As long as the context_priority extension is available request a high
priority context, to help the compositor look fluid despite heavy GPU usage
from other applications at a regular priority.
This becomes sort of pointless if/when unredirection applies, should still
help with overview/workspace switch animations, or if the application is
not fullscreen.
Based on a similar patch by Daniel Stone to Weston.
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.

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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/357
This will be used by the screen casting code to check whether it should
wait for a frame before reading cursor state, or send only the cursor
update, if no redraw is queued.

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.

Add a flags field to MetaGpuKms. In following commits, the flags defined
here will be set and used for choosing the primary GPU.

Keycode lookup can fail for serveral reasons, e.g. if there is no combination of
modifiers and keycodes that can produce the target keysym with the current
keyboard layout.
In case the keycode lookup fails, remap temporarily the keysym to an unused
keycodes.

I saw Meson fade from the sky
On the wind I heard a sigh
As snowflakes cover fallen Makefiles
I will say this last goodbye
Meson is now coming
So ends Autotools days
Future is now coming
And we must away
Over Python and without Bashisms
Through lands where never Meson touched
By silver streams that run down to the Sea
Under parsers, beneath old legacy
Over snow one winter’s morn
I turned at last to paths that lead home
And though where the road then takes me
I cannot tell
We came all this way
But now comes the day
To bid you farewell
Many places I have been
Many sorrows I have seen
But I don’t regret
Nor will I forget
All Makefiles that took that road with me
I bid you all a very fond farewell.
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.
