DRM_EVENT_CONTEXT_VERSION is the latest context version supported by
whatever version of libdrm is present. Mutter was blindly asserting it
supported whatever version that may be, even if it actually didn't.
With libdrm 2.4.78, setting a higher context version than 2 will attempt
to call the page_flip_handler2 vfunc if it was non-NULL, which being a
random chunk of stack memory, it might well have been.
Set the version as 2, which should be bumped only with the appropriate
version checks.

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.
This is the last remaining feature necessary to achieve
parity with the Autotools build.
A few changes were made to the install locations of the
tests, in order to better acomodate them in Meson:
* Tests are now installed under a versioned folder (e.g.
/usr/share/installed-tests/mutter-4)
* The mutter-cogl.test file is now generated from an .in
file, instead of a series of $(echo)s from within Makefile.
Notice that those tests need very controlled environments
to run correctly. Mutter installed tests, for example, will
failed when running under a regular session due to D-Bus
failing to acquire the ScreenCast and/or RemoteScreen names.
The Wacom Xorg driver assigns a serial number of 1 for any pad that doesn't
have a serial. libinput assigns 0. Just treat 1 as 0 here, there are no pens
with a real serial 1 anyway.

Implements the `MetaScreenCastWindow` interface for screen-cast
`RecordWindow` mode.
`meta_window_actor_capture_into()` implementation is still pretty crude
and doesn't take into account subsurfaces and O-R windows so menus,
popups and other tooltips won't show in the capture.
This is left as a future improvement for now.

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.

To be able to cast windows, which by definition can change in size
dynamically, we need a way to specify the video crop meta to adjust to
the window size whenever it changes.
Add VideoCrop support with a new optional hook `get_videocrop()` in the
`ScreenCastStreamSrcClass` which, if defined, can let the child specify
a rectangle for the video cropping area.

Switch-configs are only to be used in certain circumstances (see
meta_monitor_manager_can_switch_config()) so when ensuring
configuration and attempting to create a linear configuration, use the
linear configuration constructor function directly without going via the
switch config method, otherwise we might incorrectly fall back to the
fallback configuration (only enable primary monitor).
This is a regression introduced by 6267732bec97773.

Which eliminates the 1px jitter that was visible when dragging windows,
and eliminates the flickering that was visible when pushing the cursor
against the right/bottom edges of the screen.
The shader used for computing a vignette currently has two
problems:
* The math is wrong such that the vignette isn't stretched
across the whole actor and so ends abruptly
* There is noticeable banding in its gradient
This commit corrects both problems by fixing the computing
and introducing noise dithering.
If a display device (touchscreen, tablet with libwacom integration flags)
does not receive a monitor through settings. Delegate on the
MetaInputMapper so it receives a mapping through heuristics.
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.
Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.
In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.
Removing it means less code, less branches when running,
and one less config option to deal with.
This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

Externally setting the sync-to-vblank setting was a feature
added as a workaround to old Intel and ATI graphic cards, and
is not needed anymore. Furthermore, it doesn't make sense to
change it on a compositor whatsoever.
This commit removes all the ways to externally change this
setting, as well as the now unused API.

The nested stage tries to emulate how CRTCs are drawn, but fails to do
this when a stage view is scaled as it didn't adapt the viewport size
according to the stage view scale.

Add MUTTER_DEBUG_DUMMY_MONITORS_SPECS env variable support so that you can define
a ':' separated list of monitor specs in the form of WWWxHHH@RR that will be
available for configuring the nested mutter.
When calculating the logical monitor layout size given a scale, don't
risk precision loss by float to int casting, which could result in a too
small layout.

Placing persistant Wayland popups (e.g. not menus etc) in the o-r layer
breaks stacking order with other window trees (e.g. other client
windows), as the menu would get stuck in the o-r layer, i.e. on top,
even if the parent of the popup got lowered.
Fix this by placing the popups in the normal layer, relying on
transient-ness to keep stacking correct.
When destructing a xdg_toplevel, we'll disassociate the actor from the
MetaWaylandSurface, to allow it to animate out. After having done this,
avoid trying to set it as unreactive when unsetting the window.
This fixes the runtime warning:
clutter_actor_set_reactive: assertion 'CLUTTER_IS_ACTOR (actor)' failed
Before processing the buffer damage region, intersect it with the buffer
rectangle to avoid trying to damage content outside the surface.
This fixes the runtime warning "GL error (1281): Invalid value"
happening when a client posts too large buffer damage larger.
We haven't supported disabling stage views in the native backend since

backends/native: Stop supporting stage views being disabled
There were still some left over checks; lets remove them.

This adds the required bits to wayland surfaces and ties them up
to the compositor parts.
The central part here is to recalculate the surface size accordingly
and to translate surface damage into buffer damage.
The choosen approach additionally lays groundwork for wp_viewporter
support, which is closely related in its nature.
A further explanation of buffer transforms from the specification:
> The purpose of this request is to allow clients to render content
> according to the output transform, thus permitting the compositor
> to use certain optimizations even if the display is rotated.
> Using hardware overlays and scanning out a client buffer for
> fullscreen surfaces are examples of such optimizations.
This adds the necessary bits to support Wayland buffer transforms.
The main part here is to properly setup the Cogl pipeline
and to recalculate the size of the painted area accordingly,
so culling etc. still works.
The choosen approach additionally lays groundwork for Wayland
wp_viewporter support.

Commit 70036429bd4 mixed drag_origin and drag_surface, leading to warnings
and invisible drag icon. Fix this up so we correctly set up the feedback
actor. This will correctly display the DnD icon alongside the pointer.
It is meant to hold surfaces that require a ClutterActor, just like wl/xdg
shell surfaces and subsurfaces. Make it inherit from MetaWaylandActorSurface
so it gets that for free.
The type declaration is also made completely private, in order to avoid
cyclic dependency between meta-wayland-surface.h and
meta-wayland-actor-surface.h. We just require the GType fro assign_role()
anyway.
Modal ungrabs may be followed by other clients trying to grab themselves,
flush the connection so we ensure the right order of events on the Xserver
side.
An example of this is js/ui/modalDialog.js in gnome-shell, as the alt-F2
dialog may launch X11 clients trying to grab themselves, commit a40daa3c22
in gnome-shell handled the case and added a gdk_display_sync() call to
ensure no grab existed at the time of executing.
This commit aims to achieve the same built in MetaBackend. A full sync
seems excessive though, as we just need to make sure the server got the
messages queued before the other side tries to grab, a XFlush seems
sufficient for this.
