+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.

+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.
+
+Overview
+  Administrative issues
+  Minimal Building/Testing Environment
+  Relevant standards and X properties
+  Debugging and testing
+    Debugging logs
+    Adding information to the log
+    Valgrind
+    Testing Utilities
+  Technical gotchas to keep in mind
+  Other important reading
+    Extra reading
+    Ideas for tasks to work on
+
+
+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

+  These are:
+    http://pobox.com/~hp/features.html
+    rationales.txt
+    doc/code-overview.txt
+
+  It pays to read http://pobox.com/~hp/features.html in order
+  to understand the philosophy of Metacity.
+
+  The rationales.txt file has two things: (1) a list of design choices with
+  links in the form of bugzilla bugs that discuss the issue, and (2) a list
+  outstanding bug categories, each of which is tracked by a particular
+  tracker bug in bugzilla from which you can find several closely related
+  bug reports.
+
+  doc/code-overview.txt provides a fairly good overview of the code,
+  including coverage of the function of the various files, the main
+  structures and their relationships, and places to start looking in the
+  code tailored to general categories of tasks.
+
+  Ideas for tasks to work on
+
+  There are a variety of things you could work on in the code.  You may
+  have ideas of your own, but in case you don't, let me provide a list of
+  ideas you could choose from:
+
+  If you're ambitious, there's a list of things Havoc made that he'd really
+  like to see tackled, which you can find at
+  http://log.ometer.com/2004-05.html.  Be sure to double check with someone
+  to make sure the item is still relevant if you're interested in one of
+  these.  Another place to look for ideas, of course, is bugzilla.  One can
+  just do queries and look for things that look fixable.
+
+  However, perhaps the best way of getting ideas of related tasks to work
+  on, is to look at the second half of the rationales.txt file, which tries
+  to group bugs by type.

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

-# Mutter
-
-Mutter is a Wayland display server and X11 window manager and compositor library.
-
-When used as a Wayland display server, it runs on top of KMS and libinput. It
-implements the compositor side of the Wayland core protocol as well as various
-protocol extensions. It also has functionality related to running X11
-applications using Xwayland.
-
-When used on top of Xorg it acts as a X11 window manager and compositing manager.
-
-It contains functionality related to, among other things, window management,
-window compositing, focus tracking, workspace management, keybindings and
-monitor configuration.
-
-Internally it uses a fork of Cogl, a hardware acceleration abstraction library
-used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a
-scene graph and user interface toolkit.
-
-Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and
-by  Gala, elementary OS's window manager. It can also be run standalone, using
-the  command "mutter", but just running plain mutter is only intended for
-debugging purposes.

- *
- * #ClutterActorAccessible implements the required ATK interfaces of [class@Clutter.Actor]
- * exposing the common elements on each actor (position, extents, etc).
- */
-
-/*
- *
- * IMPLEMENTATION NOTES:
- *
- * ####
- *
- * Focus: clutter hasn't got the focus concept in the same way that GTK, but it
- * has a key focus managed by the stage. Basically any actor can be focused using
- * clutter_stage_set_key_focus. So, we will use this approach: all actors are
- * focusable, and we get the currently focused using clutter_stage_get_key_focus
- * This affects focus related stateset and some atk_component focus methods (like
- * grab focus).
- *
- * In the same way, we will manage the focus state change management
- * on the cally-stage object. The reason is avoid missing a focus
- * state change event if the object is focused just before the
- * accessibility object being created.
- *
- * #AtkAction implementation: on previous releases ClutterActor added
- * the actions "press", "release" and "click", as at that time some
- * general-purpose actors like textures were directly used as buttons.
- *
- * But now, new toolkits appeared, providing high-level widgets, like
- * buttons. So in this environment, it doesn't make sense to keep
- * adding them as default.
- *
- * Anyway, current implementation of AtkAction is done at ClutterActorAccessible
- * providing methods to add and remove actions. This is based on the
- * one used at gailcell, and proposed as a change on #AtkAction
- * interface:
- *
- *  https://bugzilla.gnome.org/show_bug.cgi?id=649804

- * @realize: virtual function, used to allocate resources for the actor;
- *   it should chain up to the parent's implementation. This virtual
- *   function is deprecated and should not be overridden in newly
- *   written code.
- * @unrealize: virtual function, used to deallocate resources allocated
- *   in ::realize; it should chain up to the parent's implementation. This
- *   function is deprecated and should not be overridden in newly

- * @map: virtual function for containers and composite actors, to
- *   map their children; it must chain up to the parent's implementation.
- *   Overriding this function is optional.
- * @unmap: virtual function for containers and composite actors, to
- *   unmap their children; it must chain up to the parent's implementation.
- *   Overriding this function is optional.
- * @paint: virtual function, used to paint the actor
- * @get_preferred_width: virtual function, used when querying the minimum
- *   and natural widths of an actor for a given height; it is used by
- *   clutter_actor_get_preferred_width()
- * @get_preferred_height: virtual function, used when querying the minimum
- *   and natural heights of an actor for a given width; it is used by
- *   clutter_actor_get_preferred_height()
- * @allocate: virtual function, used when setting the coordinates of an
- *   actor; it is used by clutter_actor_allocate(); when overriding this
- *   function without chaining up, clutter_actor_set_allocation() must be
- *   called and children must be allocated by the implementation, when
- *   chaining up though, those things will be done by the parent's
- *   implementation.
- * @apply_transform: virtual function, used when applying the transformations
- *   to an actor before painting it or when transforming coordinates or
- *   the allocation; if the transformation calculated by this function may
- *   have changed, the cached transformation must be invalidated by calling
- *   clutter_actor_invalidate_transform(); it must chain up to the parent's
- *   implementation
- * @parent_set: signal class handler for the [signal@Clutter.Actor::parent-set]
- * @destroy: signal class handler for [signal@Clutter.Actor::destroy]. It must

- * @pick: virtual function, used to draw an outline of the actor with

-/**
- * ClutterBindConstraint:
- *
- * A constraint binding the position or size of an actor
- *
- * #ClutterBindConstraint is a [class@Constraint] that binds the
- * position or the size of the [class@Actor] to which it is applied
- * to the the position or the size of another [class@Actor], or
- * "source".
- *
- * An offset can be applied to the constraint, to avoid overlapping. The offset
- * can also be animated. For instance, the following code will set up three
- * actors to be bound to the same origin:
- *
- * ```c
- * // source
- * rect[0] = clutter_actor_new ();
- * clutter_actor_set_background_color (rect[0], &red_color);
- * clutter_actor_set_position (rect[0], x_pos, y_pos);
- * clutter_actor_set_size (rect[0], 100, 100);
- *
- * // second rectangle
- * rect[1] = clutter_actor_new ();
- * clutter_actor_set_background_color (rect[1], &green_color);
- * clutter_actor_set_size (rect[1], 100, 100);
- * clutter_actor_set_opacity (rect[1], 0);
- *
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_X, 0.0);
- * clutter_actor_add_constraint_with_name (rect[1], "green-x", constraint);
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_Y, 0.0);
- * clutter_actor_add_constraint_with_name (rect[1], "green-y", constraint);
- *
- * // third rectangle
- * rect[2] = clutter_actor_new ();
- * clutter_actor_set_background_color (rect[2], &blue_color);
- * clutter_actor_set_size (rect[2], 100, 100);
- * clutter_actor_set_opacity (rect[2], 0);
- *
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_X, 0.0);
- * clutter_actor_add_constraint_with_name (rect[2], "blue-x", constraint);
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_Y, 0.0);
- * clutter_actor_add_constraint_with_name (rect[2], "blue-y", constraint);
- * ```
- *
- * The following code animates the second and third rectangles to "expand"
- * them horizontally from underneath the first rectangle:
- *
- * ```c
- * clutter_actor_animate (rect[1], CLUTTER_EASE_OUT_CUBIC, 250,
- *                        "@constraints.green-x.offset", 100.0,
- *                        "opacity", 255,
- *                        NULL);
- * clutter_actor_animate (rect[2], CLUTTER_EASE_OUT_CUBIC, 250,
- *                        "@constraints.blue-x.offset", 200.0,
- *                        "opacity", 255,

-/**
- * ClutterBindingPool
- *
- * Pool for key bindings
- *
- * #ClutterBindingPool is a data structure holding a set of key bindings.
- * Each key binding associates a key symbol (eventually with modifiers)
- * to an action. A callback function is associated to each action.
- *
- * For a given key symbol and modifier mask combination there can be only one
- * action; for each action there can be only one callback. There can be
- * multiple actions with the same name, and the same callback can be used
- * to handle multiple key bindings.
- *
- * Actors requiring key bindings should create a new #ClutterBindingPool
- * inside their class initialization function and then install actions
- * like this:
- *
- * ```c
- * static void
- * foo_class_init (FooClass *klass)
- * {
- *   ClutterBindingPool *binding_pool;
- *
- *   binding_pool = clutter_binding_pool_get_for_class (klass);
- *
- *   clutter_binding_pool_install_action (binding_pool, "move-up",
- *                                        CLUTTER_Up, 0,
- *                                        G_CALLBACK (foo_action_move_up),
- *                                        NULL, NULL);
- *   clutter_binding_pool_install_action (binding_pool, "move-up",
- *                                        CLUTTER_KP_Up, 0,
- *                                        G_CALLBACK (foo_action_move_up),
- *                                        NULL, NULL);
- * }
- * ```
- *
- * The callback has a signature of:
- *
- * ```c
- *    gboolean (* callback) (GObject             *instance,
- *                           const gchar         *action_name,
- *                           guint                key_val,
- *                           ClutterModifierType  modifiers,
- *                           gpointer             user_data);
- * ```
- *
- * The actor should then override the [signal@Actor::key-press-event] and
- * use [method@BindingPool.activate] to match a [struct@Event] key event
- * structure to one of the actions:
- *
- * ```c
- *   ClutterBindingPool *pool;
- *
- *   // retrieve the binding pool for the type of the actor
- *   pool = clutter_binding_pool_find (G_OBJECT_TYPE_NAME (actor));
- *
- *   // activate any callback matching the key symbol and modifiers
- *   // mask of the key event. the returned value can be directly
- *   // used to signal that the actor has handled the event.
- *   return clutter_binding_pool_activate (pool,
- *                                         key_event->keyval,
- *                                         key_event->modifier_state,
- *                                         G_OBJECT (actor));
- * ```
- *
- * The [method@BindingPool.activate] function will return %FALSE if
- * no action for the given key binding was found, if the action was
- * blocked (using [method@BindingPool.block_action]) or if the
- * key binding handler returned %FALSE.

-/**
- * ClutterBlur:
- *
- * Blur textures
- *
- * #ClutterBlur is a moderately fast gaussian blur implementation.
- *
- * # Optimizations
- *
- * There are a number of optimizations in place to make this blur implementation
- * real-time. All in all, the implementation performs best when using large
- * blur-radii that allow downscaling the texture to smaller sizes, at small
- * radii where no downscaling is possible this can easily halve the framerate.
- *
- * ## Multipass
- *
- * It is implemented in 2 passes: vertical and horizontal.
- *
- * ## Downscaling
- *
- * #ClutterBlur uses dynamic downscaling to speed up blurring. Downscaling
- * happens in factors of 2 (the image is downscaled either by 2, 4, 8, 16, …)
- * and depends on the blur radius, the texture size, among others.
- *
- * The texture is drawn into a downscaled framebuffer; the blur passes are
- * applied on the downscaled texture contents; and finally, the blurred
- * contents are drawn
- * upscaled again.
- *
- * ## Hardware Interpolation
- *
- * This blur implementation cuts down the number of sampling operations by
- * exploiting the hardware interpolation that is performed when sampling between
- * pixel boundaries. This technique is described at:
- *
- * http://rastergrid.com/blog/2010/09/efficient-gaussian-blur-with-linear-sampling/
- *
- * ## Incremental gauss-factor calculation
- *
- * The kernel values for the gaussian kernel are computed incrementally instead
- * of running the expensive calculations multiple times inside the blur shader.
- * The implementation is based on the algorithm presented by K. Turkowski in
- * GPU Gems 3, chapter 40:
- *
- * https://developer.nvidia.com/gpugems/GPUGems3/gpugems3_ch40.html

-/**
- * ClutterClickAction:
- *
- * Action for clickable actors
- *
- * #ClutterClickAction is a sub-class of [class@Action] that implements
- * the logic for clickable actors, by using the low level events of
- * [class@Actor], such as [signal@Actor::button-press-event] and
- * [signal@Actor::button-release-event], to synthesize the high level
- * [signal@ClickAction::clicked] signal.
- *
- * To use #ClutterClickAction you just need to apply it to a [class@Actor]
- * using [method@Actor.add_action] and connect to the
- * [signal@ClickAction::clicked] signal:
- *
- * ```c
- *   ClutterAction *action = clutter_click_action_new ();
- *
- *   clutter_actor_add_action (actor, action);
- *
- *   g_signal_connect (action, "clicked", G_CALLBACK (on_clicked), NULL);
- * ```
- *
- * #ClutterClickAction also supports long press gestures: a long press is
- * activated if the pointer remains pressed within a certain threshold (as
- * defined by the [property@ClickAction:long-press-threshold] property) for a
- * minimum amount of time (as the defined by the
- * [property@ClickAction:long-press-duration] property).
- * The [signal@ClickAction::long-press] signal is emitted multiple times,
- * using different [enum@LongPressState] values; to handle long presses
- * you should connect to the [signal@ClickAction::long-press] signal and
- * handle the different states:
- *
- * ```c
- *   static gboolean
- *   on_long_press (ClutterClickAction    *action,
- *                  ClutterActor          *actor,
- *                  ClutterLongPressState  state)
- *   {
- *     switch (state)
- *       {
- *       case CLUTTER_LONG_PRESS_QUERY:
- *         // return TRUE if the actor should support long press
- *         // gestures, and FALSE otherwise; this state will be
- *         // emitted on button presses
- *         return TRUE;
- *
- *       case CLUTTER_LONG_PRESS_ACTIVATE:
- *         // this state is emitted if the minimum duration has
- *         // been reached without the gesture being cancelled.
- *         // the return value is not used
- *         return TRUE;
- *
- *       case CLUTTER_LONG_PRESS_CANCEL:
- *         // this state is emitted if the long press was cancelled;
- *         // for instance, the pointer went outside the actor or the
- *         // allowed threshold, or the button was released before
- *         // the minimum duration was reached. the return value is
- *         // not used
- *         return FALSE;
- *       }
- *   }

-/**
- * ClutterConstraint:
- * 
- * Abstract class for constraints on position or size
- *
- * #ClutterConstraint is a base abstract class for modifiers of a #ClutterActor
- * position or size.
- *
- * A #ClutterConstraint sub-class should contain the logic for modifying
- * the position or size of the #ClutterActor to which it is applied, by
- * updating the actor's allocation. Each #ClutterConstraint can change the
- * allocation of the actor to which they are applied by overriding the
- * [vfunc@Clutter.Constraint.update_allocation] virtual function.
- *
- * ## Using Constraints
- *
- * Constraints can be used with fixed layout managers, like
- * #ClutterFixedLayout, or with actors implicitly using a fixed layout
- * manager, like #ClutterGroup and #ClutterStage.
- *
- * Constraints provide a way to build user interfaces by using
- * relations between #ClutterActors, without explicit fixed
- * positioning and sizing, similarly to how fluid layout managers like
- * #ClutterBoxLayout lay out their children.
- *
- * Constraints are attached to a #ClutterActor, and are available
- * for inspection using [method@Clutter.Actor.get_constraints].
- *
- * Clutter provides different implementation of the #ClutterConstraint
- * abstract class, for instance:
- *
- *  - #ClutterAlignConstraint, a constraint that can be used to align
- *  an actor to another one on either the horizontal or the vertical
- *  axis, using a normalized value between 0 and 1.
- *  - #ClutterBindConstraint, a constraint binds the X, Y, width or height
- *  of an actor to the corresponding position or size of a source actor,
- *  with or without an offset.
- *  - #ClutterSnapConstraint, a constraint that "snaps" together the edges
- *  of two #ClutterActors; if an actor uses two constraints on both its
- *  horizontal or vertical edges then it can also expand to fit the empty
- *  space.
- *
- * It is important to note that Clutter does not avoid loops or
- * competing constraints; if two or more #ClutterConstraints
- * are operating on the same positional or dimensional attributes of an
- * actor, or if the constraints on two different actors depend on each
- * other, then the behavior is undefined.
- *
- * ## Implementing a ClutterConstraint
- *
- * Creating a sub-class of #ClutterConstraint requires the
- * implementation of the [vfunc@Clutter.Constraint.update_allocation]
- * virtual function.
- *
- * The `update_allocation()` virtual function is called during the
- * allocation sequence of a #ClutterActor, and allows any #ClutterConstraint
- * attached to that actor to modify the allocation before it is passed to
- * the actor's #ClutterActorClass.allocate() implementation.
- *
- * The #ClutterActorBox passed to the `update_allocation()` implementation
- * contains the original allocation of the #ClutterActor, plus the eventual
- * modifications applied by the other #ClutterConstraints, in the same order
- * the constraints have been applied to the actor.
- *
- * It is not necessary for a #ClutterConstraint sub-class to chain
- * up to the parent's implementation.
- *
- * If a #ClutterConstraint is parametrized - i.e. if it contains
- * properties that affect the way the constraint is implemented - it should
- * call clutter_actor_queue_relayout() on the actor to which it is attached
- * to whenever any parameter is changed. The actor to which it is attached
- * can be recovered at any point using clutter_actor_meta_get_actor().

- * ClutterDeformEffect:
- *
- * A base class for effects deforming the geometry of an actor
- *
- * #ClutterDeformEffect is an abstract class providing all the plumbing
- * for creating effects that result in the deformation of an actor's
- * geometry.
- *
- * #ClutterDeformEffect uses offscreen buffers to render the contents of
- * a #ClutterActor and then the Cogl vertex buffers API to submit the
- * geometry to the GPU.
- *
- * ## Implementing ClutterDeformEffect
- *
- * Sub-classes of #ClutterDeformEffect should override the
- * [vfunc@Clutter.DeformEffect.deform_vertex] virtual function; this function
- * is called on every vertex that needs to be deformed by the effect.
- * Each passed vertex is an in-out parameter that initially contains the
- * position of the vertex and should be modified according to a specific
- * deformation algorithm.

-/**
- * ClutterEffect:
- *
- * Base class for actor effects
- *
- * The #ClutterEffect class provides a default type and API for creating
- * effects for generic actors.
- *
- * Effects are a #ClutterActorMeta sub-class that modify the way an actor
- * is painted in a way that is not part of the actor's implementation.
- *
- * Effects should be the preferred way to affect the paint sequence of an
- * actor without sub-classing the actor itself and overriding the
- * [vfunc@Clutter.Actor.paint] virtual function.
- *
- * ## Implementing a ClutterEffect
- *
- * Creating a sub-class of #ClutterEffect requires overriding the
- * [vfunc@Clutter.Effect.paint] method. The implementation of the function should look
- * something like this:
- *
- * ```c
- * void effect_paint (ClutterEffect *effect, ClutterEffectPaintFlags flags)
- * {
- *   // Set up initialisation of the paint such as binding a
- *   // CoglOffscreen or other operations
- *
- *   // Chain to the next item in the paint sequence. This will either call
- *   // ‘paint’ on the next effect or just paint the actor if this is
- *   // the last effect.
- *   ClutterActor *actor =
- *     clutter_actor_meta_get_actor (CLUTTER_ACTOR_META (effect));
- *
- *   clutter_actor_continue_paint (actor);
- *
- *   // perform any cleanup of state, such as popping the CoglOffscreen
- * }
- * ```
- *
- * The effect can optionally avoid calling clutter_actor_continue_paint() to skip any
- * further stages of the paint sequence. This is useful for example if the effect
- * contains a cached image of the actor. In that case it can optimise painting by
- * avoiding the actor paint and instead painting the cached image.
- *
- * The %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag is useful in this case. Clutter will set
- * this flag when a redraw has been queued on the actor since it was last painted. The
- * effect can use this information to decide if the cached image is still valid.
- *
- * ## A simple ClutterEffect implementation
- *
- * The example below creates two rectangles: one will be painted "behind" the actor,
- * while another will be painted "on top" of the actor.
- *
- * The #ClutterActorMetaClass.set_actor() implementation will create the two pipelines
- * used for the two different rectangles; the #ClutterEffectClass.paint() implementation
- * will paint the first pipeline using cogl_rectangle(), before continuing and then it
- * will paint paint the second pipeline after.
- *
- * ```c
- *  typedef struct {
- *    ClutterEffect parent_instance;
- *
- *    CoglPipeline *rect_1;
- *    CoglPipeline *rect_2;
- *  } MyEffect;
- *
- *  typedef struct _ClutterEffectClass MyEffectClass;
- *
- *  G_DEFINE_TYPE (MyEffect, my_effect, CLUTTER_TYPE_EFFECT);
- *
- *  static void
- *  my_effect_set_actor (ClutterActorMeta *meta,
- *                       ClutterActor     *actor)
- *  {
- *    MyEffect *self = MY_EFFECT (meta);
- *    CoglColor color;
- *
- *    // Clear the previous state //
- *    if (self->rect_1)
- *      {
- *        g_object_unref (self->rect_1);
- *        self->rect_1 = NULL;
- *      }

- *    self->rect_1 = cogl_pipeline_new ();
- *    cogl_color_init_from_4f (&color, 1.0, 1.0, 1.0, 1.0);
- *    cogl_pipeline_set_color (self->rect_1, &color);
- *
- *    // Create a green pipeline
- *    self->rect_2 = cogl_pipeline_new ();
- *    cogl_color_init_from_4f (&color, 0.0, 1.0, 0.0, 1.0);
- *    cogl_pipeline_set_color (self->rect_2, &color);

- *    cogl_rectangle (0, 0, width / 2, height / 2);
- *
- *    // Continue to the rest of the paint sequence
- *    clutter_actor_continue_paint (self->actor);

- * clutter_effect_queue_repaint:
- * @effect: A #ClutterEffect which needs redrawing
- *
- * Queues a repaint of the effect. The effect can detect when the ‘paint’
- * method is called as a result of this function because it will not
- * have the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag set. In that case the
- * effect is free to assume that the actor has not changed its
- * appearance since the last time it was painted so it doesn't need to
- * call clutter_actor_continue_paint() if it can draw a cached
- * image. This is mostly intended for effects that are using a
- * %CoglOffscreen to redirect the actor (such as
- * %ClutterOffscreenEffect). In that case the effect can save a bit of
- * rendering time by painting the cached texture without causing the
- * entire actor to be painted.
- *
- * This function can be used by effects that have their own animatable
- * parameters. For example, an effect which adds a varying degree of a
- * red tint to an actor by redirecting it through a CoglOffscreen
- * might have a property to specify the level of tint. When this value
- * changes, the underlying actor doesn't need to be redrawn so the
- * effect can call clutter_effect_queue_repaint() to make sure the
- * effect is repainted.
- *
- * Note however that modifying the position of the parent of an actor
- * may change the appearance of the actor because its transformation
- * matrix would change. In this case a redraw wouldn't be queued on
- * the actor itself so the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY would still
- * not be set. The effect can detect this case by keeping track of the
- * last modelview matrix that was used to render the actor and
- * verifying that it remains the same in the next paint.
- *
- * Any other effects that are layered on top of the passed in effect
- * will still be passed the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag. If
- * anything queues a redraw on the actor without specifying an effect
- * or with an effect that is lower in the chain of effects than this
- * one then that will override this call. In that case this effect
- * will instead be called with the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY
- * flag set.
