+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...
 
-Don't commit substantive code in here without asking me,
-hp@redhat.com.  Adding translations, no-brainer typo fixes, etc.  is
-fine.
+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.
 
-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 whatever.
-
-src/window.c is where all the guts of the window manager live. This is
-basically the only remotely scary file.
-
-src/frames.c is the GtkWidget that handles drawing window frames.
-
-src/core.h defines the interface used by the GTK portion of the window
-manager to talk to the other portions. There's some cruft in here
-that's unused, since nearly all window operations have moved out of
-this file so frameless apps can have window operations.
-
-src/ui.h defines the interface the plain Xlib portion of the window
-manager uses to talk to the GTK portion.
-
-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.
-
-When hacking, remember that you can have multiple screens. The code is
-also written to support multiple displays, but this is useless, since
-you can just run two copies of the WM. Also, an XKillClient() or
-shutdown on any display causes Xlib to exit the app, so it would be
-broken. So the multi-display thing is mostly just for code
-cleanliness.  Multi-screen on the other hand is important for some
-people.
-
-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.
-
-The code could use cleanup in a lot of places, feel free to do so.

+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.
+
+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 --logfile=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
+
+  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.
+
+  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.

+2.13.2
+==
+
+This release just contains a merge of all the changes on the
+constraints_experiments branch.
+
+Thanks to Havoc Pennington for reviewing the gargantuan patch and
+suggesting lots of little fixes for making it better, to Rob Adams and
+Soeren Sandmann for grilling me on how some of the difficult internals work
+-- allowing me to improve the documentation, to Olav Vitters for finding an
+easy-to-fix crasher bug in early testing and for repeatedly extending my
+deadline for switching from working on Metacity to Bugzilla, to Ray Strode
+for finding two crashers and fixing one of them in early testing, to Bryan
+Clark for usability advice, to Davyd Madeley and Christian Kellner for
+testing Xinerama stuff, to Sebastien Bacher for packaging an early version
+and finding some obscure bugs (that I unfortunately still can't duplicate
+and will probably still need to fix once I can),
+
+Bugs fixed:
+  unfiled - constraints.c is overly complicated[1]
+  unfiled - constraints.c is not robust when all constraints cannot
+            simultaneously be met (constraints need to be prioritized)
+  unfiled - keep-titlebar-onscreen constraint is decoration unaware (since
+            get_outermost_onscreen_positions() forgets to include
+            decorations)
+  unfiled - keyboard snap-moving and snap-resizing snap to hidden edges
+   109553 - gravity w/ simultaneous move & resize doesn't work
+   113601 - maximize vertical and horizontal should toggle and be
+            constrained
+   122196 - windows show up under vertical panels
+   122670 - jerky/random resizing of window via keyboard[2]
+   124582 - keyboard and mouse snap-resizing and snap-moving erroneously
+            moves the window multidimensionally
+   136307 - don't allow apps to resize themselves off the screen (*cough*
+            filechooser *cough*)
+   142016, 143784 - windows should not span multiple xineramas unless
+            placed there by the user
+   143145 - clamp new windows to screensize and force them onscreen, if
+            they'll fit
+   144126 - Handle pathological strut lists sanely[3]
+   149867 - fixed aspect ratio windows are difficult to resize[4]
+   152898 - make screen edges consistent; allow easy slamming of windows
+            into the left, right, and bottom edges of the screen too.
+   154706 - bouncing weirdness at screen edge with keyboard moving or
+            resizing
+   156699 - avoid struts when placing windows, if possible (nasty a11y
+            blocker)
+   302456 - dragging offscreen too restrictive
+   304857 - wireframe moving off the top of the screen is misleading
+   308521 - make uni-directional resizing easier with alt-middle-drag and
+            prevent the occasional super annoying resize-the-wrong-side(s)
+            behavior
+   312007 - snap-resize moves windows with a minimum size constraint
+   312104 - resizing the top of a window can cause the bottom to grow
+   319351 - don't instantly snap on mouse-move-snapping, remove
+            braindeadedness of having order of releasing shift and
+            releasing button press matter so much
+
+   [1] fixed in my opinion, anyway.
+   [2] Actually, it's not totally fixed--it's just annoying
+       instead of almost completely unusable.  Matthias had a
+       suggestion that may fix the remainder of the problems (see
+       http://tinyurl.com/bwzuu).
+   [3] This bug was originally about not-quite-so-pathological
+       cases but was left open for the worse cases. The code from
+       the branch handles the remainder of the cases mentioned in
+       this bug.
+   [4] Actually, although it's far better there's still some minor
+       issues left: a slight drift that's only noticeable after
+       lots of resizing, and potential problems with partially
+       onscreen constraints due to not clearing any
+       fixed_directions flags (aspect ratio windows get resized in
+       both directions and thus aren't fixed in one of them)
+        
+New feature:
+  81704 - edge resistance for user move and resize operations; in
+          particular 3 different kinds of resistance are implemented:
+     Pixel-Distance: window movement is resisted when it aligns with an
+       edge unless the movement is greater than a threshold number of
+       pixels
+     Timeout: window movement past an edge is prevented until a certain
+       amount of time has elapsed during the operation since the first
+       request to move it past that edge
+     Keyboard-Buildup: when moving or resizing with the keyboard, once a
+       window is aligned with a certain edge it cannot move past until the
+       correct direction has been pressed enough times (e.g. 2 or 3 times)
+
+Major code changes:
+  - constraints.c has been rewritten; very few lines of code from the old
+    version remain.  There is a comment near the top of the function
+    explaining the basics of how the new framework works.  A more detailed
+    explanation can be found in doc/how-constraints-works.txt
+  - edge-resistance.[ch] are new files implementing edge-resistance.
+  - boxes.[ch] are new files containing low-level error-prone functions
+    used heavily in constraints.c and edge-resistance.c, among various
+    places throughout the code.  testboxes.c contains a thorough testsuite
+    for the boxes.[ch] functions compiled into a program, testboxes.
+  - meta_window_move_resize_internal() *must* be told the gravity of the
+    associated operation (if it's just a move operation, the gravity will

+Many bugfixes and better support for the freedesktop.org EWMH spec.
+
+Thanks to Rob Adams, Anders Carlsson, Elijah Newren, Soeren Sandmann,
+Emil Soleyman-Zomalan, Michael Terry, and Jeff Waugh for fixes in this
+release.
+
+  - set titlebar_uses_system_font = false (it was ugly)
+  - make naming for "move a window"/"move the window"/"move window"
+    more consistent (fixes #142235)
+  - Add trailing quotes to keybinding explanation text.
+  - support for EWMH update counter spec & add compensation events
+    when events are ignored. (fixes #143333 and #109362)
+  - Fix focus bugs: remove race condition on window close/minimize
+    (#131582), make focus choice consistent for each focus mode
+    (#135810), choose correct focus window when "un-showing the
+    desktop (#144900), make sure correct window is focused when using
+    the workspace switcher (#120100).
+  - Use meta_topic instead of meta_warning when failing to connect to
+    a session manager; reduces metacity verbosity. (fixes #136218)
+  - Make meta_window_delete take a timestamp, and be sure to pass it
+    one.
+  - Add support for EWMH _NET_WM_USER_TIME spec.  This enables part of
+    preventing focus stealing.  (bug #118372) Also fix bug with
+    windows not being focused on unminimizing caused by original
+    patch.  (also bug #118372)
+  - Fix some support for EWMH hints, and fix USER_TIME support to
+    include the DEMANDS_ATTENTION hint.  Also includes some code for
+    implementing _NET_RESTACK_WINDOW and _NET_MOVERESIZE_WINDOW, but
+    this is disabled pending feature thaw.

 COMPILING METACITY
 ===
 
-You need GTK+ 1.3.x (to become 2.0), at least version 1.3.7.  At the
-moment CVS HEAD works, but that can change. Metacity is a fairly
-trivial 6000-line C program, so once you get GTK+ built it should be
-no problem to build Metacity.
-
-There are SRPMs on the ftp site (there were also binaries for a bit,
-but I am taking them down because they only worked with Rawhide, so it
-was sort of pointless). Just "rpm --rebuild metacity-whatever.src.rpm"
-after installing the GTK packages from ftp.gtk.org.
+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 also need GConf 1.2 (unless building a funky
+extra-small embedded metacity with --disable-gconf, see below).
 
 REPORTING BUGS AND SUBMITTING PATCHES

-Report new bugs to hp@redhat.com for now. Will switch to Bugzilla
-sometime probably.
+Report new bugs on http://bugzilla.gnome.org. Please check for
+duplicates, *especially* if you are reporting a feature request. 
 
-Feel free to send patches too; Metacity is really small and simple, so

+Please do *not* add "me too!" or "yes I really want this!" comments to

+SHRINKING METACITY
+===
+
+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.

 METACITY FEATURES

@@ -39,18 +79,62 @@ METACITY FEATURES
  - Uses GTK+ 2.0 for drawing window frames. This means colors, fonts, 
    etc. come from GTK+ theme.
 
- - There are 6 workspaces.
+ - 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.
 
- - Global keybindings:
-    Alt-F1 to Alt-F6  switch workspaces
-    Alt-1  to Alt-6   switch workspaces
-    Alt-Tab           forward cycle window focus
-    Alt-Shift-Tab     backward cycle focus
-    Alt-Escape        focus previous window
-    Alt-Left Arrow    previous workspace
-    Alt-Right Arrow   next workspace
+ - 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 gconf-editor or gconftool or GNOME themes control
+   panel:
+     gconftool-2 --type=string --set /apps/metacity/general/theme Crux
+     gconftool-2 --type=string --set /apps/metacity/general/theme Gorilla
+     gconftool-2 --type=string --set /apps/metacity/general/theme Atlanta
+     gconftool-2 --type=string --set /apps/metacity/general/theme Bright
+
+   See theme-format.txt for docs on the theme format. Use 
+   metacity-theme-viewer to preview themes.
+
+ - Change number of workspaces via gconf-editor or gconftool:
+     gconftool-2 --type=int --set /apps/metacity/general/num_workspaces 5
+
+   Can also change workspaces from GNOME 2 pager.
+
+ - Change focus mode:
+     gconftool-2 --type=string --set /apps/metacity/general/focus_mode mouse
+     gconftool-2 --type=string --set /apps/metacity/general/focus_mode sloppy
+     gconftool-2 --type=string --set /apps/metacity/general/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

+

+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 Metacity (or other
+EWMH-compliant WMs).

 METACITY BUGS, NON-FEATURES, AND CAVEATS
 ===
 
- - Metacity creates a big file in your home directory called
-   ~/metacity.log with a bunch of debug spew.
-
- - If you want a number of workspaces which is not 6, you have to 
-   edit screen.c and recompile.
-
- - If you want keybindings which are not the ones mentioned above
-   as features, you have to edit keybindings.c and recompile.
-
- - Metacity does not have any way to unminimize a window. So 
-   clicking the minimize button is sort of a bad idea.
-   (If you had a WM-spec-compliant tasklist, it would work
-   for unminimization.)
-
- - Metacity uses the new window manager spec, but only random bits of
-   the old GNOME spec. It correctly advertises exactly which parts of
-   the GNOME spec it supports, but it does not support enough of it to
-   make the GNOME task list and desk guide happy, and they do not
-   support the new spec. I don't want anyone to spend time sending me
-   patches to support the old GNOME spec in Metacity; instead, send
-   patches to the task list and desk guide to support the new spec. As
-   far as I know, Metacity does support enough of the new spec to
-   allow a working tasklist and pager.
-
-   Upshot: task list and desk guide DO NOT WORK with Metacity.
-
- - Metacity turns off its keybindings for Emacs, because I use 
-   Alt-space in Emacs, and getting a window menu annoys me.
-   This is a broken feature. My planned fix is to use super/hyper 
-   instead of Alt as the main keybinding shortcut, if super/hyper 
-   exist, and then keyboards with a windows key can use that for 
-   WM functions and Alt for application shortcuts.
-   We'd fall back to Alt if no other suitable modifier existed.
-   
- - Cycling windows with Alt-Tab is flickery, AFAIK because
-   Metacity passes the entire window stack to XRestackWindows() 
-   every time you restack. Instead it should probably only restack 
-   windows that have changed their stacking with respect to one 
-   another. (But sometimes I don't see the flicker, so 
-   I'm not sure.)
-
- - I haven't even read the ICCCM section about colormaps. So if you 
-   have an 8-bit display you are basically screwed.
-
- - Metacity doesn't properly claim the window manager selection
-   as described in the ICCCM. But then, most other window managers
-   don't handle this correctly either.
-
- - There are probably other ICCCM-compliance issues.
-
- - Window placement is always cascade for now; I want to implement 
-   "first fit, falling back to cascade if no fit." 
-   (Configurable placement algorithms are stupid though, don't 
-   send me patches for any bogus ones. Let's just pick a good one.)
-
- - Maximization and movement constraints do not take the 
-   GNOME panel into account. Most of the code already handles
-   this (using workspace->workarea in workspace.h), but 
-   workspace->workarea isn't ever actually calculated.
-   Metacity needs to keep this area up-to-date using the hints the
-   panel sets.
-
- - Should support click-to-focus as an option.
-
- - Should Metacity support flipping in right-to-left locales?
-   I don't know what window managers look like in a right-to-left
-   locale. I assume the window titles should be right-justified;
-   should the window controls also be flipped?
-
- - Need keyboard shortcuts for hide/show desktop (minimize/unminimize
-   all windows temporarily, basically, and focus desktop); also 
-   for focusing dock windows (though since current GNOME panel has 
-   no useful keynav, this doesn't get you far at the moment).
-
- - Resize menu item doesn't do anything. It's intended to enter
-   resize-with-the-keyboard mode, similar to Move menu item.
-
- - I haven't set up the po subdir and translations, mostly because
-   autotools seem to get all confused if you set these up but 
-   don't actually have any translations. So if someone translates
-   something we can set it up.
-
- - If you switch from sawfish to metacity without restarting X, 
-   the panel often ends up buried behind the Nautilus desktop window.
-
-   What happens is that the panel detects Sawfish has gone away, and
-   turns on override redirect mode because no GNOME-aware WM is
-   running (i.e. it goes into "ignore the window manager" mode). But
-   the panel doesn't notice that Metacity has appeared and is
-   (partially) GNOME-compliant. So Metacity doesn't see the override
-   redirect panel, and leaves it behind the Nautilus desktop. I'm not
-   sure whether Metacity or the panel is to blame for this.
-
-   (To debug - use "xwininfo" on the panel, if override redirect is
-    "Yes" then Metacity won't have any awareness of a window and can't
-    properly stack it above the desktop. If override redirect is "No"
-    then Metacity can see the panel and handle it properly. Look at
-    xstuff.c:xstuff_is_compliant_wm() in the panel to get started on
-    how the panel deals with this.)
-
- - If you have "put panel below other windows" turned on 
-   in panel Global Preferences, Miscellaneous tab, you need to change  
-   this to "Put panel on top of other windows." That's because
-   Metacity uses semantic categories, not the legacy layer system 
-   in the GNOME spec. It treats things in the legacy "dock" layer
-   as semantic type dock, but if you have the panel set to be 
-   in another layer, Metacity will think it's a normal window.
-
-   You can diagnose this problem because Metacity will put panels in 
-   the wrong place, and Alt+rightclick will let you perform operations
-   like minimize/maximize, and Alt+leftclick will let you move the panel.
-   If Metacity has detected that the panel is a panel, then none of 
-   this will be enabled.
-
-   I put a patch in the CVS version of the panel to fix this by 
-   setting the new non-legacy type hint, but a panel with that 
-   patch hasn't been released yet.

    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. Oh, and my Alt-1 thru Alt-6
-   keybindings are definitely on crack.

 Q: Will Metacity be part of GNOME?
 
-A: This is not the current plan, though of course I'm happy to see the

-   For now Metacity is my toy hobby project that I work on when I feel
-   like it.
+A: It is officially part of GNOME as of GNOME 2.2. Prior to that, 
+   it was unofficially shipped as the default GNOME WM by several 
+   OS vendors.
 
 Q: Is Metacity a Red Hat project?
 
-A: Metacity is in no way funded, endorsed, or encouraged by Red Hat,

-Q: Why can't I move XMMS?
-
-A: Because XMMS is broken and is trying to move itself. Metacity

@@ -361,17 +329,144 @@ A: I could conceivably be convinced to use viewports _instead_ of
    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).

+
+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

+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

+     http://pobox.com/~hp/free-software-ui.html

+
+   The reason we had to add wireframe anyway was broken

+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 metacity 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: Metacity is about 6000 lines of code, which took a few weekends and
-   evenings to write. If it ever becomes more polished it will
-   probably grow 2-3 more thousand lines of code and suck a few more
-   weekends of time. If I started adding all kinds of features and 
-   crack-ridden configuration options, it might take more time than that. 
+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.

+  src/window.c is where all the guts of the window manager live. This is
+  basically the only remotely scary file.
+
+  src/frames.c is the GtkWidget that handles drawing window frames.
+
+  src/core.h defines the interface used by the GTK portion of the window
+  manager to talk to the other portions. There's some cruft in here that's
+  unused, since nearly all window operations have moved out of this file so
+  frameless apps can have window operations.
+
+  src/ui.h defines the interface the plain Xlib portion of the window
+  manager uses to talk to the GTK portion.
+
+  src/theme.c and src/theme-parser.c have the theme system; this is
+  well-modularized from the rest of the code, since the theme viewer app
+  links to these files in addition to the WM itself.
+
+Major data structures and their relationships
+  Major structs have a "Meta" prefix, thus MetaDisplay, MetaScreen,
+  MetaWindow, etc.  This serves as a way of namespacing in C.  It also has
+  the side effect of avoiding conflicts with common names that X already
+  uses such as Display, Screen, Window, etc.  Note that when I refer to a
+  display below, I'm meaning a MetaDisplay and not a Display.
+
+  Don't confuse displays and screens.  While Metacity can run with multiple
+  displays, it is kind of useless since you might as well just run two
+  copies of Metacity.  However, having multiple screens per display is
+  useful and increasingly common (known as "multiscreen" and "xinerama"
+  setups, where users make use of more than one monitor).  You should
+  basically think of a display as a combination of one or more monitors
+  with a single keyboard (...and usually only one mouse).
+
+  There is also a significant difference between multiscreen and xinerama
+  as well.  Basically, each MetaScreen is a root window (root node in the
+  tree of windows).  With Xinerama, a single root window appears to span
+  multiple monitors, whereas with multiscreen a root window is confined to
+  a single monitor.  To re-emphasize the distinction between a display and
+  a screen, the pointer and keyboard are shared between all root windows
+  for a given display.
+
+  The display keeps track of a lot of various global quantities, but in
+  particular has a compositor and a list (GList) of screens.
+
+  A compositor is an opaque structure (only defined in compositor.c),
+  meaning that you'll only reference the API for it.  It handles (or will
+  handle) cool stuff with the new X extensions, such as smooth resizing and
+  alpha transparency.
+
+  A screen keeps track of a number of quantities as well, in particular a
+  stack and a list of workspaces.
+
+  A stack is basically a list of windows, and the depth order they have
+  relative to each other (which thus determines which windows are on top
+  and which are obscured).
+
+  A workspace mostly contains a list of windows for the workspace, but also
+  has a few other quantities as well (a list of struts which are areas
+  where windows should not be placed and an mru_list or "most recently used
+  window list").
+
+  A window has a huge list of quantities for keeping track of things about
+  a window on the screen.  (We want to avoid making this list larger
+  because the memory for all these quantities is per window.)  One item in
+  particular that a window has, though, is a frame.
+
+  A frame is the decorations that surround the window (i.e. the titlebar and
+  the minimize and close buttons and the part that you can use to resize),
+  and contains a handful of variables related to that, but no other major
+  structures.
+
+Getting started -- where to look
+  Getting started on developing free software projects can often be like
+  being dropped off in a town that is unknown to you and being told to make
+  a map, when various road and building signs are missing or fading.  To
+  try to alleviate that initial difficulty in orientation, below I list a
+  variety of general task categories with file, function, variable, and x
+  property names that may be useful to fixing bugs or writing features that
+  fall within that category.
+
+  First, though, it's useful to note that most event and message passing
+  goes through display.c:event_callback(), so that's often a good place to
+  start reading for general familiarity with the code (actually, I'd
+  suggest skipping down to the first switch statement within that
+  function).  Of course, not all events go through that function, as there
+  are a few other places that handle events too such as frames.c.
+
+  Anyway, without further ado, here are the categories and (hopefully)
+  useful things to look at for each:

+        http://freedesktop.org/Standards/XDND)
+      _NET_WM_MOUSE_ACTION/_NET_WM_TAKE_ACTIVITY (aren't yet in EWMH)
+      A general pointer: what causes the difficulty here is that when the
+        application receives a mouse click to start a drag, it does a grab
+        so that the window manager doesn't get any further events; thus

+  Basic Ideas
+  Important points to remember
+  Explanation of fields in the ConstraintInfo struct
+  Gory details of resize_gravity vs. fixed_directions
+
+IMPORTANT NOTE: There's a big comment at the top of constraints.c
+explaining how to add extra constraints or tweak others.  Read it.  I put
+that information there because it may be enough information by itself for
+people to hack on constraints.c.  I won't duplicate that information in
+this file; this file is for deeper details.
+
+
+---------------------------------------------------------------------------
+Basic Ideas
+---------------------------------------------------------------------------
+There are a couple basic ideas behind how this constraints.c code works and
+why it works that way:
+
+  1) Split the low-level error-prone operations into a special file
+  2) Add robustness by prioritizing constraints
+  3) Make use of a minimal spanning set of rectangles for the
+     "onscreen region" (screen minus struts).
+  4) Constraints can be user-action vs app-action oriented
+  5) Avoid over-complification  ;-)
+
+Some more details explaining these basic ideas:
+
+  1) Split tedious operations out
+
+     boxes.[ch] have been added which contain many common, tedious, and
+     error-prone operations.  I find that this separation helps a lot for
+     managing the complexity and ensuring that things work correctly.
+     Also, note that testboxes.c thoroughly tests all functionality in
+     boxes.[ch] and a testboxes program is automatically compiled.
+
+     Note that functions have also been added to this file to handle some
+     of the tedium necessary for edge resistance as well.
+
+  2) Prioritize constraints
+
+     In the old code, if each and every constraint could not be
+     simultaneously satisfied, then it would result in some
+     difficult-to-predict set of constraints being violated.  This was
+     because constraints were applied in order, with the possibility for
+     each making changes that violated previous constraints, with no
+     checking done at the end.
+
+     Now, all constraints have an associated priority, defined in the
+     ConstraintPriority enum near the top of constraints.c.  The
+     constraints are all applied, and then are all checked; if not all are
+     satisfied then the least important constraints are dropped and the
+     process is repeated.  This ensures that the most important constraints
+     are satisfied.
+
+     A special note to make here is that if any one given constraint is
+     impossible to satisfy even individually (e.g. if minimum size hints
+     specify a larger window than the screen size, making the
+     fully-onscreen constraint impossible to satisfy) then we treat the
+     constraint as being satisfied.  This sounds counter-intuitive, but the
+     idea is that we want to satisfy as many constraints as possible and if
+     we treat it as a violation then all constraints with a lesser priority
+     also get dropped along with the impossible to satisfy one.
+
+  3) Using maximal/spanning rectangles
+
+     The constraints rely heavily on something I call spanning rectangles
+     (which Soeren referred to as maximal rectangles, a name which I think
+     I like better but I don't want to go change all the code now).  These
+     spanning rectangles have the property that a window will fit on the
+     screen if and only if it fits within at least one of the rectangles.
+     Soeren had an alternative way of describing these rectangles, namely
+     that they were rectangles with the property that if you made any of
+     them larger in any direction, they would overlap with struts or be
+     offscreen (with the implicit assumption that there are enough of these
+     rectangles that combined they cover all relevant parts of the screen).
+     Note that, by necessity, these spanning/maximal rectangles will often
+     overlap each other.
+
+     Such a list makes it relatively easy to define operations like
+     window-is-onscreen or clamp-window-to-region or
+     shove-window-into-region.  Since we have a on-single-xinerama
+     constraint in addition to the onscreen constraint(s), we cache
+     number_xineramas + 1 of these lists in the workspace.  These lists
+     then only need to be updated whenever the workarea is (e.g. when strut
+     list change or screen or xinerama size changes).
+
+  4) Constraints can be user-action vs app-action oriented
+
+     Such differentiation requires special care for the constraints to be
+     consistent; e.g. if the user does something and one constraint
+     applies, then the app does something you have to be careful that the
+     constraint on the app action doesn't result in some jarring motion.
+
+     In particular, the constraints currently allow offscreen movement or
+     resizing for user actions only.  The way consistency is handled is
+     that at the end of the constraints, update_onscreen_requirements()
+     checks to see if the window is offscreen or split across xineramas and
+     updates window->require_fully_onscreen and
+     window->require_on_single_xinerama appropriately.
+
+  5) Avoid over-complification
+
+     The previous code tried to reform the constraints into terms of a
+     single variable.  This made the code rather difficult to
+     understand. ("This is a rather complicated fix for an obscure bug
+     that happened when resizing a window and encountering a constraint
+     such as the top edge of the screen.")  It also failed, even on the
+     very example for which it used as justification for the complexity
+     (bug 312104 -- when keyboard resizing the top of the window,
+     Metacity extends the bottom once the titlebar hits the top panel),
+     though the reason why it failed is somewhat mysterious as it should
+     have worked.  Further, it didn't really reform the constraints in
+     terms of a single variable -- there was both an x_move_delta and an
+     x_resize_delta, and the existence of both caused bug 109553
+     (gravity with simultaneous move and resize doesn't work)
+
+
+---------------------------------------------------------------------------
+Important points to remember
+---------------------------------------------------------------------------
+
+  - Inner vs Outer window
+
+    Note that because of how configure requests work and
+    meta_window_move_resize_internal() and friends are set up, that the
+    rectangles passed to meta_window_constrain() are with respect to inner
+    window positions instead of outer window positions (meaning that window
+    manager decorations are not included in the position/size).  For the
+    constraints that need to be enforced with respect to outer window
+    positions, you'll need to make use of the extend_by_frame() and
+    unextend_by_frame() functions.
+
+  - meta_window_move_resize_internal() accepts a really hairy set of
+    inputs.  See the huge comment at the beginning of that function.
+    constraints gets screwed up if that function can't sanitize the input,
+    so be very careful about that.  It used to be pretty busted.
+
+
+---------------------------------------------------------------------------
+Explanation of fields in the ConstraintInfo strut
+---------------------------------------------------------------------------
+
+As of the time of this writing, ConstraintInfo had the following fields:
+  orig
+  current
+  fgeom
+  action_type
+  is_user_action
+  resize_gravity
+  fixed_directions
+  work_area_xinerama
+  entire_xinerama
+  usable_screen_region
+  usable_xinerama_region
+
+A brief description of each and/or pointers to more information are found
+below:
+  orig
+    The previous position and size of the window, ignoring any window
+    decorations
+  current
+    The requested position and size of the window, ignoring any window
+    decorations.  This rectangle gets modified by the various constraints
+    to specify the allowed position closest to the requested position.
+  fgeom
+    The geometry of the window frame (i.e. "decorations"), if it exists.
+    Otherwise, it's a dummy 0-size frame for convenience (i.e. this pointer
+    is guaranteed to be non-NULL so you don't have to do the stupid check).
+  action_type
+    Whether the action being constrained is a move, resize, or a combined
+    move and resize.  Some constraints can run faster with this information
+    (e.g. constraining size increment hints or min size hints don't need to
+    do anything for pure move operations).  This may also be used for
+    providing slightly different behavior (e.g. clip-to-region instead of
+    shove-into-region for resize vs. moving operations), but doesn't
+    currently have a lot of use for this.
+  is_user_action
+    Used to determine whether the action being constrained is a user
+    action.  If so, certain parts of the constraint may be relaxed.  Note
+    that this requires care to get right; see item 4 of the basic ideas
+    section for more details.
+  resize_gravity
+    The gravity used in the resize operation, used in order to make sure
+    windows are resized correctly if constraints specify that their size
+    must be modified.  Explained further in the resize_gravity
+    vs. fixed_directions section.
+  fixed_directions
+    There may be multiple solutions to shoving a window back onscreen.
+    Typically, the shortest distance used is the solution picked, but if
+    e.g. an application only moved its window in a single direction, it's
+    more desirable that the window is shoved back in that direction than in
+    a different one.  fixed_directions facilitates that.  Explained further
+    in the resize_gravity vs. fixed_directions section.
+  work_area_xinerama
+    This region is defined in the workspace and just cached here for
+    convenience.  It is basically the area obtained by taking the current
+    xinerama, treating all partial struts as full struts, and then
+    subtracting all struts from the current xinerama region.  Useful
+    e.g. for enforcing maximization constraints.
+  entire_xinerama
+    Just a cache of the rectangle corresponding to the entire current
+    xinerama, including struts.  Useful e.g. for enforcing fullscreen
+    constraints.
+  usable_screen_region
+    The set of maximal/spanning rectangles for the entire screen; this
+    region doesn't overlap with any struts and helps to enforce
+    e.g. onscreen constraints.
+  usable_xinerama_region
+    The set of maximal/spanning rectangles for the current xinerama; this
+    region doesn't overlap with any struts on the xinerama and helps to
+    enforce e.g. the on-single-xinerama constraint.
+
+
+---------------------------------------------------------------------------
+Gory details of resize_gravity vs. fixed_directions
+---------------------------------------------------------------------------
+
+Note that although resize_gravity and fixed_directions look similar, they
+are used for different purposes:
+
+  - resize_gravity is only for resize operations and is used for
+    constraints unrelated to keeping a window within a certain region
+  - fixed_directions is for both move and resize operations and is
+    specifically for keeping a window within a specified region.
+
+Examples of where each are used:
+
+  - If a window is simultaneously moved and resized to the southeast corner
+    with SouthEastGravity, but it turns out that the window was sized to
+    something smaller than the minimum size hint, then the size_hints
+    constraint should resize the window using the resize_gravity to ensure
+    that the southeast corner doesn't move.
+  - If an application resizes itself so that it grows downward only (which
+    I note could be using any of three different gravities, most likely
+    NorthWest), and happens to put the southeast part of the window under a
+    partial strut, then the window needs to be forced back on screen.
+    (Yes, shoved onscreen and not clipped; see bug 136307).  It may be the
+    case that moving the window to the left results in less movement of the
+    window than moving the window up, which, in the absence of fixed
+    directions would cause us to chose moving to the left.  But since the
+    user knows that only the height of the window is changing, they would
+    find moving to the left weird (especially if this were a dialog that
+    had been centered on its parent).  It'd be better to shove the window
+    upwards so we make sure to keep the left and right sides fixed in this
+    case.  Note that moving the window upwards (or leftwards) is probably
+    totally against the gravity in this case; but that's okay because
+    gravity typically assumes there's more than enough onscreen space for
+    the resize and we only override the gravity when that assumption is
+    wrong.
+
+For the paranoid, a fixed directions might give an impossible to fulfill
+constraint (I don't think that's true currently in the code, but I haven't
+thought it through in a while).  If this ever becomes a problem, it should
+be relatively simple to throw out the fixed directions when this happens
+and rerun the constraint.  Of course, it might be better to rethink things
+to just avoid such a problem.
+
+The nitty gritty of what gets fixed:
+  User move:
+    in x direction - y direction fixed
+    in y direction - x direction fixed
+    in both dirs.  - neither direction fixed
+  User resize: (note that for clipping, only 1 side ever changed)
+    in x direction - y direction fixed (technically opposite x side fixed too)
+    in y direction - x direction fixed (technically opposite y side fixed too)
+    in both dirs.  - neither direction fixed
+  App move:
+    in x direction - y direction fixed
+    in y direction - x direction fixed
+    in both dirs.  - neither direction fixed
+  App resize
+    in x direction - y direction fixed
+    in y direction - x direction fixed
+    in 2 parallel directions (center side gravity) - other dir. fixed
+    in 2 orthogonal directions (corner gravity) - neither dir. fixed
+    in 3 or 4 directions (a center-like gravity) - neither dir. fixed
+  Move & resize
+    Treat like resize case though this will usually mean all four sides
+    change and result in neither direction being fixed
+  Note that in all cases, if neither direction moves it is likely do to a
+  change in struts and thus neither direction should be fixed despite the
+  lack of movement.

+To make choice of focus window consistent for each focus method, a
+number of guidelines should be followed.  (For purposes of discussion
+here, I'm excluding things like the panel and the desktop from
+"windows".  It is technically incorrect to do this, but I'm lazy and
+"windows" is shorter than something like "normal windows".  See the
+end of the discussion for how these special cases are handled.)  The
+basics are easy:
+
+Focus method  Behavior
+    click     When a user clicks on a window, focus it
+   sloppy     When an EnterNotify is received, focus the window
+    mouse     Same as sloppy, but also defocus on LeaveNotify
+
+Note that these choices (along with the choice that clicking on a
+window raises it for the click focus method) introduces the following
+invariants for focus from mouse activity:
+
+Focus method  Invariant
+    click     The window on top is focused
+   sloppy     If the mouse is in a window, then it is focused; if the
+              mouse is not in a window, then the most recently used
+              window is focused.
+    mouse     If the mouse is in a window, then it is focused; otherwise,
+              the designated "no_focus_window" is focused
+
+However, there are a number of cases where the current focus window
+becomes invalid and another should be chosen.  Some examples are when
+a focused window is closed or minimized, or when the user changes
+workspaces.  In these cases, there needs to be a rule consistent with
+the above about the new window to choose.
+
+Focus method  Behavior
+    click     Focus the most recently used window (same as the window
+              on top)
+   sloppy     Focus the window containing the pointer if there is such
+              a window, otherwise focus the most recently used window.
+    mouse     Focus the window containing the pointer if there is one,
+              otherwise focus the designated "no_focus_window".
+
+Note that "most recently used window", as used here, has a slightly
+different connotation than "most recent to have keyboard focus".  This
+is because when a user activates a window that is a transient, its
+ancestor(s) should be considered to be more recently used than other
+windows that have had the keyboard focus more recently.  (See bug
+157360; this may mean that the alt-tab order should also change
+simultaneously, although the current implementation does not do that.)
+
+Also, sometimes a new window will be mapped (e.g. unminimizing a
+window or launching a new application).  Most users want to interact
+with new windows right away, so these should typically be focused.
+This does conflict with the invariants for sloppy and mouse focus
+modes, so this wouldn't be true for a strict-pointer-focus mode.  For
+all other modes (non-strict-pointer-focus modes), there are only two
+cases in which a new window shouldn't be focused:
+
+  1) If the window takes a while to launch and the user starts
+     interacting with a different application, the new window should
+     not take focus.
+  2) If the window that will appear was not launched by the user
+     (error dialogs, instant messaging windows, etc.), then the window
+     should not take focus when it appears.
+
+To handle these cases, Metacity compares timestamps of the event that
+caused the launch and the timestamp of the last interaction with the
+focused window.  (Case 2 is handled by providing a special timestamp
+of 0 for the launch time, which ensures that the window that appears
+doesn't get focus)
+
+If the newly launched window isn't focused, some things should be done
+to alert the user that there is a window to work with:
+  1) The _NET_WM_DEMANDS_ATTENTION hint should be set
+  2) If the new window isn't modal for the focused window, it should
+     appear below the focused window so that it doesn't obscure the
+     focused window that the user is interacting with.
+  3) If the new window is modal to the focused window, the currently
+     focused window should lose focus but the modal window should
+     appear on top.
+
+Additionally, the user may decide to use the keyboard instead of the mouse
+to navigate between windows (referred to as "keynav").  This poses no
+problems for click-to-focus (because the same invariant can be
+maintained), but for sloppy and mouse focus it requires extra work to
+attempt to handle the INHERENTLY CONFLICTING CONSTRAINTS.  Metacity does
+this by having a mouse_mode boolean used to determine which of the two
+sets of invariants holds.  This mode is set according to which method was
+most recently used to choose a focus window:
+  1) When receiving EnterNotify/LeaveNotify events from mouse movement, set
+     mouse_mode to TRUE.
+  2) When using keynav to choose a focus window (e.g. alt-tab, alt-esc,
+     move-window-to-workspace keybindings), set mouse_mode to FALSE.
+  3) When handling events that don't choose a focus window but rather need
+     a focus_window chosen for them (e.g. switch-to-workspace keybindings),
+     don't change the mouse_mode and just use the current value.
+Note that grabs present a special case since they can generate EnterNotify
+and LeaveNotify events without using the mouse, thus these events should be
+ignored when the crossing mode is NotifyGrab or NotifyUngrab.  THIS
+MOUSENAV/KEYNAV MODERATION METHOD IS NOT PERFECT--there are corner cases
+when trying to mix-and-match between mousenav and keynav simultaneously
+that cause problems; but it appears to be the most reasonable tradeoff and
+works well in most cases, especially if the user sticks to just mousenav
+for a long time or just keynav for a long time.
+
+Finally, windows of type WM_DOCK or WM_DESKTOP (e.g. the desktop and
+the panel) present a special case, at least partially due to the lack
+of decorations.  For WM_DESKTOP windows, we only focus them if the
+user explicitly requests it (e.g. clicks on the window, uses
+Ctrl-Alt-Tab to navigate to it, uses a keybinding to show the desktop,
+etc.).  For WM_DOCK windows, we do not focus unless we receive a very
+explicit request (e.g. Ctrl-Alt-Tab or a _NET_ACTIVE_WINDOW message;
+not normal clicks).

+
+Addendum on sloppy and mouse focus
+  You may occasionally hear people refer to sloppy or mouse focus
+  modes as inherently buggy.  This is what they mean by that:
+
+  1) Keynav doesn't maintain the same invariants as mouse navigation
+     for these focus modes; switching back and forth between
+     navigation methods, therefore, may have or appear to have
+     inconsistencies.  Examples:
+     a) If the user uses Alt-Tab to change the window with focus, then
+        starts to move the mouse, at that moment the window where the
+        mouse is does not have focus.
+     b) Users expect that a workspace they previously used will not
+        change when the return to it.  This means things like window
+        position and stacking order, but also the focus window.
+        Unfortunately, using the original focus window (which would be
+        the most recently used window on that workspace) will
+        sometimes conflict with the invariants for mouse and sloppy
+        focus modes.  Users are much more surprised by the invariant
+        being broken than by having the focus window changed (see bug
+        94545 and probably others), so we maintain the invariant.
+        This only matters when using Ctrl-Alt-Arrow to switch
+        workspaces instead of clicking in the workspace switcher, so
+        this really is a keynav vs mouse issue.  Either that, or a
+        windows-are-being-mapped exception.  ;-)
+     c) Opening a menu, then moving the mouse to a different window,
+        and then pressing escape to dismiss the menu will result in
+        the window containing the mouse not being focused.  This is
+        actually correct behavior (because pressing escape shows that
+        the user is using key navigation to interact with the window
+        containing the menu) but is one of those hard-to-get-right
+        keynav and mouse focus mixture cases.  (See bug 101190 for
+        more details)
+     d) Similar to (c), moving the mouse off the menu doesn't immediately
+        focus the window that the mouse goes over, due to an application
+        grab (we couldn't change this and wouldn't want to, but
+        technically it does break the invariant).
+     e) If mouse_mode is off and the user does something to cause focus to
+        change (e.g. switch workspaces, close or minimize a window, etc.)
+        and simultaneously tries to move the mouse, the choice of which
+        window to focus is inherently race-y.  (You probably can't satisfy
+        both keynav and mousenav invariants simultaneously...)
+  2) The sloppy/mouse invariants are often not strictly maintained;
+     for example, we provide an exception to the invariant for newly
+     mapped windows.  (Most find that not allowing this exception is
+     confusing)
+  3) There are an awful lot of little cases to handle to get any focus
+     mode right, even for click-to-focus.  Since mouse and sloppy
+     focus have sometimes been hard to even determine what correct
+     behavior is, it is much harder to get them completely right.
+     Plus mouse and sloppy focus users are a minority, decreasing the
+     motivation of window manager implementors to get those focus
+     modes right.
+  4) Because of -1-, -2-, and -3-, implementations are often buggy or
+     inconsistent and people form their opinions from usage of these
+     implementations.
+  5) Sloppy focus suffers from a bit of a discoverability problem (for
+     example, I have seen a scientist sit down to a computer for which
+     sloppy focus was in use and take a few minutes before figuring
+     out how window activation worked; granted the layout of the
+     windows in that situation was a bit unusual but it still
+     illustrates that sloppy focus is harder than it should be to
+     figure out).  Mouse focus solves this problem; however, people
+     that have experience with other computing environments are
+     accustomed to being able to move their mouse outside the window
+     they are working with and still continue interacting with that
+     window, which conflicts with mouse focus.
