getting the idea by now - check rationales.txt,
-   query/search bugzilla, and read http://pobox.com/~hp/features.html
-   and http://pobox.com/~hp/free-software-ui.html
-
-   Then sit down and answer the question for yourself.  Is the feature
-   good? What's the rationale for it? Answer "why" not just "why not."
-   Justify in terms of users as a whole, not just users like
-   yourself. How else can you solve the same problem? etc. If that
-   leads you to a strong opinion, then please, post the rationale for
-   discussion to an appropriate bugzilla bug, or to
-   usability@gnome.org.
-
-   Please don't just "me too!" on bugzilla bugs, please don't think
-   flames will get you anywhere, and please don't repeat rationale
-   that's already been offered.
-
-Q: Your dumb web pages you made me read talk about solving problems in
-   fundamental ways instead of adding preferences or workarounds.
-   What are some examples where metacity has done this?
-
-A: There are quite a few, though many opportunities remain.  Sometimes
-   the real fix involves application changes. The metacity approach is
-   that it's OK to require apps to change, though there are also
-   plenty of workarounds in metacity for battles considered too hard
-   to fight.
-
-   Here are some examples:
-
-   - fullscreen mode was introduced to allow position constraints,
-     panel-on-top, and other such things to apply to normal windows
-     while still allowing video players etc. to "just work"
-
-   - "whether to include minimized windows in Alt+Tab" was solved 
-     by putting minimized windows at the *end* of the tab order. 
-
-   - Whether to pop up a feedback display during Alt+Tab was solved by
-     having both Alt+Tab and Alt+Esc
-
-   - Whether to have a "kill" feature was solved by automatically
-     detecting and offering to kill stuck apps. Better, metacity
-     actually does "kill -9" on the process, it doesn't just
-     disconnect the process from the X server. You'll appreciate this
-     if you ever did a "kill" on Netscape 4, and watched it keep
-     eating 100% CPU even though the X server had booted it.
-
-   - The workspaces vs. viewports mess was avoided by adding
-     directional navigation and such to workspaces, see discussion
-     earlier in this file.
-
-   - Instead of configurable placement algorithms, there's just one 
-     that works fairly well most of the time.
-
-   - To avoid excess CPU use during opaque move/resize, we rate limit
-     the updates to the application window's size.
-
-   - Instead of configurable "show size of window while resizing,"
-     it's only shown for windows where it matters, such as terminals.
-     (Only use-case given for all windows is for web designers
-     choosing their web browser size, but there are web sites and
-     desktop backgrounds that do this for you.)
-
-   - Using startup notification, applications open on the workspace
-     where you launched them, not the active workspace when their
-     window is opened.
-
-   - and much more.
-
-Q: I think mutter sucks.
-
-A: Feel free to use any WM you like. The reason metacity follows the
-   ICCCM and EWMH specifications is that it makes metacity a modular,
-   interchangeable part in the desktop. libwnck-based apps such as the
-   GNOME window list will work just fine with any EWMH-compliant WM.
-
-Q: Did you spend a lot of time on this?
-
-A: Originally the answer was no. Sadly the answer is now yes.
-
-Q: How can you claim that you are anti-crack, while still 
-   writing a window manager?
-
-A: I have no comment on that.

-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.
