If a window had no title property set, then the
application-not-responding dialog would cause Mutter to crash
because window->title was NULL; handle that case and use the
string "Application is not responding."

Command line arguments are supposed to be in the locale encoding,
not UTF-8, and Zenity decodes command line string command line
arguments with this assumption using GOption.
There was a half-hearted attempt to deal with this in delete.c,
but it wasn't correct since it immediately mixed the window title,
converted to the locale encoding with a UTF-8 message.
https://bugzilla.gnome.org/show_bug.cgi?id=649114
As a library, libmutter should not be setting the default translation
domain to point to itself.
Also, move the bindtextdomain() call earlier
(meta_get_option_context), so that translations of command-line
options will be available.
We could call textdomain() in mutter.c, but there's no need to, since
mutter uses dgettext() everywhere anyway.

Previously, the restart command hardcoded "mutter" as the binary name.
This commit changes it to use g_get_prgname() which has a better chance
of being correct (and it does fix session saving for gnome-shell).
Now that mutter is a library, it might be more correct (but also
much higher overhead) to add api for setting these things from
the outside.

An ARGB window with a frame is likely something like a transparent
terminal. It looks awful (and breaks transparency) to draw a big
opaque black shadow under the window, so clip out the region under
the terminal from the shadow we draw.
Add meta_window_get_frame_bounds() to get a cairo region for the
outer bounds of the frame of a window, and modify the frame handling
code to notice changes to the frame shape and discard a cached
region. meta_frames_apply_shapes() is refactored so we can extract
meta_frames_get_frame_bounds() from it.
https://bugzilla.gnome.org/show_bug.cgi?id=635268
It's useful to get frame shapes and manipulate them within Mutter, for
example so that the compositor can use them to clip drawing.
For this, we'll need the regions as cairo regions not X regions, so
convert frame shaping code to work in terms of cairo_region_t.
https://bugzilla.gnome.org/show_bug.cgi?id=635268
Using MetaWindowActor.opacity for _NET_WM_WINDOW_OPACITY makes it
difficult to implement effects like fading a window in on map.
Instead, set the opacity on the MetaShadedTexture child and use
it when drawing the shadow.
Since the check MetaWindowGroup does on meta_actor_get_paint_opacity()
no longer covers this, we need to handle the opacity in
meta_window_actor_get_obscured_region() explicitly.

If a window can not be tiled, e.g. due to its minimum size hints,
dragging away from the top after activating the maximize tile preview
does not cancel the maximization request, the only way to do so is by
hitting Escape.
To fix, reset the tiling state in the maximize-tile code path as
well if necessary.

Apparently the "fox" toolkit doesn't set WM_CLIENT_MACHINE; while we

Since appears-focus only propagates up from modal dialogs, if an
application removed the modal hint from a dialog before destroying it,
then its parent would be left with a stray reference to it in
attached_focus_window, causing it to be permanently appears-focused.
The obvious fix, calling meta_window_propagate_focus_appearance() when
the modal hint is removed, tends to cause noticeable flashing, because
the window will get drawn unfocused and then focused again.
So instead we just change meta_window_propagate_focus_appearance() to
check the window type only when focusing in, not when focusing out.
This would also cause flashing, but in this case we can avoid it by
not notifying the change in appears-focus on the parent window if it
is the expected_focus_window (which it will be by this point). (This
does mean though that if something weird happens and the window
doesn't end up becoming the focus window, it won't get redrawn
unfocused until something else forces it to.)
https://bugzilla.gnome.org/show_bug.cgi?id=647613
We need to redraw a window's shadow any time the value of
meta_window_appears_focused() changes. So make that into a property so
we can get notifications on it.

This is necessary for gnome-shell to know whether it should try to

un-export util.h or fix it.

As the position of attached modal dialogs is determined entirely
by the position of the parent window, the dialog may end up

Commit 96c43866 changed the tiling behavior to prefer edge tiling
over maximization in corner cases (well, quite literally). As a
side effect, it only allows untiling of edge-tiled windows by
dragging the window towards the correct edge.
This patch restores the old behavior for untiling, while keeping
the new behavior for untiled windows.
https://bugzilla.gnome.org/show_bug.cgi?id=645455
For tiling, we check whether the pointer is near the edges of
the monitor where the pointer is located, so checking that the

In a performance or regression testing environment, we may want to

This made sense back in the day of stateless window managers,

This adds a preference that when enabled makes all windows not on
the primary monitor be visible on all workspaces (i.e. not part of the
workspace switching handling).
https://bugzilla.gnome.org/show_bug.cgi?id=609258
Sometimes on_all_workspaces is requested by the client/user, and sometimes
its calculated implicitly due to internal state. We split this up so that
we know when the user has explicitly asked for sticky window, when e.g.
setting wmspec properties or storing session info.
on_all_workspaces means this window is visible on all workspaces.
on_all_workspaces_requested, means the user explicitly made the window
sticky somehow (via imported session, _NET_WM_STATE from another wm,
toggled in the window menu, etc). It always implies on_all_workspaces is
TRUE.
Right now the only time we set on_all_workspaces is for override-redirect
windows, but later we can add a "windows on non-primary monitor are not
part of the workspace switching" feature.

The latter move method will place the window by the origin of the

When reload_net_wm_state() is called at startup to read the initial
value of _NET_WM_STATE, it was calling recalc_window_type(), but not
recalc_features(), which meant that, eg, meta->skip_taskbar would
never get initialized from meta->wm_state_skip_taskbar, which meant
that next time mutter went to update the window's _NET_WM_STATE, it
would overwrite the app-specified initial values. Fix that.
(In metacity, this bug is masked by the fact that recalc_features()
gets called when reading the intial value of WM_NORMAL_HINTS, which
comes after _NET_WM_STATE in metacity's prop_hooks_table. In mutter,
the table got reordered at some point, exposing the bug.)

If mutter is going to be a "real" library, then it should install its
includes so that users can do
#include <meta/display.h>
rather than
#include <display.h>
So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.
There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.

Move all of the mutter code into a new libmutter-wm.so, split its
main() method into meta_get_option_context(), meta_init() and
meta_run(), add methods for using in-process plugins, and add
libmutter-wm.pc pointing to the new library.
The mutter binary is now just a tiny program that links against
libmutter-wm. The --version and --mutter-plugins options are handled
at the mutter level, not in libmutter-wm, and a few strange unused
command-line options (--no-force-fullscreen and --no-tab-popup) have
been removed.

It looks amazingly lame if we simply call exit() during logout. While
it's true that for applications that use XSMP, gnome-session will
close them before us, that doesn't do anything for non-XSMP apps,
which we really hope is the common case.
Instead, we just go away when the X server does.
https://bugzilla.gnome.org/show_bug.cgi?id=643437
For GNOME Shell, we need to grab our DBus names *before* we talk XSMP.
gnome-session takes our XSMP connection as "I'm ready", and starts
running all the other random crud that people dropped in as autostart
files. But for example, we need to have claimed
org.freedesktop.Notifications before a lot of said crud starts.
This requires a plugin API version bump.
Misc: Move handling of --version way earlier in main() where
it should be; no point having it wedged after plugin handling.
If we handle a key event then passing it to GTK+ as well can only
cause confusion. Normally GTK+ would do nothing with a key event for
some window it doesn't know about, but plugins might be doing more
things with the GTK+ event queue.

If a plugin was explicitly specified, falling back to the default
silently is bad; a manager component like gnome-session can
do a better job of handling this scenario.

unresolved symbols.
But there are obviously others, like the file being missing or
corrupt.

Similar to the recently added 'size-changed' signal, we may want to do
something in response to a window being repositioned without waiting for

point.)

If we are previewing hidden windows, we might be previewing them in a context
like a thumbnail view of a workspace where we care about positioning. So, instead
of waiting until the window is first actually shown to place it, if

visibility, even if we don't end up showing it.

A plugin that does workspace management on its on may want to set the
workspace layout without having to deal with putting a property

When we delete a workspace before the active workspace, we need
to upate the _NET_CURRENT_DESKTOP since the active workspace index

Emit a signal when the window size changes. While it is already
possible to connect to notify::allocation (or width/height), the
new signal is emitted outside a clutter allocation cycle, which
makes it more convenient when adjusting an actor's size/position

As the tile preview is shown or hidden when a window is dragged
around, it may stick around if the drag operation is cancelled.
Make sure that the preview is hidden in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=639988
Drag operations may be cancelled, in which case the dragged window
should be restored to the position/state it had when the drag was
initialized. In order to do this for tiled states, the original

https://bugzilla.gnome.org/show_bug.cgi?id=639988

We want switching between the windows of an application to be an easily

Add code that figures out the key from the XKB geometry and a magic
keysym name "Above_Tab" that refers to this key and switch
the default binding for cycle_group to <Alt>Above_Tab. (This will

GConf until this patch is applied to Metacity as well.)

It may be desirable for theme authors to treat side-by-side tiled
windows differently, for instance to give the edge-touching border
a width of 0, so add additional frame states for tiled windows.

With the existing background functions, single buttons can not be
styled separately - on the left side, the style of the left button
is picked, and the right button's style on the right side.
As theme authors may want to add rounded corners to button groups
as a whole, it makes sense to treat the case of a single button in
a group differently.
https://bugzilla.gnome.org/show_bug.cgi?id=635683
When validating button functions and frame styles, the required
format version of the features used in the theme was compared to
the major version number of the supported format, limiting additions
to major theme format bumps.
Use peek_required_version() instead, so the minor version number
of the supported theme format is taken into account.
https://bugzilla.gnome.org/show_bug.cgi?id=635683
While the configured layout is taken into account for positioning

Commit 2c8c1c6df49 in gtk+ removed gdk_display_get_core_pointer().
The equivalent functionality can be achieved by using the
GdkDeviceManager to retrieve the client pointer device.
Maximized tiled windows end up with an inconsistent tile mode when
unmaximized by other means than dragging the window free (e.g.
using the unmaximize button or double clicking the title bar), so
reset the tile mode when unmaximizing.
This is not a problem for side-by-side tiling, as there are no
alternatives to dragging the window free.
When a tiled window is maximized (e.g. by clicking the title bar
button), unmaximizing the window restores the tiled state. While
this is reasonable for side-by-side tiling, it is confusing for
"maximize" tiled windows, as unmaximization has no visible effect.
Change unmaximize to only restore the tiled state of side-by-side
tiled windows.
The original patch triggered "maximize" when the window was dragged
to the top, so that the pointer was below or on the monitor edge and
above the work area's top.
If there's no chrome at the top of the monitor, so that monitor edge
and work area top fall together, the pointer cannot be moved above
the work area's top, so tiling was not triggered.
GTK is about to clean up its code and remove duplicate macros and
GdkDrawable usage. To prepare for that landing, we use the future-safe
versions of the same calls.

The meta_window_handle_mouse_grab_op_event function ensures
the tile_mode variable is in a consistent state after a drag
op is finished.
The way this is current done is:
if (!window->maximized_vertically &&
window->tile_mode != META_TILE_NONE)
window->tile_mode = META_TILE_NONE;
While valid, it doesn't "read" as well as using the
META_WINDOW_TILED_SIDE_BY_SIDE macro, since the macro is specifically
about side-by-side tiling.
This commit just changes things to use the macro and to not bother
checking the tile mode (since if we just reset it anyway, then it doesn't
matter if the value is right or wrong to begin with).

If we have repeats on for a full-sized image, then if the background

Add code to track and draw the root window background. The advantage of doing
it here as compared to in a plugin is that we can use the visiblity smarts

If handling other than tracking the _XROOTPMAP_ID property is desired in the
future, more functionality like setting the background from a file or doing
cross-fades can be added.
The new background actor is exposed to plugins via meta_plugin_get_background_actor()

For various reasons (mostly the stack tracker correctly predicting the

Fullscreen and maximized windows never have visible shadows - the only
case where we would ever see them is if they bleed onto an adjacent
monitor and that looks bad.
It's small performance win to avoid computing them, and this also avoids
painting the top shadow for all maximized windows in GNOME Shell - since
the top panel isn't a X window, it doesn't factor into the computation
of what parts of windows are visible and maximized windows are computed
as having a top shadow.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
These functions duplicate existing properties; they are added for
convenience and to avoid the GObject property code on some
performance critical painting paths.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Instead of making optimizing obscured shadows an all-or-none operation,
pass the clip region to meta_shadow_paint() and only paint the 9-slices
that are at least partially visible.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Instead of setting shadow parameters on individual windows, add the
idea of a "shadow class". Windows have default shadow classes based
on their frame and window type, which can be overriden by setting
the shadow-class property.
Each shadow class has separably configurable parameters for the
focused and unfocused state. New shadow classes can be defined with
arbitrary names.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Frame types will form the bases of shadow classes, which are strings,
so export the to-string function so that we can do the conversion
uniformly.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
The basic MetaShadowFactory type is moved to a public header, while
the functions to fetch and paint shadows are kept private.
The public object will be used for configuration of shadows by
plugins.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
For attached modal dialogs, we want the shadow to fade out at the top
as if the window was glued to the parent at the top. Add a
shadow-top-fade property to MetaWindowActor and the corresponding
parameter to meta_shadow_factory_get_shadow().
The internal implementation of MetaShadow is adjusted to work
in terms of an "inner border" and "outer border" instead of doing
the calculations in terms of an aggregate border and the spread
of the shadow. The old way of doing things gets clumsy when the
top_fade distance is added in as well.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Add a new frame type META_FRAME_TYPE_ATTACHED which is used for
attached modal dialogs.
The theme format version is bumped to 3.2, and attached windows
can have borders defined in a metacity-theme-3.xml as:
<window version=">= 3.2" type="attached" style_set="[name]"/>
If no style is defined for "attached", drawing will fall back
to the "border" type.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
The current shadow code just uses a single fixed texture (the Gaussian
blur of a rectangle with a fixed blur radius) for drawing all window
shadows. This patch adds the ability
* Implement efficient blurring of arbitrary regions by approximating
a Gaussian blur with multiple box blurs.
* Detect when multiple windows can use the same shadow texture by
converting their shape into a size-invariant MetaWindowShape.
* Add properties shadow-radius, shadow-x-offset, shadow-y-offset,
shadow-opacity to allow the shadow for a window to be configured.
* Add meta_window_actor_paint() and draw the shadow directly
from there rather than using a child actor.
* Remove TidyTextureFrame, which is no longer used

In GTK+ 3, it's mandatory to have a GdkDevice in a synthesized event,
so fill in the pointer device for the events we synthesize and forward
to GTK+. Since gdk_event_set_device() only works for allocated events,
we need to switch to gdk_event_new() rather than using stack allocated
events.
https://bugzilla.gnome.org/show_bug.cgi?id=633401
Now that we create MetaWindow objects for override-redirect windows, we need
to check all key press events to see if they are on GTK+ widgets, not just
events that don't match a MetaWindow. This fixes a problem with alt-Tab stealing
grabs away from the window menu.
https://bugzilla.gnome.org/show_bug.cgi?id=633398
With client side windows, mixing GDK event delivery with explicit calls
to XUngrabPointer() can result in GDK losing button release events
it expects to get. This means that GDK thinks there is an implicit
grab in effect when there is none and send events to the wrong window.
Avoid this by bypassing GDK's event handling for most mouse events.
We do a simplified conversion of the X event into a GdkEvent and send
it to directly to libgtk for delivery.
We make an exception when a GDK grab is already in effect - this is
needed for the correct operation of menus.

While the Meego developers agreed to switching mutter to GTK+-3.0
unconditionally a while ago, Canonical used a GTK+-2.0 build for their

meta_display_process_key_event() always looks up events based on the

XK_Tab).

The code for defining a color as a constant had broken logic: it
would try to parse the color first as an double, then as an integer;
the second attempt would produce an error about overwriting the
already-set-GError. Then it would clear the error and store the constant
as a color.
Use the fact that colors have to start with a letter or #, divide the
space of constants into:
- Integers
- Doubles
- Colors
so we get good error messages. Based on a patch by
William Jon McCann <jmccann@redhat.com>.
Note that this breaks the ability to specify an integer constant as
identical to another integer constant (the same didn't work for doubles.)
I think this was an accidental side effect of the code and not something
that was intentional or people were relying on

In many places, MetaRegion was being used entirely internally, rather
than for gtk2/gtk3 compatibility. In these cases, it's simpler to just
depend on cairo-1.10 (for both gtk2 and gtk3) and use cairo_region_t.
The few places where we did need GDK compatibility (GdkEvent.region and

With the newest changes to GTK3, some things were changed. This patch
now uses the features introduced in gtk3-compat.h in previous patches.
This patch also introduces a macro named USE_GTK3 that is used to
differentiate between GTK3 and GTK2. Its main use is differenting
between expose and draw handlers for GtkWidget subclasses.
The draw vs expose handlers question is usually handled by using ifdefs
at the beginning and end to set up/tear down a cairo_t and then use it.
However, when the function is too different and too many ifdefs would be
necessary, two versions of the function are written. This is currently
the case for:
- MetaAccelLabel
- MetaFrames

Similar to the region compatibility shim, we will soon need a

This commit is in preparation for the work happening in GTK3, which will

For functions (but not callback types), '(closure)' is used on the
callback parameter, and takes the name of the parameter which is
the closure/user data.
A maximized window can't be resized from the screen edges (preserves
Fitts law goodness for the application), but it's still possible
to start a resize drag with alt-middle-button. Currently we just
don't let the user resize the window, while showing drag feedback;
it's more useful to let the user "break" out from the resize.
This provides a fast way to get a window partially aligned with
the screen edges - maximize, then alt-drag it out from one edge.
Behavior choices in this patch:
- You can drag out a window out of maximization in both directions -
smaller and larger. This can be potentilaly useful in multihead.
- Dragging a window in only one direction unmaximizes the window
fully, rather than leaving it in a horizontally/vertically
maximized state. This is done because the horizontally/vertically
maximzed states don't have clear visual representation and can
be confusing to the user.
- If you drag back to the maximized state after breaking out,
maximization is restored, but you can't maximize a window by
dragging to the full size if it didn't start out that way.
A new internal function meta_window_unmaximize_with_gravity() is
added for implementing this; it's a hybrid of
meta_window_unmaximize() and meta_window_resize_with_gravity().

The widget needs to be visible and mapped for GTK3 to deliver expose
events to the widget. This is achieved by making the map function a
no-op and calling gtk_widget_show() instead of just calling
gtk_widget_realize().
Apart from making GTK think the widget is drawable, the effect is the
same.

This way, we can remove the special casing in
meta_frames_paint_to_drawable().

The hacks we were playing by calling gdk_error_trap_push() and then
resetting the error handler are incompatible with the rewrite of
GDK error traps.
Since the new error code has some features that simplify what we
are doing (like automatically figuring out whether a XSync() is needed)
and because our custom error handler didn't have a lot of a point,
use a separate code path for GTK+ 3.0 builds that just uses the
GDK error traps straight-up without a custom error handler.

We don't get correct notifications for the ::cogl-texture property of
ClutterTexture in the case when we are unsetting the pixmap before calling
XFreePixmap. (This is because ClutterX11TexturePixmap is a hack on top
of ClutterTexture and we're a hack on top of that.) So we need to manually
clear everything out.
For consistency we also make sure that we drop all references to dead
textures:
- When the shape changes
- If the window pixmap texture changes without first being cleared
(this is not expected to happen)

Rather than trying to find out from Clutter whether mipmap generation
can be used together with texture_from_pixmap, just always assume
it can't and use the MutterTextureTower emulation code.
This fixes a problem with our previous hack for doing the query
no longer working. In the rare cases where mipmap generation
is supported, it is unlikely to produce significantly more efficient
or better looking results than the emulation. (In terms of efficiency,
we have better knowledge of when we need to update the lower mipmaps
and when we don't than CoglTexturePixmapX11.)
Some care is taken so mutter_shaped_texture_set_create_mipmaps() works
when changed on the fly and properly discards the old mipmap levels.
This isn't necesary currently, since it can only be controlled via
envvar, but is easier than future-proofing through documentation.

A mismerge of the Metacity commit "4943d79 Prevent window self-maximisation"
caused the window's user set size and position to be saved *before*
actually resizing the window to the unmaximized position rather than after.
This meant that after unmaximization the window was in an inconsistent
state and anything that caused a resize to be queued (like a change in
window properties by the application) would cause it to pop back to
the maximized size and position.

In commit d34ae764769 I switched mutter-window to ask for Raw rectangles
from the X server. This avoided 2 non synchronous and 2 synchronous X
requests per window with damage, per frame; 2 (non-sync) to
create/destroy a temporary region to copy the damage region into, 1 to
request the server to copy the damage region into a our given region and
another to fetch that region back into the client. The problem with raw
events though is that it's possible to DOS the compositor with them.
Instead of receiving an event for every bit of damage this patch instead
asks the server to only report BoundingBox changes to the damage region.

This changes the way we handle Damage events so instead of getting an
event when the damage region of a pixmap becomes non-empty we now get
sent all damage rectangles and stream those all though to
ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area()
For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to
clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT
calls are now deferred until just before painting) and since
ClutterGLXTexturePixmap is now capable of queueing clipped redraws that
can result in only updating a sub-region of the stage during a repaint
cycle (and using glXCopySubBufferMESA to present the sub-region redraw
to the front buffer) this should improve performance and reduced power
consumption for a range of use cases. (For example viewing a website
that has animated adverts doesn't force the whole screen to be redrawn
for each frame of the advert)
Besides being able to take advantage of glXCopySubBuffer to only update
a small region of the stage the fact that this patch makes Mutter now
request RawRectangles from the X server means we no longer do a
synchronous X request for a complete Damage Region for every window
damaged each frame. This should also improve performance.
CLUTTER_PAINT=redraws can be used to visualize what parts of the stage
are redrawn and with this patch applied I can open a terminal and as I
type I see that only the damaged areas of the terminal are being
redrawn.
In the case where a mutter window is created for an X Window that is
already mapped then we weren't calling mutter_window_mark_for_repair and
so we weren't calling XCompositeNameWindowPixmap e.g. for menu windows.
This doesn't get noticed because as soon as some damage gets delivered
for such windows the pixmap will be named anyway, but if we were to
change how damage is handled this would result in broken menus.
We now call mutter_window_mark_for_repair in mutter_window_new when the
given Window is already mapped.
It's nice to indicate when a title is truncated with an ellipsis.
Because themes may draw a title multiple times to draw a shadow, or
may include the window icon within the title area, we can't determine
the proper ellipsization width automatically, so add an optional
attribute to the <title/> element "ellipsize_width" which, if set,
is the width to ellipsize at.
This is only enabled if a theme version of 3.1 is required.
When it's not set, we keep the old behavior of just letting the
title be clipped with a hard edge.
https://bugzilla.gnome.org/show_bug.cgi?id=591842
Sometimes you want to position something (usually the title) to be centered
with respect to the entire frame instead of centered with respect to the
individual piece currently being drawn.
This patch adds frame_x_center and frame_y_center variables that represent
the X/Y centers of the frame in the coordinate system of the piece being
drawn.
The theme version is bumped from 3.0 to 3.1 (3.0 is just the new version
system, 3.1 will have all the features we add for Mutter-2.28.)

Although multi-screen support has not been tested and probably
doesn't fully work, the basic setup for multi-screen is that
we have the same list of plugins for all screens, but a different
instance of the plugins for each screen.
To allow plugins to do setup that is screen independent and needs
to occur early in the setup process, we identify a "default plugin
manager" and load (but not start) that plugin manager's plugins
immediately after we know our list of plugins.
That plugin manager is then reused for the first screen we open
and the plugins are started at that time. Separate plugin managers
are loaded and started for any other screens we open.
(A plugin could keep track of whether the screen-independent
setup has been done in a static variable, or it could do everything
in a way that is safe to do repeatedly.)

Allow a plugin to redirect preferences from one GConf location

Overriding is implemented by overwriting the keys in the arrays
of preferences; a list of the current overrides is stored to allow
proper memory management when an override is itself overriden.

This patch cleans up the comments in prefs.c a bit as well; some ideas
about less-exciting potential improvements were removed to make the

Rather than using the plugin objects constructed() method for doing
setup that requires the MetaScreen, add an explicit start() method
that is called after the screen is set.
The reason for this is that this allows plugin objects to be created
early before the bulk of Metacity setup, which then allows plugins
to affect how the setup happens. (For example, to change the way
that preferences are loaded.)
This is an incompatible change, since 'screen' is now not set in the
constructed method, so the plugin API version is bumped.

The current mechanism of metacity-theme-1.xml and metacity-theme-2.xml
is not flexible for allowing small-scale additions. With this patch
we bump the major version version once more to metacity-theme-3.xml
and add a single feature:
Any element in the DTD can have an attribute:
version="[<|<=|=>|>] MAJOR.MINOR"
And it will be ignored unless the predicate is met. (< and > should
be to be entity escaped as < and >)
This allows having alternate sections of the theme file for older and
newer version.
* Required GLib version is bumped to 2.14 so we can parse versions
with a regular expression.
* We switch internal version numbers to be "1000 * major + minor"
* We keep a stack of the maximum required version for the current portion
the XML tree so that the "cannot use versions you don't require" stricture
of the old code can be made local to a subpart of the tree.
* A version on the top metacity_theme element causes the entire file to
be ignored; this allows having one metacity-theme-3.xml for version 3.2
and newer (say) and a metacity-1.xml for everything old.
Actual new features will be added starting with 3.1 - 3.0 is just the
version="" feature.

Simplify code to find the right theme to load and loading it by moving
all the loading code into a load_theme() helper function, and making
meta_load_theme() use that as it searches through the directories.
Look for old-version themes even when loading relative to the working
in debug mode.
Don't unnecessarily duplicate and then free info->theme_file and
info->theme_dir.

The change to using gconf_client_all_entries() in commit 2d57b1b4
meant that workspaces without a GConf key for their name were not
getting a name at all. Fix this by doing a post-processing loop

Since all windows are now MetaWindows as well as compositor
windows, there's no reason to keep a compositor-specific hash table
mapping from XID to MutterWindow.
This reduces complexity and removes a call to XQueryTree that could
potentially produce a BadWindow error if not error-trapped.

meta_compositor_process_event uses meta_error_trap_push/pop for

The change to reduce GConf trips by using
gconf_client_all_entries() broke the fallback to builtin values
because update_binding() was no longer called for bindings not
found in GConf. Fix this by keeping track of the bindings we
find from GConf in a hash table, then looping through and setting
all the bindings at the end.
This also improves efficiency by avoiding a linear scan for each
binding in GConf.
https://bugzilla.gnome.org/show_bug.cgi?id=609710
When we are reading bindings initially, update_list_binding() needs
to be passed the correct "string list type" since we are calling
it with a list of strings instead of a list of GConfValue.

When we are moving a window with a modal dialog to a different
workspace, meta_workspace_focus_default_window() can be called
with 'not_this_one' being the focused modal dialog.
Since the ancestor of that window is also being moved, we must
not focus it as an alternative to the current window; this will
cause windows to be moved back and Metacity to get into an
inconsistent confused state.

We currently allow XRaiseWindow when the same application (defined
by the window group) is focused, but the kind of old applications
that XRaiseWindow are frequently not setting the window group.

When started without session related command line parameters (e.g. from
gnome-session), metacity picks up client_id from the DESKTOP_AUTOSTART_ID
environment variable. Unfortunately, there is no way to distinguish if this was
passed from a config file, representing old saved session, or generated by
gnome-session, therefore load_state is attempted in each case. If the client_id
is generated, there will be no session file, and metacity will report a
warning.
Just remove the warning so that users won't always find a warning at the
start of their .xsession-errors.

Add a configure switch:
--with-libcanberra=[yes/no/auto]
(defaulting to auto); if libcanberra is not found or explicitly
disabled, then the default system bell will be used for the bell
sound and no switch workspace sound is played.
https://bugzilla.gnome.org/show_bug.cgi?id=609585
These sounds are good candidates for caching in the sound server, to
save a bit of CPU and make reaction faster. Hence, tell libcanberra to
cache them.
https://bugzilla.gnome.org/show_bug.cgi?id=609585
libcanberra generates specific tooltip popup sounds and for that
recognizes the tooltip windows by the GtkWindowTypeHint set for them.
This trivial patch simply sets the hint for the self-drawn tooltips
metacity uses.

Right now metacity issues only 1 bell event per second. This is
feels buggy when triggering multiple alarm sounds in a terminal.
This patch simple increases the limit to 1/100ms. 100ms is probably a
good choice since the HIG recommends that all user reaction should
happen within 100ms. With this applied pressing 'Left' in gnome-terminal
feels much more responsive.

metacity tries to do the right thing, by preloading all the relevant
directories before getting the keys one-by-one, but GConfClient isn't actually
smart enough to avoid server roundtrips in this case. That should certainly be
fixed in GConf.
In the meantime, here is a patch that reworks the metacity prefs initialization
to avoid roundtrips for individual keys anyway, by using
gconf_client_all_keys().

The ICE connection is opened by libSM; we can't just close it when
we get an IOError on the ICE connection; instead call SmcCloseConnection()
and mark the connection as closed. This will prevent a segfault if we
exit out of the metacity main loop and get to meta_finalize().

It makes more sense because the grave key is close
to the tab and escape keys which the other cycle
keybindings use.
This always works better for gnome-shell, which
switchings between applications by default with alt-tab.
The user can now alt-tab to the application they want,
and then move their finger to the grave key to select
the window they want.
Windows demanding attention should never appear in the alt-tab list
unless they're of a type which might have appeared there anyway. This
solves a problem under AWN where docks which were marked as demanding
attention appeared in all alt-tab lists; they were irrelevant and it
was impossible to remove them from the lists.

Lines where x1==x2 or y1==y2 may have the second element null. Lines

(This is inspired by Metacity commit 45cbaa2 by Thomas Thurman, but
much simpler - the use of g_date_strftime("%Y") ended up being just
%d for all 90+ current translations)
meta_workspace_set_builtin_struts() is slightly expensive; it involves
discarding all our cached computed information about the layout of the
workspace. So catch calls to set_builtin_struts() that don't change
anything.
https://bugzilla.gnome.org/show_bug.cgi?id=609546
Since meta_workspace_invalidate_work_area() frees the edges
workspace->screen_edges and workspace->monitor_edges, we must clean up
our cached edge resistance data when the invalidate_work_area() is
called on the active workspace, or when the workspace changes.
Make the computation of the edge resistance data lazy so that it
will be recomputed the next time we try to access it.
meta_display_compute_resistance_and_snapping_edges() is made
private to edge-resistance.c
Invaliding the data when active workspace changes also will improve
correctness for edge resistance when the current workspace changes
during a grab operation. (Even with this fix we still don't try to
handle window positions changing during a grab operation; that can't
cause a crash since, unlike screen and monitor edges, the window edges
are freshly allocated, it will just cause slight oddness in that
corner case.)
Root cause tracked down due to much effort by Jon Nettleton.

When putting 32-bit properties into longs on 64-bit architectures,
XGetWindowProperty assumes the values are supposed to be signed, and
so it sign-extends values greater than 0x7fffffff. So if they *aren't*
supposed to be signed, we need to chop off the high bits ourselves.
(Most CARDINAL-valued properties only end up using small values
anyway, so it doesn't matter, but _NET_WM_WINDOW_OPACITY uses the full
range, and so was previously failing on 64-bit machines.)

The CGL_* defines in COGL were always meant to be private and should

Add MutterTextureTower, an abstraction for getting a image with
the right level of detail for rendering at a particular scale,
by manually scaling down by powers of two.
This results in much better looking scaled window images when
mipmaps can't be used with texture_from_pixmap (which is the
typical case for current GL drivers.)
When framebuffer objects are available, they are used to do
the scaledown using the GPU without having to pull the data
back from video memory. A software codepath is also available
for the case when FBO's are not present, though performance
will suffer

The commit that removed metacity-dialog added a global SIGCHLD handler
that caused problems by (a) calling waitpid(-1) and thus breaking
g_child_watch for everyone else, and (b) doing too much from a signal
handler and sometimes causing deadlocks (bug 596200).
This removes the global handler and has each zenity user create its
own child watch to watch for exit. (It also fixes the window class of
the zenity dialogs, so that meta_window_present_delete_dialog() will
work again.)
Having a MetaDisplay::window-demands-attention signal allows to deal with
windows demanding attention in a cetralized fashion.
The signal is emitted when a window is created with initial demands-attention
state and/or when the state changes later on.
Based on original patch by Jon Nettleton.

With the change from bug 582639, we no longer call the reload
functions for properties that are not initially set, so the
initialization of fields in window.c has to match what
window-props.c would set for a missing property.
There was only one discrepancy, window->input, which needs
to be set to TRUE by default (or a window missing a WM_HINTS
property won't get focus); we also add explicit initializers
for a couple of fields that were getting 0-initialized
to the correct default value of FALSE for consistency with
the explicit intialization of the rest of the fields.

For some consumers it's significantly more convenient to be able
to directly connect to a signal on the Window to know when
Mutter is done with it, rather than having to connect to each
Workspace object (and handle workspace additions, etc.).
Similarly, add window-created which acts globally.

When we focus a window on a different desktop, and the calc_showing
idle that hides/shows the windows gets run before we get focus events
back from X, we think that we are hiding the window with the focus
so we focus a "random" window to avoid leaving the user with no focus.
Work around this temporarily by checking display->expected_focus_window;
this isn't a perfect fix because there are cases where
display->expected_focus_window corresponds to a window we tried to
focus in the past but failed, but it makes things work fairly well.

When we create the timeline dummy timeline to ensure that our later
functions that should be run during repaint get called called, pass in
G_MAXUINT to make the duration very long, not 0. (It will get reset
whenever there is no repaint later to run, so the fact that G_MAXUINT
is only ~40 days isn't a problem.)
This fixes a warning from Clutter, but also a real problem.
There was a problem where if, for example, a restack was triggered
out of a clutter event handler, then after Clutter processed the
events, it would proceed immmediately on to repaint the stage without
ever returning control to the GLib main loop. So even though we
had an idle handler installed with a higher priority than the
Clutter stage repainting the clutter stage repainting would happen
first and we'd get a wrong frame.
Fix this by introducing the idea of "later functions", which abstract
the idea of "doing something later" away from g_idle_add() and use
a combination of GLib idle functions and Clutter "repaint functions"
to get our callbacks triggered at the right time, even when they
are installed from a clutter event handler.

This also resolve a FIXME where MUTTER_PRIORITY_BEFORE_REDRAW
could starve stage repainting.
The return value of XGrabKeyboard() wasn't actually being assigned
