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

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.

This check was originally added because `window` was actually used.
While technically correct, there's no reason to keep it around.
Fixes: 4736f873f2 ("compositor/native: Add support for direct scanout per view")
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177>
Until now we only supported direct scanout to the primary plane if the
buffer size perfectly matched the display size.
Since display controllers usually support scaling and cropping buffers
highly efficiently, try to let them do the job. This is usually helpful
if wp_viewporter is used by the client or Mutter uses fractional
scaling.
This has several advantages:
- Games (e.g. SDL2 based ones) can almost always hit direct scanout
paths in fullscreen mode. Notably when fractional scaling is used or
the game renders in a non-native resolution (or both).
- Video players using YUV buffer formats and wp_viewporter can easily
hit direct scanout paths, making displaying video very power
efficient as the 3D engine is not used at all.
Note that this still only uses the primary plane, no overlay or underlay
planes, making this change comparatively low risk.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177>
In a following commit we will start supporting scaled and croped
surfaces, thus, in preparation, update the logic to three common cases:
1. only one surface, fullscreen (most apps)
2. a content surface and a black background surface which the client
does not want to unmap, fullscreen
3. top-level subsurface covers the whole window and is opaque (Firefox)
The remaining currently supported cases should be fairly uncommen and
and harder to compute.
Note that we already check that the window cover the stage view in
MetaCompositorView.

This allows GNOME Shell to communicate the user desired XKB model
to the compositor instead of sticking with the pc105 default.
Particularly useful for those with a custom keyboard layout/irregular
keyboards.

The texture coordinates of all planes should be the same in theory so
using the coordinates of the first plane works.
The reason for this change is that Cogl somehow doesn't manage to get us
the correct coordinates for the 3rd plane in some circumstances. This is
really a workaround but not wrong in any way.

Calculating the mipmap width as half of the texture width leads to a
mipmap width of zero for textures with width of 1 which leads to an
early exit instead of a mipmap texture.

We currently offer the mechanism for GNOME Shell to implement, and
while this is not exercised often (our entries are typically surrounded
by a ClutterGrab ensuring key events, so this is reserved to grab-less
entries, probably there are some in extensions), this is arguably
something Mutter should cover by itself without GNOME Shell guidance.
This is only necessary on the X11 backend, although it is conceptually
more tied to the MetaX11Display connection, so perform the focus
tracking there only if not running as a Wayland compositor (i.e. --x11).
This avoids the only case where the low-level
meta_x11_display_set_input_focus_xwindow() function is used, or rather
makes it completely a MetaX11Display implementation detail, leaving
only the MetaDisplay API as the high-level entry points to handle
window key focus.
The public API that allowed GNOME Shell to implement these mechanisms
is also gone in this commit.

Changing the MultiTexture may require a different set of pipelines when
the texture format is different. We keep track of the attached
MultiTextureFormat just like we do for the width and height.
This fixes misrendering when a client attaches buffers with different
MultiTextureFormats to the same surface.

Transfer none was achieved using a stack GArray in the stage which
would get resized to 0 at the end of every frame to "free" it.
In the case of direct scanout however, painting the next frame only
happens after leaving fullscreen again. Until then the array just kept
growing and because GArrays don't reallocate when shrunk, this memory
remained allocated even after leaving fullscreen.
There is no cache benefit from storing paint volumes this way, because
nothing accesses them after their immediate use in the calling code.
Also the reduced overhead from avoiding malloc calls seems negligible as
according to heaptrack this only makes up about 2-3% of the temporary
allocations.
Changing this to transfer full and removing the stack array simplifies
the code and fixes the "leak".

The current usage of MetaWindow::unmanaging may result in confused
focus window lookups while undoing the MetaWindowDrag grab (i.e.
still pointing to the window that is now being unmanaged).
The meta_window_unmanage() function itself takes care of changing
focus outside of the window being unmanaged, so postpone the
MetaWindowDrag undoing to a point after that is done.

Split the struct into mutable and immutable parts. Access the mutable
parts via getters and the immutable parts via a single struct. This
avoids copying around the immutable parts.
