Do not include it at header side as it is not part of the installed headers.
Only keep it in cogl-gl-headers.h as it is a private header.
Add it to all the source files that depend on it.

This change adds modifier-aware screencasting support to Mutter.
Implicit modifier support is kept for backward compatibility and the
code fallbacks to implicit modifiers in case any new functionality added
for explicit modifier support fails.
The advertised modifiers are retrieved by a call to
eglQueryDmaBufModifiersEXT() function. The "external only" modifiers are
excluded as Mutter uses the buffers created with the explicit modifiers
as renderbuffers. Support for implicit modifiers is checked with a test
allocation since there are drivers that do not support them.
This change also removes various implicit modifier support checks that
disable DMA-BUF screen casting support globally as they are no longer
needed. DMA-BUF support for screencasting is determined by the available
formats and modifiers case-by-case now.
It also effectively enables DMA-BUF screencasting on NVIDIA hardware as
well since GBM buffer objects with linear modifiers are no longer used
by default to create a renderbuffer object for screencasting.

meta_render_device_gbm_allocate_dma_buf() function is updated to take a
list of modifiers. If no modifiers are specified, the modifier is
selected by the allocator, and implicit modifiers are used to import the
created DMA-BUF.

Currently, we blindly apply the transformation matrices of all parent
actors when calculating the absolute coordinates. This means if this
function is called while the window actor containing the surface is in
the middle of a transition (e.g. window open animation), it may return
incorrect values. As this function is used for calculating pointer
confinement bounds for a specific surface, this will result in incorrect
bounds value being used if pointer constraints are applied by the
application at the same time the window is created and the mouse is
inside the surface's bounds when it's created.
Fix this by only applying transformation matrices up to the window actor
of the surface and then calculating the absolute coordinates by adding
the position of the window actor.

They are float in libdisplay-info and our own EDID parsing also returns
a float but when then converted both to an integer. Especially the min
luminance can be <1.
We also don't need a variable for indicating presence of a CTA Static
Metadata block. The values are all zero if it is absent.

Some features depend on libdisplay-info, and making it a feature
option should increase its visibility and adoption.
This makes it required when building with "-Dauto_features=enabled",
unless explicitly disabled with "-Dlibdisplay_info=disabled".
If "-Dauto_features=enabled" is not set, everything remains the
same.
In the future, the libdisplay_info option can be made "enabled" by
default so that it would always be required unless explicitly
disabled.

The function was used only once so just move it content where it is
called. It allows us to drop more cairo paths from the API surface even
if it is not part of a public api

If we don't have a monitor for a surface - e.g. because the surface is
not mapped yet - return the highest scale of all outputs. This makes us
send a preferred scale before a client draws its first frame. The highest
scale is always correct in single monitor cases and arguably a good
option otherwise as scaling down usually looks better than scaling up.
Note that this is currently only used by the fractional scale protocol,
but will also be used for the core `send_preferred_scale()` once we
implement it.

With all early "goto out" paths bypassing wayland, we can pretty
much avoid the goto and use early returns in this function. This
will hopefully improve readability.

We've so far returned FALSE (i.e. PROPAGATE) here, somehow
oblivious of the fact that the core event handler would stop
all non-gesture events directed to windows.
Incorporate this knowledge there, in order to be able to
streamline this piece of event handling in core/ code.

This is Wayland specific code, handle it directly in MetaWaylandPointer.
This also fixes issues with the crossing event itself managing to reach
the window occluded by modals.

With Wayland popups and drag-and-drop using grabs, we
should let window cursors prevail when there is one
in effect.
Also, resort always to the actor as known by the
stage. This fixes the cursor lookup right after crossing
events induced by grabs, e.g. right clicking on the
gtk4-demo textview without motion would keep the I-beam
cursor, now results on the right actor/cursor for the
menu being picked.

Enable grabbing input for popups, and drag-and-drop. Since the very
switch to using ClutterGrab underneath Wayland grabs will challenge
assumptions in existing code, these had to change in one go. A notable
one is that meta_display_windows_are_interactable() is not 100% true
anymore for xdg_popups, at least not the same.
Another change happening in lockstep is MetaDnD no longer having
to funnel events to Wayland, since the grab triggered by Wayland DnD
is now a cause of "compositor grabs", and will naturally receive events
as long as it hold. while "modal".
A number of ad-hoc checks for grabbing state has also been dropped
from src/wayland/ internals, since again Wayland grabs are a reason
for Clutter grabs, plus the mechanism itself will already take care
of focus loss and restoration.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3420>
Add the mechanism to integrate MetaWaylandEventInterface with grabs,
callers may now specify whether a grab is required, in which case
one is created, shared by all the event interface stack.
ClutterStage grab state is also tracked, so the MetaWaylandEventInterface
in charge will focus or unfocus depending on whether input should be
handled (if ungrabbed, or grabbed by the MetaWaylandInput itself), or
not (if grabbed by something else).
At the moment nothing uses this mechanism yet, later commits will add
the first users.

Users of Clutter grabs may listen for notify::revoked changes in
order to know that their grab is no longer in charge of event
propagation, without the use of crossing events.
Since a ClutterGrab may stay in the stack and regain effects,
this notification also happens the other way around.

Now that the backend handles 0-size regions naturally and MetaWaylandPointer
avoids sending wl_pointer.motion on unchanged coordinates, we can use the
default motion handler for the locked pointer constraint.
And since that is the only difference with the pointer constraint event
interface, we can unify them both into a single MetaWaylandEventInterface
handling focus for them both.

The small catch is that MtkRegion (and pixman regions) "optimize away"
0-size rectangles, so a 0-sized region will always be seen as having
a 0,0 origin. We don't want that, so transfer the origin separately from
the region.
While at it, make the Wayland pointer lock use one such 0-size region,
to avoid the 1x1px wiggle room that it currently has (accounting for subpixel
motion).

While every kind of input is seen as coming from the Virtual
Core Pointer in the X11 case, we can largely abstract away from
that fact, and lock XDnD pointer input to the most plausible
source (e.g. a device with a pressed button), instead of only
working with pointer input.
