This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.
This is not quite a X11 clipboard manager, but also works there.

This code takes care of both setting up X11 selection sources whenever
X11 clients claim selection ownership, and claiming selection ownership
on a mutter X11 window whenever other selection sources claim ownership.

This object represents a Wayland selection owner. In order to invert the
FD direction (we hand an output fd, but want an inpu fd), create an
intermediate pipe so we can then create a GInputStream on top of it.

This object represents the selection ownership from an X11 client. The
list of supported targets is queried upfront, so its initialization is
asynchronous. Requests to read contents from the selection will hand
a MetaX11SelectionInputStream.

MetaSelectionSource represents a primary/clipboard/dnd selection owner,
it is an abstract type so wayland/x11/etc implementations can be provided.
These 3 selections are managed by the MetaSelection object, the current
selection owners will be set there, and signals will be emitted so the
previous selection owner can clean itself up.
The actual data transfer is done through the meta_selection_transfer_async()
call, which will take a GOutputStream and create a corresponding
GInputStream from the MetaSelectionSource in order to splice them.

Meson 0.50.0 made passing an absolute path to install_headers()'
subdir keyword a fatal error. This means we have to track both
relative (to includedir) paths for header subdirs and absolute
paths for generated headers now :-(

This adds the required bits to wayland surfaces and ties them up
to the compositor parts.
It is based on and very similar in nature to buffer transforms.
From the specification:
> The global interface exposing surface cropping and scaling
> capabilities is used to instantiate an interface extension for a
> wl_surface object. This extended interface will then allow cropping
> and scaling the surface contents, effectively disconnecting the
> direct relationship between the buffer and the surface size.

Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

pkg-config files for mutter are generated using *_pkg_deps as requires, but
programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.
So list packages needed only by mutter itself inside *_pkg_private_deps and
don't expose such packages to pkg-config, but only use them at build time.

Soname of the libraries should be the major version number, while the version
triplet is currently used:
objdump -p libmutter-4.so.0.0.0 | grep SONAME
SONAME libmutter-4.so.0.0.0
While is expected to be only libmutter-4.so.0
Fix all shared libraries by setting valid version and soversion.

This is a GAppLaunchContext subclass meant to replace usage of
GdkAppLaunchContext in gnome-shell.
Launch contexts get created from the MetaStartupNotification as
they are closely related. The messaging underneath depends on
the availability of a X11 display, if there is one we go through
it (and libsn). If there is none, we still create startup sequences
manually for wayland clients.
If a library is provided in the positional arguments, then meson
defaults to installing the .pc file in a 'pkgconfig' subdirectory
in the library's install location. We want the files in the regular
$libdir/pkgconfig rather than $libdir/mutter-$api/pkgconfig, so
specify the location explicitly in the parameters.

This is a simple libcanberra abstraction object, so we are able
to play file/theme sounds without poking into GTK+/X11. Play
requests are delegated to a separate thread, so we don't block
UI on cards that are slow to wake up from power saving.
Dependencies are added automatically, and we no longer get warnings
like:
clutter/clutter/meson.build:628: DEPRECATION: Library mutter-clutter-4
was passed to the "libraries" keyword argument of a previous call to
generate() method instead of first positional argument. Adding
mutter-clutter-4 to "Requires" field, but this is a deprecated behaviour
that will change in a future version of Meson. Please report the issue
if this warning cannot be avoided in your case.
Those are stub specialized classes for MetaWindowActor. This will
help ensuring that we do not execute X11-specific code paths on
pure Wayland clients.
The relationship between the window actor and the surface is the
following:
* Wayland: MetaWindowActorWayland + MetaSurfaceActorWayland
* X11: MetaWindowActorX11 + MetaSurfaceActorX11
* Xwayland: MetaWindowActorX11 + MetaSurfaceActorWayland
It is not possible to have MetaWindowActorWayland backed by a
MetaSurfaceActorX11 surface.

This makes the build less verbose, as all .gir generation except for
clutters didn't pass --quiet to g-ir-scanner, making it output long
linking commands. Do this by adding a common introspection_args
variable.
While at it, put -U_GNU_SOURCE in there too, as it was always passed
everywhere as without it the scanner would log warnings.
Typically, to stream the content of a window, we need a way to copy the
content of its window-actor into a buffer, transform relative input
coordinates to relative position within the window-actor and a mean to
get the window bounds within the buffer.
For this purpose, add a new GType interface `MetaScreenCastWindow` with
the methods needed for screen-cast window mode:
* meta_screen_cast_window_get_buffer_bounds()
* meta_screen_cast_window_get_frame_bounds()
* meta_screen_cast_window_transform_relative_position()
* meta_screen_cast_window_capture_into()
This interface is meant to be implemented by `MetaWindowActor` which has
access to all the necessary bits to implement them.

This object takes care of mapping absolute devices to monitors,
to do so it uses 3 heuristics, in this order of preference:
- If a device is known to be builtin, it's assigned to the
builtin monitor.
- If input device and monitor match sizes (with an error margin
of 5%)
- If input device name and monitor vendor/product in EDID match
somehow (from "full", through "partial", to just "vendor")
The most favorable outputs are then assigned to each device, making
sure not to assign two devices of the same kind to the same output.
This object replaces (and is mostly 1:1 with) GsdDeviceMapper in
g-s-d. That object would perform these same heuristics, and let
mutter indirectly know through settings changes. This object allows
doing the same in-process.
If meson tries to get ahead and generate object files for tests
at the same time than building libmutter, those may randomly fail
if meson did not create the libmutter generated headers yet.
Add those to the declared dependency, so the files are ensured to
be created before anything gets to use it.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/404
Add support for getting hardware presentation times from KMS (Wayland
sessions). Also implement cogl_get_clock_time which is required to compare
and judge the age of presentation timestamps.
For single monitor systems this is straightforward. For multi-monitor
systems though we have to choose a display to sync to. The compositor
already partially solves this for us in the case of only one display
updating because it will only use the subset of monitors that are
changing. In the case of multiple monitors consuming the same frame
concurrently however, we choose the fastest one (in use at the time).
Note however that we also need !73 to land in order to fully realize
multiple monitors running at full speed.
Meson uses the 'dependencies' field to determine and
parallelize build steps, but that isn't entirely true
with 'link_with'; this might cause a race condition
when generating header files while trying to build
them.
Fix that by only using 'dependencies' instead of 'link_with'.
This commit adds meson build support to mutter. It takes a step away
from the three separate code bases with three different autotools setups
into a single meson build system. There are still places that can be
unified better, for example by removing various "config.h" style files
from cogl and clutter, centralizing debug C flags and other configurable
macros, and similar artifacts that are there only because they were once
separate code bases.
There are some differences between the autotools setup and the new
meson. Here are a few:
The meson setup doesn't generate wrapper scripts for various cogl and
clutter test cases. What these tests did was more or less generate a
tiny script that called an executable with a test name as the argument.
To run particular tests, just run the test executable with the name of
the test as the argument.
The meson setup doesn't install test files anymore. The autotools test
suite was designed towards working with installed tests, but it didn't
really still, and now with meson, it doesn't install anything at all,
but instead makes sure that everything runs with the uninstalled input
files, binaries and libraries when running the test suite. Installable
tests may come later.
Tests from cogl, clutter and mutter are run on 'meson test'. In
autotools, only cogl and clutter tests were run on 'make check'.
