Commit 47131b1d ("frames: Handle touch events") introduced an assert to
make sure that all mouse button actions are handled in mutter.
However, mice can have a more than 5 buttons, so simply ignore the
"other" actions instead of aborting.

Compositor effects change the actor size and position, which can lead to
inconsistent output enter/leave notifications, leaving clients' surfaces
without any output set.
Update output enter/leave notifications after all compositor effects are
completed so that we give clients accurate output location.

When using plugins, the effects will affect the MetaWindowActor size

Add a new signal "effects-completed" wired to the corresponding

derived objects can be notified when all effects are completed and use
the actual size and position.

After 20176d03, the Wayland backend only synchronizes with the
compositor after a geometry was set, and it was different from
the current geometry.
That commit was mistakenly comparing the geometry before chaining
up, which would yield a false negative on the case where the
client didn't call set_geometry() before commit().
Fix that by caching the old geometry locally, chain up (and thus
apply the new geometry rectangle), then comparing the old and
current geometry rectangles.

This is just done on wayland as it'll break horribly on X11, we let
this happen through pointer emulated events in XISelectEvents evmask
instead.
Some things had to be made slightly more generic to accomodate touch
events. The MetaFrames shall lock onto a single touch at a time, we
don't allow crazy stuff like multi-window drag nor multi-edge resizes.

When using two monitors size by side with different scales, once the
cursor moves from one output to another one, its size changes based on
the scale of the given output.
Changing the size of the cursor can cause the cursor area to change
output again if the hotspot is not exactly at the top left corner of the
area, causing the texture of the cursor to change, which will trigger
another output change, so on and so forth causing continuous surface
enter/leave event which flood the clients and eventually kill them.
Change the logic to use only the actual cursor position to determine if
its on the given logical monitor, so that it remains immune to scale
changes induced by output scale differences.

We require logind for the native backend, but the backend itself is
optional. However since commit 06c357d78, we will always throw an
error if neither logind nor elogind are available, even when the
backend is disabled.
As we still support "auto" - that is, whether the native backend is
enabled depends on whether its dependencies are available - the
easiest option is to make sure we always include either elogind or
libsystemd in the dependency check rather than erring out explicitly
if neither is found.

(cherry picked from commit 82564772dc)
The current implementation of the XdgSurface v6 protocol does not check
if the window changed before calling meta_window_wayland_move_resize().
The problem with this approach is that calling this function is a costly
operation since we enter the compositor side. In GNOME Shell case, it is
in JavaScript, which triggers a GJS trampoline. Calling this function on
every mouse movement is naturally as terrible as it could be - and is
exactly what happens now.
This commit adds the necessary checks to only call move_resize() when
the window actually changed, or when it needs to be updated.
https://bugzilla.gnome.org/show_bug.cgi?id=780292
Issue: #78
This will be used by the next commit to determine when a window
geometry change should be ignored or not. Normally, it would be
enough to just check if the position and sizes changed.
The position, in this case, is relative to the client buffer, not
the global position. But because it is not global, there is one,
admitedly unlikely, situation where the window state is updated
while the client size and relative positions don't change.
One can trigger this by e.g. tiling the window to the half-left of
the monitor, then immediately tile it to half-right. In this case,
the window didn't change, just it's state, but nonetheless we need
to notify the compositor and run the full move/resize routines.
When that case happens, though, the MetaWindowWayland is tracking
the pending state change or a move. And this is what we need to
expose.

Issue: #78
In the old, synchronous X.org world, we could assume that
a state change always meant a synchronizing the window
geometry right after. After firing an operation that
would change the window state, such as maximizing or
tiling the window,
With Wayland, however, this is not valid anymore, since
Wayland is asynchronous. In this scenario, we call
meta_window_move_resize_internal() twice: when the user
executes an state-changing operation, and when the server
ACKs this operation. This breaks the previous assumptions,
and as a consequence, it breaks the GNOME Shell animations
in Wayland.
The solution is giving the MetaWindow control over the time
when the window geometry is synchronized with the compositor.
That is done by introducing a new result flag. Wayland asks
for a compositor sync after receiving an ACK from the server,
while X11 asks for it right away.
Fixes#78
To check if a subsurface is effectively synchronized, we walk the
subsurface hierarchy to look for a non-subsurface parent or a subsurface
being synchronized.
However, when client is closing, the parent surface might already be
gone, in which case we end up with a surface being NULL which causes a
NULL pointer dereference and a crash.
Check if the parent surface is NULL to avoid the crash, and consider
it's already synchronized if it is NULL to avoid further updates.

Before we just set it to "none", but this was not enough since various

(cherry picked from commit ae26cd0774)
When deriving the global scale directly from the current hardware state
(as done when using the X11 backend) we are inspecting the logical
state they had prior to the most recent hot plug. That means that a
primary monitor might have been disabled, and a new primary monitor may
not have been assigned yet.
Stop assuming a primary monitor has an active mode before having
reconstructed the logical state by finding some active monitor if the
old primary monitor was disabled. This avoids a crash when trying to
derive the global scale from a disabled monitor.

These paths implicitly relied on the forwarded IM key events having
a source_device backed by a real HW device. This assumption is no
longer held true since commit b5328c977.
Explicitly check the INPUT_METHOD flag so they are handled as they
should despite not being "real HW" events.
As a follow up to the patch from a95cbd0a, we need to make sure
that the pointer is out of the way as well when monitors changed,
since that's the event that will prevail in some cases. Besides,
this is also consistent with what the code before a95cbd0a was,
which initialized the pointer position in the same way both in
this case and in the real_post_init() function.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/157
Centering the pointer at startup causes undesired behaviour if
it ends up hovering over reactive elements, that might react
to that positioning, causing confusion. This is the case of
the login dialog when a list of different users is shown, as
centering the pointer at startup in that case will get the
user in the center of the screen pre-selected, which is not
the expected behaviour (i.e. pre-selecting the first one).
Fix this by simply moving the pointer out of the way, close
to the bottom-right corner, during initialization.

Right now if Xwayland crashes, we crash, too.
On some level that makes sense, since we're supposed to control the
lifecycle of Xwayland, and by it crashing we've lost that control.
But practically speaking, the knock-on crash adds noise to the logs,
bug trackers, and retrace servers that only makes debugging harder.
And the crash isn't something mutter can "fix", since it's
ultimately from a bug in Xwayland anyway.
This commit makes mutter exit instead of crash if Xwayland goes away
unexpectedly.

In the synchronized subsurface case, the destination list may
contain other elements from previous wl_surface.commit calls.
Resetting the list will leave those dangling frame callbacks
that will lead to invalid writes when those get to be destroyed
(eg. on client shutdown).
The fix is twofold. On one hand, it makes sense not to relate IM (nor
any other) generated events to a HW device. On the other hand, if we
are unfortunate that an IM event is in flight when we are switching
to another TTY, it may arrive at a time when the source device is no
longer existent.
The ResetIdletime API can be used instead of an "XTest" binary to
programmatically reset the idle time, as if the user pressed a button on
a keyboard.
This is necessary since we stopped using the XSync extension to monitor
idletimes, as it didn't consider inhibitors as busy, and mutter's
clutter code ignores "Core Events" as generated by XTest.
This patch will require minimal changes to gnome-settings-daemon's power
test suite so that "key press" idletime resets are triggered through
this D-Bus interface rather than through XTest and a roundtrip through
the X server.

Take idle inhibitions into account for when to fire idle watches as
requested by OS components.
This should stop gnome-session and gnome-settings-daemon considering

computer suspending after watching a film.

Now that we've removed the X11 specific backend of the idle monitor,
add back a cut-down version of it for the explicit purpose of being
told about idle time resets when XTest events are used.
XTest events are usually used by test suites and remote display software
to inject events into an X11 session. We should consider somebody moving
the mouse remotely to be just as "active" as somebody moving it locally.

When moving the pending state of an effectively synchronized subsurface
so it is applied together with the parent, perform a merge of the source
MetaWaylandPendingState into the destination one, instead of simply
overwriting the struct.
The other approach had 2 kind of leaks, one that would happen everytime
a wl_surface.commit happens on a sync subsurface (both surface/buffer
damage regions are leaked). The other more unlikely one would apply on
the rest of pending state data, happening whenever the compositor gets
>1 wl_surface.commit calls on the subsurface before the parent surface
gets its own.
The function has also been renamed to use the more descriptive "merge"
term.
