meta_window_group_paint tries to carefully figure out which parts of the
scene it can avoid painting. One area it avoids painting is the region of
the screen occupied by an unredirected window (if there's one present).
When subtracting from the visible region, it gets the coordinate spaces
confused, and ends up subtracting the area at the wrong offset. Fix this
by translating the rectangle subtracted from the visible region.

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
with the regular handling of string preferences.

When we consider tiling a special case of maximization, it makes

Currently we decide whether a modal dialog should be attached or not
when mapping it, i.e. we don't pick up preference changes that happen

extra polish ...

If a window has its BoundingRegion shaped, we shouldn't unredirect it,

The "multiple plugins loaded at once" strategy was always a big fiction:
while it may be viable if you're super careful, it's fragile and requires

manages one plugin. A possible future cleanup would be to remove it entirely.

This effectively makes MetaShapedTexture not a MetaShapedTexture, but a simple
and dumb MetaMaskedTexture, with an optimization for clipped regions.
We're doing this as the mask may need to be more complicated than made of
a cairo path -- we eventually want GTK+ to draw the entire frame background,
which we'll then scan.
https://bugzilla.gnome.org/show_bug.cgi?id=676052
As we want GTK+ to paint the mask on an A8, we can't simply use a cairo
path. A later commit will make this into a simple masked texture, and
meta-window-actor will be in control of the mask.

The concept of a clip region doesn't make sense now that we have anti-aliased

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.

Starting the auto-maximize process on a window like a

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

state at the top of meta_stack_raise/meta_stack_lower.

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.

Windows that have minimum widths larger than the screen can't be maximized,

We currently sync the number of workspaces with the corresponding

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()

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

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

such cases by ref'ing the windows in the list and checking if they have
already been unmanaged.

ConfigureNotify on the root window, w2xh2

ConfigureNotify on the stage window, w1, h1)

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

cogl_texture_get_width silently returned 0 for invalid handles. Cogl commit

meta_window_get_current_tile_area() computes the area where the tiled window

When using more than one monitor, tiled maximization can be triggered with the

border and just interfere with the parent dialog.
This requires changing a bit of API to help identify the type of dialog.

Our usage of DamageReportBoundingBox was causing us to miss some
updates when an area of the screen was drawn twice in rapid
succession. Add an explicit XSync() call to force the server
to flush rendering to the kernel before we draw.

If XRANDR is availible, we track the first (or primary) output per
crtc (== xinerama monitor) so when the monitors change we can try
to find the same output and move windows there. If we can't find the
original monitor in the new set (or XRANDR is not supported) we move
the window to the primary monitor.

The ignored_serials member of Display refers explicitly to crossing
serials - rename the member and associated functions and constants
for clarity.
https://bugzilla.gnome.org/show_bug.cgi?id=597190
* Export meta_display_add_ignored_crossing_serial()
* Add the serial for reshaping the stage
* Increase the size of the "ignored_serials" array a bit to
try to avoid the possibility of losing serials from multiple
reshapes happening close together.

This goes better with the general style of similar alerts throughout
GNOME 3, and as has been pointed out in bug 591735, 'Mutter' is
a somewhat unfortunate title in several lanuages, such as English
and German.
* At least one line (possibly blank) is required after a function name for a doc header
to be parsed correctly.
* SnStartupSequence isn't a type known to introspection
Some apps that do a lot of rendering on the screen like games, mostly run in
fullscreen where there is no need for them to be redirected doing so does add
an overhead; while performance is critical for those apps.
This can be disabled / enabled at runtime using
meta_enable_unredirect_for_screen / meta_disable_unredirect_for_screen

Instead of requiring a singleton MetaBackgroundActor for the screen,
allow creating multiple copies that internally share a single
CoglTexture behind the scenes. This will be useful for allowing
multiple views of the screen background with different rendering
options.

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
behavior with this patch would be that changing the gconf setting
would affect new dialogs, but not existing ones.

The code here was wrong in every way: it only updated the shape if all the
borders changed. It never saved new last_borders even if it *had* changed,
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.

gtk:custom() requires a fallback color in case the GTK+ theme in use
does not define the desired color. As in general the fallback color
will approximate the intended color, there is the risk of typos going
unnoticed. To make catching these kind of errors easier, allow to ignore
the fallback color specified (and fall back to a nice shade of pink
instead) by setting an environment variable.

get_outer_rect now returns the visible region, and a new get_input_rect
method returns the boundaries of the full frame, including the possible
invisible regions. When undecorated, both do the samething.
