If the extension is missing, the GPU copy path would not work. The code sets
the error, but forgets to return a failure. Fix this.
While adding the necessary return FALSE, also destroy the EGL context we just
created. Code refactoring shares the destroying code.
Found by reading code.

If the GPU copy path would use a software renderer, fall back to the CPU
copy path. The CPU copy path is possibly faster and avoids screen
corruption issues that were observed on an Intel Haswell desktop. The
corruption was likely due to texturing from an unfinished rendering or
memory caching issues.

Print the pixel format chosen for an output on a secondary GPU for
debugging. Knowing the format can aid in debugging e.g. red/blue channel
swaps and CPU copy performance issues.
This adds a DRM format printing helper in meta-crtc-kms.h. This header
is included in most native backend files making it widely available,
while DRM formats are specific to the native backend. It could be shared
with Wayland bits, DRM format codes are used there too.
The helper makes the pixel format much more readable than a "%x".

When setting up an output on a secondary GPU with the CPU copy mode,
allocate the dumb buffers with a DRM format that is advertised supported
instead of hardcoding a format.
Particularly, DisplayLink devices do not quite yet support the hardcoded
DRM_FORMAT_XBGR8888. The proprietary driver stack actually ignores the
format assuming it is DRM_FORMAT_XRGB8888 which results the display
having red and blue channels swapped. This patch fixes the color swap
right now, while taking advantage if the driver adds support for XBGR
later.
The preferred_formats ordering is somewhat arbitrary. Here it is written
from glReadPixels point of view, based on my benchmarks on Intel Haswell
Desktop machine. This ordering prefers the format that was hardcoded
before.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
These functions allow inspecting which pixel formats a CRTC's primary
plane supports. Future patches will inspect the supported formats and
pick a framebuffer format accordingly instead of hardcoding a format.
The copy list function will be used to initialize a formats list, and
the supports format function will be used to intersect that list against
another CRTC's supported formats.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
This avoids having to hardcode the same fallbacks elsewhere multiple
times when determining what formats might be suitable for a set of
CRTCs. The formats_modifiers hash table is now guaranteed to be
populated with at least something, so future code will not need to
handle it being empty.
The hardcoded fallback formats are a minimal set probably supported by
most hardware. XRGB8888 is the format that, according to ancient lore,
all DRM devices should support, especially if they don't have the
capability to advertise otherwise. Mutter also hardcodes XRGB8888 as the
GBM surface format, so it is already required on primary GPUs.
XBGR8888 matches the most common OpenGL format, sans alpha channel since
scanout hardware has not traditionally supported alpha. XBGR8888 is here
also because Mutter hardcodes that format for secondary GPU outputs when
using the CPU copy path.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
If the IN_FORMATS property is not found, copy the formats from the DRM
plane instead. This is the fallback for getting a list of formats the
primary plane supports when DRM universal planes capability is enabled.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
Rather than picking just one format, parse and store all the formats and
their modifiers.
This gives us a list of supported formats (and modifiers) on a CRTC
primary plane. Later I will be using this list to choose a framebuffer
format instead of hardcoding it.

This is done through gtk-shell ATM. If a window requests focus with
an invalid startup ID, just the demands-attention flag will be set.
The "did user interaction happen in between" checks are left to
meta_window_activate_full/meta_window_focus, by passing the timestamp
of the original launch request.
This version has 2 new requests:
- gtk_shell1.notify_launch notifies the compositor that the requesting
client shall launch another application. The given ID is expected to
be unique.
- gtk_surface1.request_focus notifies the compositor that a surface
requests focus due to it being activated. The given ID is passed to
this process through undetermined means, if it corresponds with a
current startup ID and there was no user interaction in between the
surface will be focused, otherwise it will demand attention.
It scaled the logical monitor rect with scale to get the stream
dimensions, but that is only valid when having
'scale-monitor-framebuffers' enabled. Even when it was, it didn't work
properly, as clutter_stage_capture_into() doesn't work properly with
scaled monitor framebuffers yet.

Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

Shell is using these, which was revealed by
1bbb5c8107 breaking its build when
generating its introspection due to meta_startup_notification_get_type()
not being found.
We keep the class structs private, so in practice MetaStartupSequence
and MetaBackend can't be derived from (the are semi-private).
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.

MonitorManager was inheriting from MetaDBusDisplayConfigSkeleton, this was
causing introspection to see this like a GDBus skeleton object exposing to
clients methods that were not required.
Also, this required us to export meta_dbus_* symbols to the library, while
these should be actually private.
So, make MetaMonitorManager to be just a simple GObject holding a skeleton
instance, and connect to its signals reusing most of the code with just few
minor changes.

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.

Some types were declared in the public headers so that g-ir-scanner
could resolve the types. This caused warnings when using
-Wredundant-decls, so only redeclare them for the gir scanner.
As with the commits earlier, this also adds const qualifiers where
expected. However, the const variables are casted to non-const variants
so they can be passed to glib functions that take non-const variants but
expect const-like input.
Previously, the clipping rectangle passed to
`meta_surface_actor_get_image()` was updated with the actual texture
size, but recent changes in `meta_shaped_texture_get_image()` now keep
the caller's clipping rectangle unchanged.
The implementation of `meta_window_actor_capture_into()` was relying on
the old behavior of updating the passed clipping rectangle, but now that
it's kept unchanged, the actual clipping rectangle used to copy the data
is wrong, which causes either a distorded image or worse, a crash of
mutter.
Use the resulting cairo image size to copy the data instead of the
clipping rectangle to avoid the issue and get the expected size.

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.
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.

The 'cursor-mode', which currently is limited to RecordMonitor(), allows
the user to either do screen casts where the cursor is hidden, embedded
in the framebuffer, or sent as PipeWire stream metadata.
The latter allows the user to get cursor updates sent, including the
cursor sprite, without requiring a stage paint each frame. Currently
this is done by using the cursor sprite texture, and either reading
directly from, or drawing to an offscreen framebuffer which is read from
instead, in case the texture is scaled.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/357
There may be reasons to temporarly inhibit the HW cursor under certain
circumstances. Allow adding such inhibitations by adding API to the
cursor renderer to allow API users to add generic inhibitors with
whatever logic is deemed necessary.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/357
To get a consistent behaviour no matter whether HW cursors are in use or
not, make sure to copy the framebuffer content before the stage overlays
(cursor sprite textures) are painted.

The "current" rect includes the frame, so in order to keep the
titlebar on screen, window movement must be restricted to at
most (height - titlebar_height) past the work area bottom.

Mutter prefers platform devices over anything else as the primary GPU.
This will not work too well, when a platform device does not actually
have a rendering GPU but is a display-only device. An example of this
are DisplayLink devices with the proprietary driver stack, which exposes
a DRM KMS platform device but without any rendering driver.
Mutter cannot rely on EGL init failing on such devices either, because
nowadays Mesa supports software renderers on GBM, so the initialization
may well succeed.
The hardware rendering capability is recognized by matching the GL
renderer string to the known Mesa software renderers. At this time,
there is no better alternative to detecting this.
The secondary GPU data is abused for the GL renderer, as the Cogl
context may not have been created yet. Also, the Cogl context would
only be created on the primary GPU, but at this point the primary GPU
has not been chosen yet. Hence, GPU copy path GL context is used as a
proxy and predictor of what the Cogl context might be if it was created.
Mind, that even the GL flavour are not the same between Cogl and
secondary contexts, so this is stretch but it should be just enough.
The logic to choose the primary GPU is changed to always prefer hardware
rendering devices while also maintaining the old order of preferring
platform over boot_vga devices.

Moves the primary GPU choosing to after all secondary gpu data has been
created.
This makes it possible for a future patch to start looking at secondary
gpu data in choose_primary_gpu () to determine if it is using a hardware
driver or a software renderer.

Initialize the secondary GPU data for all GPUs, even the primary one. By
not looking at the primary_gpu_kms member, a future patch is allowed to
postpone choosing the primary GPU.
A future patch will use the secondary GPU data to decide which GPU will
become the primary GPU.

create_renderer_gpu_data_egl_device () relied on the primary GPU being
already chosen for the "EGLDevice currently only works with single GPU
systems" error message. A future patch will choose the primary GPU after
this, not before, so this check needs to be rewritten before the
initialization order is changed.
The new check is implemented exactly as the error message says: there
must be exactly one GPU, otherwise fail.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/271
Make the choosing and identity of the primary GPU an internal detail to
the native renderer. MonitorManagerKms did not need it for anything.
The primary GPU logic remains unchanged.
This allows follow-up patches to change how the renderer chooses the
primary GPU. It will be easier for the renderer to use private
information for choosing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/271
This is a step towards moving the primary GPU logic into the native
renderer exclusively. In the future the renderer will have one more
criterion on choosing the primary GPU than MetaMonitorManagerKms should
know about: does a GPU offer hardware rendering.
The choosing of primary GPU is separated from the discovery of GPUs.
When GPUs are discovered and added to the list, the MetaGpuKmsFlag is
now populated correctly and used in choosing.
Choosing the primary GPU is done after all GPUs have been found and is
slightly different from before:
- Skipping devices that do not belong to our seat now works instead of
becoming the primary GPU.
- Fall back to any non-platform, non-boot_vga device if neither kind is
found.
The old preference of platform over boot_vga device is kept.
The hotplug path will continue creating a gpu_kms without flags, because
at that point the primary GPU has already been chosen and the flags are
irrelevant.
