Do this by duplicating the current code and porting it to use
X again. A better approach would involve our own event structures,
and I really don't want to do that right now. We can clean this up
later.
The grab_window might be NULL, in which case we have a full-screen
grab, but we might still in a grab. Correct the check by asking
whether we're in a grab op or not.
When unmaximizing, we changed bits of window state, then called out
to code that used the frame extents *before* we cleared old cached
extents. Clear the cache up-front as soon as we change the window
state.

In the past, MetaWindowGroup was allocated the size of the screen and
painted the size of the screen because it contained the screen background,
but now we also have the "top window group" which contains only popup
windows, so the allocation doesn't properly reflect the paint bounds
of the window group. Compute the paint bounds accurately from the
children.
https://bugzilla.gnome.org/show_bug.cgi?id=719669
When _GTK_FRAME_EXTENTS changes, we need to redo constraints on
the window - this matters in particular if the toolkit removes
invisible borders when a window is maximized, since otherwise
the maximized window will be positioned as if it still has
invisible borders.

When we have a new client, we potentially set the focus on one of its
surfaces when we map it but the client might not have called
wl_seat.get_keyboard/pointer yet. When it finally calls
get_keyboard/pointer we must then register its resource as the
focus_resource which means that we can only return early if
focus_resource is already set.
https://bugzilla.gnome.org/show_bug.cgi?id=719725
Otherwise clutter events don't have their source actor properly set
and we aren't able to determine the MetaWindow to which a given
keybinding applies.
https://bugzilla.gnome.org/show_bug.cgi?id=719724
Since subsurfaces won't have toplevel MetaWindowActors, we need to
use MetaSurfaceActor instead. These are embedded in the MetaWindowActor,
just like MetaShapedTexture was (in fact, MetaSurfaceActor now contains
a MetaShapedTexture)
Make MetaWindowActor chain up to the generic default MetaCullable
implementation, and remove the helper methods for MetaSurfaceActor
and MetaShapedTexture.
Instead of hardcoded knowledge of certain classes in MetaWindowGroup,
create a generic interface that all actors can implement to get parts of
their regions culled out during redraw, without needing any special
knowledge of how to handle a specific actor.
The names now are a bit suspect. MetaBackgroundGroup is a simple
MetaCullable that knows how to cull children, and MetaWindowGroup is the
"toplevel" cullable that computes the initial two regions. A future
cleanup here could be to merge MetaWindowGroup / MetaBackgroundGroup so
that we only have a generic MetaSimpleCullable, and move the "toplevel"
cullability to be a MetaCullableToplevel.

Somebody could do:
$ mv my-evil-program mutter-wayland
$ PATH=.:$PATH mutter-launch mutter-wayland
It's not secure, and it's hard to test with, so just drop it for now
We'll be relying on logind to hand us permissions in the future.
We require a MetaWindow to properly implement some of the requests
for xdg_surface, so add a way to have an unmapped MetaWindow that
we can store properties on, that we later map when the client
attaches a buffer...
The compiler is not quite smart enough to figure out that the condition
for setting the "compositor" variable matches a later condition for
accessing it, so express this in a way the compiler will understand.
For clarity, rename meta_window_get_outer_rect() to match terminology
we use elsewhere. The old function is left as a deprecated
compatibility wrapper.
Instead of passing around MetaFrameBorders, compute it when we need it.
This also allows us to know that we are using MetaFrameBorders only for windows
with frames (where it is meaningful) and not for frameless windows, which
can have custom borders which we need to interpret differently.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
Cache the computed border size so we can fetch the border size at
any time without worrying that we'll be spending too much time in
the theme code (in some cases we might allocate a PangoFontDescription
or do other significant work.)
The main effort here is clearing the cache when various bits of window
state change that could potentially affect the computed borders.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
There are extensive places in the code where we convert between the client
rectangle and the frame rectangle. Instead of manually doing it use
new helper functions on MetaWindow and the existing meta_window_get_outer_rect().
This fixes a number of bugs where the computation was being done incorrectly,
most of these bugs are with the recently added custom frame extents, but
some relate to invisible borders or even simply to confusion between the
window and frame rectangle.
Switch the placement code to place the frame rectangle rather
than the client window - this simplifies things considerably.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
What we want to achieve is that the dialog is visually centered
on the parent, including the decorations for both, and making sure

Use the "hotplug_mode_update" connector property indicating that the
screen settings should be updated: get a new preferred mode on hotplug
events to handle dynamic guest resizing (where you resize the host
window and the guest resizes with it).
https://bugzilla.gnome.org/show_bug.cgi?id=711216
Clients like on-screen keyboards try not to take focus when the user clicks
on their window by setting the Input hint to false. However, due to GTK+ and
GDK bugs, the public API for setting the Input hint to false don't remove
WM_TAKE_FOCUS from WM_PROTOCOLS, unintentionally putting them into Globally
Active mode.
These clients also expect that since they don't want to take focus, they want
the focus to remain on the existing window. In this case, for clients like
on-screen keyboards, it's so they can send synthesized keyboard events to the
focused window.

Since this is stored in an array full of data that will be copied
around, we can't rely on pointer addresses for every item in a stack
not changing.
I don't see any reason that we even have a weak pointer, either.
This code looks safe to me without it.
When a Wayland compositor, simply rely on the clutter actor allocation
changed signal to sync geometry and emit window actor size changed
signals.
Attaching a wl_buffer to a MetaShapedTexture will signal allocation
changed on the corresponding MetaSurfaceActor, which the MetaWindowActor
is listening to.

Instead of having MetaWindowActor only have one single MetaShapedTexture
as actor drawing its content, introduce a new abstract MetaSurfaceActor
that takes care of drawing.
This is one step in the direction to decouple MetaWaylandSurface with a
MetaWindow and MetaWindowActor (except for shell/xdg surfaces) in order
to finally support subsurfaces like features, or any feature where
window is not drawn using a single texture.
The first step, implemented in this patch, is to not have
MetaWindowActor work directly with a shaped texture. There are still
some cases where it simply gets the texture and goes on as before, but
this should be changed by either removing the need of going via
MetaWindowActor or by adding some generic interface to MetaSurfaceActor
that doesn't limit its functionality to one shaped texture.
There should be no visible difference nor after this patch, but
meta_window_actor_get_texture() and meta_surface_actor_get_texture()
should be deprecated when equivalent functionality has been introduced.

Rather than have MetaWaylandSeat do all the state management itself,
put the split between the root cursor and the window cursor in the
cursor tracker itself. We'll expand this to add a "grab" cursor in
the next commit, allowing us to force a cursor on grab operations.
In order to see all Clutter events, Mutter was previously installing a
signal handler on the ‘captured-event’ signal on the stage and
additionally using a signal emission hook to cope with grabs. This
changes it to use the new clutter_event_add_filter API so that we can
avoid the signal emission hook hack.
There is now a meta_display_handle_event alongside the
meta_display_handle_xevent function which handles events in terms of
Clutter events instead of X events. A Clutter event filter is
registered so that all Clutter events will pass through this function.
The pointer event handling code from the X event version has been moved
into this new function and has been modified to use the details from
the Clutter event instead of the X event. This is a step towards
moving all of the event handling code over to use Clutter events.

This helps with git's diff code by moving all the giant indentation
changes, letting us know what's going on better when we move to
Clutter for event handling.
The plan is to make a new version of meta_display_handle_event that
will accept Clutter events instead of X events and then gradually move
over the events to the new function and finally remove the X version.
When X clients change the keyboard map, the also update a property
on the root window. We can notice that and rebuild our data structures
with the new values, as well as inform the wayland clients.
This is a terrible hack, and it's not how we want to implement things
in 3.12, but it's enough to have the same keyboard layout in the
shell, in X clients and in wayland clients in 3.10, until we decide
on the fate of the keyboard g-s-d plugin.

According to the wayland spec (A.14.1.5. wl_surface::set_opaque_region),
setting a NULL opaque region is possible and should cause the pending
opaque region to be set to empty. This implements the required
behavoir.
Also fixes set_input_region, which suffered from an analogous bug.
Previously the weston-simple-egl demo client caused mutter-wayland to
crash with a segfault in meta_wayland_surface_set_opaque_region, with
this patch it works as intended.

The current time offset calculation is wrong. It is supposed to calculate

Rather than do the cursor -> name translation ourselves in two different
places, use the facilities in libXcursor to do it for us. Put the shared
piece of code in meta-cursor-tracker, and use it for both server-side and
client-side cursor loading.
The destroy notify for a DBus watch holds a reference to the IdleMonitor,
but the IdleMonitorWatch object doesn't (it knows all watches will
be destroyed before the monitor is, so it doesn't need one). This
means that the DBus watch reference can be the only one keeping
the IdleMonitor alive (expecially true for device idle monitors,
which are only used by g-s-d/cursor), and that means that calling
the destroy notify freezes the monitor (and the next X calls
access garbage).

If you maximize a CSD window on a monitor without struts, it ends
up taking the whole monitor size, but it doesn't mean that the

We must set x11_size_changed even if we are frozen, as every window
size change makes the X server drop the pixmap, and we might lose
the information at the next thaw() if the window changes size
twice in one frame (so we would keep drawing with the old pixmap
until something else causes another resize)
Need two passes, because the order we traverse the array is
alphabetical on connector name, not left to right, so we might
see a monitor on the right before we get the offset from disabling
the primary monitor.

No, holes in the framebuffer are not a good a thing: windows can
get lost there, and the user can get very confused.
Instead, compact the monitors that where previously after.

The XSync semantics mandate that alarms already expired will not
fire until the counter is reset and the alarm triggered again, so
clients traditionally called get_idle_time() first to see if they
should install the alarm.
This is inherently racy, as by the time the call is handled by
mutter and the reply received the idle time could be different.
Instead, if we see that the watch would have fired in the past,
fire it immediately.
This is a behavior change, but it's a compatible one, as all legacy
clients are calling get_idle_time() first, and it was perfectly
possible for the idle time counter to trigger the alarm right
after the get_idle_time() call.

Grabs are now slice allocated structures that are handled by
whoever starts the grab. They contain a generic grab structure
with the interface and a backpointer to the MetaWaylandPointer.
The grab interface has been changed to pass full clutter events,
which allowed to remove the confusion between grab->focus and
pointer->focus. Invidual grabs are now required to keep their
focus, and choose whoever gets the events.
https://bugzilla.gnome.org/show_bug.cgi?id=707863
Once the sizing is properly wired up, we need to make sure that
the size at the initial map is correct, and not always 0, 0 because
the buffer is not yet converted into a CoglTexture by MetaShapedTexture,
otherwise we end up sending out configure events at 1 x 1.
To do so, we cache the surface type in the initial state until the
first commit.

To properly resize clients, we need to send them configure events
with the size we computed from the constraint system, and
then check if the new size they ask is compatible with
our expectation.
Note that this does not handle interactive resizing yet, it
merely makes the API calls work for wayland clients.
