Fix input and bounding shapes

1) We need to select for shape events
2) For decorated windows, we don't want to apply any input
   shape, because the frame is always rectangular and eats
   all the input
3) For undecorated windows, the "has input shape" check is
   wrong if the window has a bounding shape but not an input
   shape

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

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

+  Minimal Building/Testing Environment
+  Relevant standards and X properties
+  Debugging and testing
+    Debugging logs
+    Adding information to the log
+    Valgrind
+    Testing Utilities

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

+
+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.
