+Metacity Standards Compliance
+=============================
+$Id$
+
+1) Introduction
+2) EWMH Compliance
+  a. Root Window Properties
+  b. Root Window Messages
+  c. Application Window Properties
+  d. Window Manager Protocols
+3) ICCCM Compliance
+
+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.
+
+  d. Window Manager Protocols

+Intro...
+
+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.
+

+  Minimal Building/Testing Environment
+  Relevant standards and X properties
+  Debugging and testing
+    Debugging logs

+    Valgrind
+    Testing Utilities

+
+
+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.

README

@@ -0,0 +1,416 @@
+The original codebase named "Metacity" is not a meta-City as in an
+urban center, but rather Meta-ness as in the state of being
+meta. i.e. metacity : meta as opacity : opaque. Also it may have
+something to do with the Meta key on UNIX keyboards.
+
+Since then, it has been renamed mutter after a rebase on top of
+clutter as a compositing manager.
+
+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/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.

- * The overall model drawing model of this widget is that we have one
- * texture, or two interpolated textures, possibly with alpha or
- * margins that let the underlying background show through, blended
- * over a solid color or a gradient. The result of that combination
- * can then be affected by a "vignette" that darkens the background
- * away from a central point (or as a no-GLSL fallback, simply darkens
- * the background) and by overall opacity.
- *
- * As of GNOME 3.14, GNOME is only using a fraction of this when the
- * user sets the background through the control center - what can be
- * set is:
- *
- *  A single image without a border
- *  An animation of images without a border that blend together,
- *   with the blend changing every 4-5 minutes
- *  A solid color with a repeated noise texture blended over it
- *
- * This all is pretty easy to do in a fragment shader, except when:
- *
- *  A) We don't have GLSL - in this case, the operation of
- *     interpolating the two textures and blending the result over the
- *     background can't be expressed with Cogl's fixed-function layer
- *     combining (which is confined to what GL's texture environment
- *     combining can do) So we can only handle the above directly if
- *     there are no margins or alpha.
- *
- *  B) The image textures are sliced. Texture size limits on older
- *     hardware (pre-965 intel hardware, r300, etc.)  is often 2048,
- *     and it would be common to use a texture larger than this for a
- *     background and expect it to be scaled down. Cogl can compensate
- *     for this by breaking the texture up into multiple textures, but
- *     can't multitexture with sliced textures. So we can only handle
- *     the above if there's a single texture.
- *
- * However, even when we *can* represent everything in a single pass,
- * it's not necessarily efficient. If we want to draw a 1024x768
- * background, it's pretty inefficient to bilinearly texture from
- * two 2560x1440 images and mix that. So the drawing model we take
- * here is that MetaBackground generates a single texture (which
- * might be a 1x1 texture for a solid color, or a 1x2 texture for a
- * gradient, or a repeated texture for wallpaper, or a pre-rendered
- * texture the size of the screen), and we draw with that, possibly
- * adding the vignette and opacity.
