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.

Add meta_window_check_alive(), which is a simple wrapper over
meta_display_ping_window(), and takes care of showing the "Application
is not responding dialog" if needed.
https://bugzilla.gnome.org/show_bug.cgi?id=684340
We want to maintain the invariant that an attached modal dialog is always
of type MODAL_DIALOG, so recompute is_attached_dialog() when the window
type changes.

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
drop the XChangeActivePointerGrab path and just go down the
XIGrabPointer path always.

It's unlikely that we'll ever want to support multiple pointer
devices. Multiple keyboard devices may become useful in the future,
but for now, only care about the core keyboard.

Mechanically transform the event processing of mutter to care
about XI2 events instead of Core Events. Core Events will be left
in the dust soon, and removed entirely.
https://bugzilla.gnome.org/show_bug.cgi?id=688779
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
handler take an XIDeviceEvent directly.
Based on a patch by Owen Taylor <otaylor@fishsoup.net>
https://bugzilla.gnome.org/show_bug.cgi?id=688779
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.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
Currently meta_display_get_tab_list() will only return windows on
a single workspace. Make the workspace parameter optional to allow
requesting windows from all workspaces.

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
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.

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.

If someone plugs in a new monitor, while all their regular windows
should move in absolute X coordinates to ensure they stay on the
same monitor, the desktop window should stay put.

Simplify the set of window-property functions to remove the
unused functions:
meta_window_reload_properties_from_xwindow()
meta_window_reload_properties()
And to make:
meta_window_reload_property()
static. The code is considerably simplified by removing the
plural variants.

Plenty of ugly here, but it works; revert when the zenity version
we depend on stops being bleeding-edge (or we can assume a zenity
version that does not error out on unknown options).
