In different places we checked the grab op differently when determing
whether we are using _NET_WM_SYNC_REQUEST. This was somewhat covered
up previously by the fact that we only had a sync alarm when using
_NET_WM_SYNC_REQUEST, but that is no longer the case, so consistently
use meta_grab_op_is_resizing() everywhere.

When a client is drawing as hard as possible (without sleeping
between frames) we need to draw as soon possible, since sleeping
will decrease the effective frame rate shown to the user, and
can also result in the system never kicking out of power-saving
mode because it doesn't look fully utilized.
Use the amount the client increments the counter value by when
ending the frame to distinguish these cases:
- Increment by 1: a no-delay frame
- Increment by more than 1: a non-urgent frame, handle normally
https://bugzilla.gnome.org/show_bug.cgi?id=685463
We previously had timestamp information stubbed out in
_NET_WM_FRAME_DRAWN. Instead of this, add a high-resolution timestamp
in _NET_WM_FRAME_DRAWN then send a _NET_WM_FRAME_TIMINGS message
after when we have complete frame timing information, representing
the "presentation time" of the frame as an offset from the timestamp
in _NET_WM_FRAME_DRAWN.
To provide maximum space in the messages,_NET_WM_FRAME_DRAWN and
_NET_WM_FRAME_TIMINGS are not done as WM_PROTOCOLS messages but
have their own message types.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Add a function to convert from g_get_monotonic_time() to a
"high-resolution server timestamp" with microsecond precision.
These timestamps will be used when communicating frame timing
information to the client.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Use XSyncSetPriority() to prioritize the compositor above applications
for X server priority. In practice, this makes little difference because
the Xorg "smart scheduler" will schedule in a single application for
time slices that exceed the frame drawing time, but it's theoretically
right and might make a difference if the X server scheduler is improved.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Using a "sync delay" where we wait for 2 ms after the vblank before
starting to draw the next frame provides for much more predictable
latency for applications. An application can know that if it completes
a frame any time between 8ms before the vblank to the vblank,
it will reliably be drawn on the following vblank period, rather than
having an unpredictable latency depending on whether the compositor
is currently busy drawing a frame or not.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Instead of defining CLUTTER_ENABLE_EXPERIMENTAL_API and
COGL_ENABLE_EXPERIMENTAL_API in individual source files, enable
them on the command line. We weren't tracking exactly what pieces of
experimental API we were using and we were using the experimental
API in most source files that used Clutter and Cogl, so the
local #defines were annoying rather than useful.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
It's possible that a client might update the (extended)
_NET_WM_SYNC_REQUEST_COUNTER counter twice without actually drawing
anything. In that case, we still should send a _NET_WM_FRAME_DRAWN
message since it's hard for a client to know every case in which
no damage is generated. For now, do it the easy way by forcing a
stage repaint.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Resizing the frame triggers creation of a new backing pixmap for the
window, so we should do that first before we resize the client window
and mess up the contents of the old backing pixmap.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
When the application provides the extended second counter for
_NET_WM_SYNC_REQUEST, send a client message with completion
information after the next redraw after each counter update
by the application.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
If an application provides two values in _NET_WM_SYNC_REQUEST_COUNTER,
use that as a signal that the applications wants an extended behavior
where it can update the counter as well as the window manager. If the
application updates the counter to an odd value, updates of the
window are frozen until the counter is updated again to an even value.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Instead of creating a new alarm each time we resize a window
interactively, create an alarm the first time we resize a window
and keep it around permanently until we unmanage the window.
Doing it this way will be useful when we allow the application to
spontaneously generate sync request updates to indicate
frames it is drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Replace the unused meta_compositor_set_updates() with
a reversed-meaning meta_compositor_set_updates_frozen(), and use
it to implement freezing application window updates during
interactive resizing. This avoids drawing new areas of the window
with blank content before the application has a chance to repaint.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
meta_screen_resize calls meta_window_update_for_monitors_changed for all
windows including OR windows when the monitors change (or screen size).
This calls meta_window_move_between_rects for the window which attempts to
move the OR window by calling meta_window_move_resize.
meta_window_move_resize refuses to do anything on OR windows (just returns
for OR windows).
This causes a storm of assert messages when the screen
resolution changes while an OR window is visible.
(like the one gnome-control-center displays with the monitor name).
Fix that by not calling meta_window_update_for_monitors_changed for OR windows
and let the applications handle them by themselves.

- set GTK_STYLE_CLASS_TOOLTIP on the window, and use the same code of
GtkTooltip to paint it
- set GDK_WINDOW_TYPE_HINT_TOOLTIP and make the window non-resizable, so
it doesn't get an incorrect shadow from the WM
https://bugzilla.gnome.org/show_bug.cgi?id=692741
Since we're going to use the tooltip's rounded corners we need a little
bit more of margin (which wasn't a bad idea even with the frame).
Also, don't use GtkMisc for this anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=692741
As the hash table no longer stores only window IDs, we should rename it so

XInput 2.3 adds support for "barrier events", which let us know when
a pointer barrier has been hit, and when the pointer has stopped
hitting the barrier, and lets us "release" the barrier, temporarily
letting the pointer pass through the barrier. These features can be
combined to allow for certain pointer gestures, such as "pushing"
against the bottom of the screen, or stopping the pointer on monitor
edges while dragging slowly for increased edge precision.
This commit should allow graceful fallback if servers with
XInput 2.3 aren't supported.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
Currently, we have a few function wrappers in the shell for pointer
barriers. If we want to implement interactive features on barriers,
we need some sort of signal to be notified of the interactivity.
In that case, we need to make a more sophisticated object-based wrapper
for a pointer barrier. Add one, and stick it in mutter.

Some windows may already have event masks on them that we've selected

gdk_device_manager_get_client_pointer which in calls

This new hint allows compositors to know what portions of a window
will be obscured, as a region above them is opaque. For an RGB window,
possible to glean this information from the bounding shape region of
a client window, but not for an ARGB32 window. This new hint allows
clients that use ARGB32 windows to say which part of the window is
opaque, allowing this sort of optimization.

Currently we only unredirect monitor sized override redirect windows.
This was supposed to catch fullscreen opengl games and improve
their performance.
Newer games like fullscreen webgl games and SDL2 using games (like L4D) as well as wine based games do not use override redirect windows so we need a better
heuristic to catch them.
GLX windows always damage the whole window when calling glxSwapBuffers and
never damage sub regions. So we can use that to detect them.
The new heuristic unredirects windows fullscreen windows that have damaged the
whole window more then 100 times in a row.

GtkWindow added the BACKGROUND style class to all windows, which the

The minimize action does not make much sense without a window list,
which is why its default keybinding was removed in bug 643609;

not imply a window list. We will then assign a default shortcut again.

MetaButtonLayout is extremely unfriendly for introspection: its fields
are arrays of a fixed length, but the actual length is determined by
a custom stop value (e.g. not NULL / 0).
Without API changes this will never work nicely in introspection, but

the stop value rather than leaving it at random values.

Currently, we ping windows only when attempting to delete them, but
if the application is not responding, we want to show the dialog
as soon as possible. Given that we cannot be passively notified that
the window stopped responding with the current X11 protocol, a good
workaround is to ping the window when activating it.
If the window stops responding while active, it is expected the user
will try to switch window or open the overview, and when coming back
he'll get the failure dialog.

Since we want nice alt-tab applications for gnome-shell, we should up the

Add an additional "switcher" keybinding for switching between
applications rather than windows (like the existing 'switch-windows'
and 'switch-group' bindings).
The purpose of the new keybinding is to be taken over by gnome-shell's

an application switcher in mutter, let it duplicate the normal window
switcher when run standalone.

The window positioning is delayed in idle_move_resize() in case the application
resizes/maximizes its window quickly after its creation. The delayed
positioning uses window->user_rect because of bug 426519 comment 3 (see
meta_window_move_resize_now()).
user_rect was not set in the initial positioning, causing the delayed
positioning unable to know which monitor we use for this window. As a
consequence, the window could jump spontaneously from one monitor to another.
With this patch, the window does not jump anymore.

As the overlay key works differently from normal keybindings, it
requires special treatment. However, by adding a rudimentary

Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents

before processing them normally, regardless of whether the compositor

The X server sends a XkbNewKeyboardNotify event for each keyboard
device when a new keyboard description is loaded. These days a typical
computer has several keyboard devices, e.g. xinput on this laptop

and we are only really interested in changes to the virtual core
keyboard we can skip other devices' events to cut on needless work.

When using the show-desktop shortcut with no desktop window, unshowing
will focus the second-most-recently-used window. If we find a desktop
window, it will be focused explicitly and everything works as expected;
however without a desktop window, we end up hiding the focus window,
which will use focus_default_window() with the not_this_one parameter
to move focus away. We used to get away with this, as the not_this_one
parameter was ignored until commit e257580b94, now with bug 675982

On startup, workspaces are initialized according to the num-workspaces
preference. However when using dynamic workspaces, the actual number
of workspaces in use might be greater than the preference (when

To fix, ignore the preference completely when using dynamic workspaces
and try to restore the previous number of workspaces (as read from

Fixes bug #670396. Without this fix the guard window may not
extend over the whole area of the screen after a XRandR
reconfiguration. The effect being that mouse events are
delivered to invisible windows.
Moving focus immediately on crossing events as we currently do
in focus-follows-mouse mode may trigger a lot of unwanted focus
changes when moving over unrelated windows on the way to a target.
Those accidental focus changes prevent features like GNOME Shell's

since we now use a very distinct style for unfocused windows.
Instead, delay the actual focus change until the pointer has stopped

meta_window_group_paint tries to carefully figure out which parts of the

When changing the overlay-key setting, the change only takes effect
on restart - there are actually two bugs involved:
(1) the test whether the key has changed is located in the
else part of a test for string settings (and overlay-key happens
to be a string settings ...)
(2) with (1) fixed, a change signal is emitted, which triggers a
reload of all keybindings - unfortunately, the actual value
of overlay-key is only read on startup, so the key is reloaded
using the old value
Fix both issues by replacing the custom handling of the overlay-key

Since we now cache windows in the X server, we don't really need to cache
them here. Since we are redirecting windows in most cases, we're not gaining
anything except added memory usage. Additionally, remove the clip to screen
optimization - if a window is partially off-screen, we still need to draw
the entire thing as redirection means we won't get an expose event for it.
Additionally, when introducing invisible borders, something accidentally
slipped through: we were getting expose events on the invisible borders,
and they weren't in the cached pixels rect, so we were painting the theme
for them, even if we didn't actually paint anything with cairo. Make sure
to clip out the invisible borders instead of just the client rect so that
we don't draw if our expose event is on the invisible borders.

The EXPORT_PACKAGES variable to the GIR makefile should be the

meta_window_actor_has_shadow() is called for every paint for every

All animations use the constants directly, so this is just declaring

Require the headers for "XFree86" Xinerama to be present at compile
time. The older "Solaris" Xinerama is only needed for versions of
Solaris where Mutter is unlikely to work. Solaris 10 and 11 include

that will actually work for Solaris 11, which uses Xorg.

Cogl now has public experimental API to create a rectangle texture
which we can use instead of creating a foreign texture with GL. This
avoids Mutter depending on Cogl including a GL header from its public
headers which it might not do in future.
https://bugzilla.gnome.org/show_bug.cgi?id=672711
Since Cogl doesn't support multi-texturing with sliced textures and the
shape texture is combined with the texture-from-pixmap texture we need
to make sure we never construct a sliced mask texture. This patch simply
passes the COGL_TEXTURE_NO_SLICE flag to cogl_texture_from_data when
creating the shape mask texture.

Currently pressing the overlay key only triggers the overview if
no other key is pressed between KeyPress and KeyRelease. Extend

Starting the auto-maximize process on a window like a
META_WINDOW_DESKTOP window that is not maximizable gets placement into
a confused state and eventually results in the window being positioned
at the wrong position (the position that an auto-maximized window would
be restored to.)
https://bugzilla.gnome.org/show_bug.cgi?id=673566
When mutter recognizes a full-screen window, it tries to raise it to the top
of the stack. Unfortunately, a recent rewrite of the stack code didn't do
well with raising a window to the top of the stack if the stack wasn't in
a consistent state -- it would crash. Ensure that the stack is in a consistent
state at the top of meta_stack_raise/meta_stack_lower.
https://bugzilla.redhat.com/show_bug.cgi?id=806437https://bugzilla.gnome.org/show_bug.cgi?id=672797
Commit 2fc880db switched from focusing the topmost window as the default
window to focusing the MRU window. This was done in alignment with the
introduction of per-workspace MRU lists to avoid problems where the window
stack was inadvertently changed when focusing windows during window switches.
Now that focusing windows don't have as big an impact on the stacking order,
we can revert back to focusing the top window, which is less confusing to the
user.
For now, leave per-workspace MRU lists, as they're a pretty good approximation
of a global MRU list, and it works well enough.

"warning: 'match_tile_mode' may be used uninitialized in this function", it
complains. It thinks it's not unused because of other values of
window->tile_mode, but other complex logic ensures that it can't be
META_TILE_MAXIMIZED, so this is a safe commit.
Windows that have minimum widths larger than the screen can't be maximized,
even though we put them in a maximized state and allow users to do so:
the window just won't change size and position. Fix this by simply not giving
the option to maximize, like what happens for non-resizable windows.
https://bugzilla.gnome.org/show_bug.cgi?id=643606
A lot of code did something similar to:
MetaFrameBorders borders;
if (window->frame)
meta_frame_calc_borders (window->frame, &borders);
else
meta_frame_borders_clear (&borders);
Sometimes, the else part was omitted and we were unknowingly using
uninitalized values for OR windows. Clean this up by just testing
for a NULL frame in meta_frame_calc_borders and clearing for the
caller if so.
https://bugzilla.gnome.org/show_bug.cgi?id=643606
Since we're going to be evaluating the work area at startup now, we need

After the changes in style handling in GTK+, mutter's tooltips no

Windows that start up in a size that is almost as big as the workarea create
extra work for the user (resizing or maximizing) so save the user's time by
detecting such windows and automaximize them.
https://bugzilla.gnome.org/show_bug.cgi?id=671677
Basically we don't really want to create windows that are almost maximized in
size but not actually maximized. This creates work for the user and makes it
very difficult to use and resize manually.
So set the newly unmaximized window size to the previously used size or 80% of the
size of the current workarea (attempting to retain natural aspect ratio if
possible), whichever is smaller.

Some modifiers like NumLock and ScrollLock don't make sense in
keybindings, which is why we ignore them when matching keybindings

The move-to-corner keybindings weren't treated as user actions, which
resulted in them not affecting the saved position - they weren't

down by Mariusz Libera.

We currently sync the number of workspaces with the corresponding
preference. This is not really useful with GNOME Shell's dynamic
handling of workspaces, not least as the setting is effectively
ignored. Worse, it will trigger writes to dconf on login, slowing
down startup, so add a setting to indicate that workspaces are managed
dynamically and really ignore the num-workspaces setting when set.

After _unmanage the object is semantically dead even if technically it's not,
so remove the prefs listener here to prevent it being called for a dead

In particular this fixes a crash when starting up gnome-shell with at least
one gimp utility window opened which causes mutter to create a MetaWindow for

unmanage the MetaWindow. Afterwards prefs_changed_callback is called for this
dead MetaWindow and tries to dereference the window->monitor pointer which is
already NULL.

The experimental Cogl api cogl_texture_pixmap_new() was recently changed
so it now expects an explicit CoglContext argument and it can also
return exceptions now via a GError. This patch updates mutters use of
the api accordingly.
This was preventing Clutter from running its dispose, preventing
it from being destroyed correctly. While a major bug and possibly
big memory leak, the most obvious effect was the message that Clutter
spat out:
Clutter-CRITICAL **: clutter_actor_iter_next: assertion `ri->age == ri->root->priv->age' failed
Since we never disposed the actor correctly, it was never removed
from its parent, and the age wasn't updated correctly.
When we were shaping the window with a cairo region, there was an easy
optimization to restrict painting only to the pixels we were going to
actually draw. With rounded corners, the amount of work we have to do
figure out what pixels isn't worth the small savings of not drawing the
completely transparent parts of the corners, so remove this optimization,
and the supporting meta_shaped_texture_get_visible_pixels_region()
https://bugzilla.gnome.org/show_bug.cgi?id=657639
ClutterTexture has many features that we simply don't use and don't make
sense for a subclass with custom drawing. Deriving directly from ClutterActor
simplifies our code by avoiding workarounds and makes things more robust.
Additionally, make it public. GNOME Shell was already assuming that any
MetaShapedTexture was also a ClutterTexture, and we need to replace these
bits with new API for GNOME Shell to use.

When meta_display_unmanage_window_for_screen() is called, it gets a list
of windows and iterates over them and unmanages them, but unmanaging a
window with attached modal dialogs also unmanages those attached modal
dialogs (in the normal case, temporarily), so we need to guard against
such cases by ref'ing the windows in the list and checking if they have
already been unmanaged.

If we get two configure events on the root window in close
sequence, then we could get the sequence:
ConfigureNotify on the root window w1xh1
Processed by Mutter
clutter_actor_set_size(stage, w1, h1)
<relayout happens, stage window resized by clutter>
ConfigureNotify on the root window, w2xh2
Processed by Mutter
clutter_actor_set_size(stage, w2, h2)
ConfigureNotify on the stage window, w1, h1)
Processed by Clutter
clutter_actor_set_size(stage, w1, h1)
<relayout happens, stage window resized by clutter>
Leaving the stage at the wrong size. To avoid fighting with Clutter,
switch to resizing the stage with XResizeWindow(), similar to how a
toplevel window is handled by a window manager.
For maximized windows, titlebars cannot be used to reposition or
scale the window, so if an application does not use it to convey
useful information (other than the application name), the screen
space occupied by titlebars could be put to better use.
To account for this use case, a setting for requesting that windows'
titlebars should be hidden during maximization has been added to
GTK+, add support for this in the window manager.

The current code requires windows to be resizable to be considered
for tiling, which excludes all maximized/tiled windows. While this
restriction concurs with the desired behavior for edge-tiling, it
feels overly restrictive for keybindings.
As the edge-tiling code in update_move() already ensures the above
restriction, it seems save to remove it from the can_tile_maximized()
function, assuming that windows that are not meant to be tiled or
maximized won't provide a maximize function.

The code here was always incorrect - we were processing damage events for
windows without having a texture. Before, this didn't matter, as
cogl_texture_get_width silently returned 0 for invalid handles. Cogl commit
4c3dadd35e changed this.
The fix here involves two strategies. First, we try to guard MetaTextureTower
from invalid textures. Second, we try not to go down the path that eventually
calls meta_shaped_texture_update_area by not handling damage events if we
don't have a texture for the window.

meta_window_get_current_tile_area() computes the area where the tiled window
should be based on the current pointer position but that's only meaningful
when the user is actually dragging the window.
When running the tiling constrain the pointer might be on other monitor and at
that point the window jumps to this other monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642580
When using more than one monitor, tiled maximization can be triggered with the
pointer in one monitor while most of the window area remains in another. This

When a window loses its frame we must unset any overlay path previously set on

Shaded windows are assumed to be reduced to the titlebar: the
current code enforces a visible bottom border of 0 and only takes
the size of the title bar (+ invisible top border) into account
when resizing the frame. However, we still add an invisible border

Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.
Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).
Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new

would affect new dialogs, but not existing ones.

The code here was wrong in every way: it only updated the shape if all the

and the bounding rectangle's x and y positions were still important otherwise.
This had user-visible impact when doing simple things like changing the
border_width. It would short-circuit here and due to the above incorrectness,
weirdness could happen where windows would be cut off and so on.

There were actually *two* MetaFrameGeometry structs: one in theme-private.h,

Remove the public struct, replace it with MetaFrameBorders and scrap all
the pointer hacks to populate it, instead relying on both structs being used

Since we're not setting the frame's output shape any more, it doesn't
make sense to calculate the output shape based on the frame window.
Instead, track the client window directly and calculate the output shape
based on that.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
In preparation for switching to handling the output shape purely by what we
paint, stop applying a shape to the frame of the window. Even when we restore
handling the output shape, this will change the behavior with respect to input;
transparent areas between the frame and the contents will stop clicks rather

MetaShapedTexture can be a ClutterX11TexturePixmap sub-class, given that
ClutterGLXTexturePixmap is just a shim compatibility layer since Clutter
1.4, and it's been deprecated.
https://bugzilla.gnome.org/show_bug.cgi?id=655064
meta-texture-rectangle and meta-shaped-texture both create textures
with GL_TEXTURE_RECTANGLE_ARB as the target using direct GL
calls. This patch moves that code into a shared utility function in a
separate file instead. The function resolves the required GL symbols
dynamically instead of linking to them directly so that if Clutter
eventually stops linking to -lGL mutter will continue to build. The
function also splits the texture creation into a separate texture
creation and data upload stage so that it can use
cogl_texture_set_region to upload the data. That way it can avoid
clobbering the glPixelStore state and it can let Cogl do any necessary
format conversion. The code preserves the old value of the rectangle
texture binding instead of clobbering it because Cogl expects to be
able to cache this value to avoid redundant glBindTexture
calls. Finally, the function uses cogl_object_set_data to
automatically destroy the GL texture when the Cogl texture is
destroyed. This avoids having to have special code to destroy the cogl
texture.
https://bugzilla.gnome.org/show_bug.cgi?id=654569
texture_tower_revalidate_fbo() called cogl_flush() to work around
clutter bug #2110, which has been long fixed.
As we depend on clutter 1.7.x anyway we can just remove that workaround.
https://bugzilla.gnome.org/show_bug.cgi?id=654729
Clutter now has some API to get the bounds of the current redraw clip
so Mutter no longer needs to make direct GL calls to get the scissor
rect. This should make it more robust against Cogl or Clutter changing
how it does the clipping.

Calling meta_later_add() or meta_later_remove() from within a
META_LATER_BEFORE_REDRAW callback ended up being a no-op, because of
how run_repaint_laters() was fiddling with the laters list. (This
resulted in a crash in window.c:idle_calc_repaint(), which assumed it
would only be called when a certain queue was non-empty, but was
getting called anyway because of a failed meta_later_remove() call.)
Fix this by having run_repaint_laters() work on a copy of the laters
list instead, and add refcounting to MetaLater so that removing a
later that run_repaint_laters() hasn't gotten to yet won't cause
problems.

When we get a press of the overlay key, and then another key is pressed,
first try to handle the combination as a global keybinding. If that fails,
call XAllowEvents(..., ReplayKeyboard, ...) to let it be handled by

This requires restructuring things to call XAllowEvents a bit later
so we can pass the right mode.

meta_frames_destroy() was not safe to be called multiple times, which

The code assumed that the focus window was always the one at the
top of the window stack, which is not true if an unfocused window
has the above hint set.
Rather than fixing this assumption, rename the function to
lower_beneath_grab_window() and use the display's grab window - the
function is only used for displaying the tile previews, which means
that we want the grab window anyway.

Add an additional color type to pick up colors defined with
@define-color in the GTK+ theme's CSS:
gtk:custom(name,fallback)
(where "name" refers to the name defined in GTK+'s CSS, and fallback
refers to an alternative color spec which is used when the color
referenced by "name" is not found)
The main intent of the change is to allow designers to improve
Adwaita's dark theme variant without having to compromise on colors
which work in the light variant as well.

This patch fixes an issue encountered when building mutter

We now use GtkStyleContext exclusively, so it's a bit weird to store

GdkColor is about to be deprecated, so move to GdkRGBA instead.

When detaching/attaching a dialog, we were only updating
appears-focused on the parent if the child itself was focused, but in
fact, we need to do it if the child has an attached child which is
focused too.
To simplify the case of detaching a focused subtree from its parent,
we change meta_window_propagate_focus_appearance() to use
@window->display->focus_window as the window to add/remove as the
attached_focus_window, and @window only as the starting point to
propagate from. That way we can propagate focus-removal up to
@window's (soon-to-be-ex-)ancestors without having to remove it from
its descendants as well.

Don't set a window's xtransient_for if it would create a loop. Since

When there was no root background pixmap, we were using a 1x1 repeating
texture as a simple way of drawing a solid color without adding a
second code path. However, when that 1x1 texture was combined into
a larger "atlas texture", hardware repeat couldn't be used, so a
small inefficiency from this approach became an enormous inefficiency
as clutter drew every pixel of the background as a separate rectangle.

When left-clicking the frame border with the titlebar being
off-screen, rather than starting the expected grab operation the
window menu was popped up.

way to get to the window menu.

meta_run() calls meta_finalize() after the main loop exits, which ends
up calling meta_display_close(), which calls
meta_quit(META_EXIT_SUCCESS), meaning that any exit status passed to

longer running.

Like the setting of new frames' background is delayed until the
frame is associated with its window, delay attaching the initial
style, so that the correct style variant is picked.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
When the _GTK_THEME_VARIANT property changes, rather than just
updating the window's theme_variant property, update its frame
style as well, so that the window decoration reflects the requested
variant. As the initial properties of a window may be read before
its frame is created, there will be cases where the change is not
picked up initially.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
In order to pick up colors from a GtkStyleContext, a temporary
GtkStyle object was created from the context and destroyed after
copying the requested GdkColor. This is slightly inefficient, so
get the appropriate GdkRGBA from the context and translate it to
a GdkColor, based on the compatibility code in gtkstyle.c.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
Rather than sharing a single style context between all frames, use
a default style and one style per encountered variant (as determined
by the _GTK_THEME_VARIANT property), so that colors from the GTK+ style
are picked from the correct theme variant.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
Since version 3.0, GTK+ has support for style variants. At the moment,
themes may provide a dark variant, which can be requested by
applications via GtkSettings. The requested variant is exported to
X11 via the _GTK_THEME_VARIANT property - support this property, in
order to pick up the correct style variant in the future.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
Rather than using a single widget's style for GTK+ colors in themes,
use the style context parameter of the drawing functions for those
colors. Right now, a single style context is shared between frames,
but this will change to support different style variants.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
To determine the correct background style, the UI needs to access
some frame properties via meta_core_get(); this call will bail out

If a window is not maximizable, then that probably means it looks dumb

If a window had no title property set, then the

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,

converted to the locale encoding with a UTF-8 message.

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

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.

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

well if necessary.

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

As the position of attached modal dialogs is determined entirely

Commit 96c43866 changed the tiling behavior to prefer edge tiling
over maximization in corner cases (well, quite literally). As a

the new behavior for untiled windows.
