This removes our final dependency on Core Events, meaning
we can remove support code for them soon.
This commit is a bit ugly as it requires ui having a dependency on
core, but this is already a hack, so this is thus a hack inside a
hack, and two hacks make a right or however that goes.

In random places that are not grabs, we selected for events on
things like the root window, stage window, COW and more. Switch
these over to using the proper XI2 APIs.

As calling XIGrabDevice multiple times will change it, just

It's unlikely that we'll ever want to support multiple pointer

Mechanically transform the event processing of mutter to care

This removes some duplicate event type checks, and will make
the code cleaner in the future when we want to make the grab_op_event

In order to make the XI2 handling easier on us in the future, we now
split input events from non-input events. This will allow one code path
to use XIEvent, and the other to use XEvent in the future. This commit
has involved plenty of indenting changes, so it's better seen with
git diff -b or &ignorews=1

Since we want nice alt-tab applications for gnome-shell, we should up the
limit to 96. In the future, we probably want to get rid of the icon-cache,
and allow looking up a correctly sized icon directly from the window.
To prevent app breakage, set the legacy WM_HINTS pixmap size directly to
32x32.

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
application-based alt-tab popup, so rather than actually implementing
an application switcher in mutter, let it duplicate the normal window
switcher when run standalone.

Currently meta_display_get_tab_list() will only return windows on

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.
https://bugzilla.gnome.org/show_bug.cgi?id=556696
As the overlay key works differently from normal keybindings, it
requires special treatment. However, by adding a rudimentary
MetaKeyBinding for it, we will be able to confine the special
handling to mutter and treat it like any other keybinding in
the shell.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents
to determine the KeyBindingAction the event would have triggered and
run our own handlers (ugh).
Instead, provide a hook to allow the compositor to filter out keybindings
before processing them normally, regardless of whether the compositor
holds a grab or not.

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
lists 8. Since the work we do on these events is relatively expensive
and we are only really interested in changes to the virtual core
keyboard we can skip other devices' events to cut on needless work.

Using ClutterEffect is not pratical on MetaBackgroundActor, as the FBO
redirection has a noticeable performance impact. Instead, allow adding
GLSL code directly to the pipeline used to draw the background texture.
At the same time, port MetaBackgroundActor to modern Cogl API.

When support for multiple plugins was removed, the logic that was
supposed to send events to Clutter directly *only if there is no filter

Clutter twice if Clutter didn't consume them the first time.

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
fixed, we need to explicitly handle the show-desktop case.

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
replacing the window manager), forcing windows on those workspaces
to the first workspace.
To fix, ignore the preference completely when using dynamic workspaces
and try to restore the previous number of workspaces (as read from
_NET_NUMBER_OF_DESKTOPS).

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
application menu from working properly and are visually expensive
since we now use a very distinct style for unfocused windows.
Instead, delay the actual focus change until the pointer has stopped
moving.

As plugins can now define their own keyboard shortcuts via
meta_display_add_keybinding(), it makes sense for them to

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.
https://bugzilla.gnome.org/show_bug.cgi?id=677116
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.

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
a bit of infrastructure that we would be better off without.
Note that for simplicity, we're keeping the MetaPluginManager, but it only
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

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
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.

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,

Basically we don't really want to create windows that are almost maximized in

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

such cases by ref'ing the windows in the list and checking if they have
