This reverts commit b31baaf0cd.
It's still a good idea to show the task switcher even if there's only
one window in order to provide the user feedback about their action.
Since the task switcher is not shown when there's only one window, it
can be confusing and lead to thinking that the task switcher is broken.
It also fixes a regression which prevents alt-tabbing to the only
remaining minimized window.

While this should really never happen in the first place, if the kernel still accepts
atomic commits, this is better than the screen(s) freezing and never recovering.

Instead of calling glFinish, which blocks until it's done and has high CPU
usage on NVidia, use EGL_ANDROID_native_fence_fd to get an explicit sync
fd, which the commit thread automatically waits on before committing the
buffer to KMS.

In the late Plasma 5 times we agreed that it would be better to drop
"active mouse screen" option and stick with last interacted screen
approach instead. However, it was forgotten and nobody has pursued this
goal, so let's hide the option in the system settings ui at least.
The option is not completely removed because some parts of kwin would
need adjustments.
The new scale value is written but it's not flushed to the disk so
when kcm_fonts_init and kcm_style_init run, they use the old scale
value.

It can be used to simplify state tracking in some effects. The
restriction exists because there used to be separation between normal
and closed windows (Toplevel and Deleted), and one could reference
only Deleted windows. So it was easier just to forbid referencing still
alive windows.
Imagine the following case:
- the window is hidden, slideOut() is called but no deleted reference is
created because the window is not deleted
- the window is closed, slideOut() won't be called because the window is
hidden and SlidingPopupsEffect::slotWindowClosed() ignores closed windows
that are already hidden
- the window is deleted in meanwhile
- the sliding popups effects attempt to delete m_animations[w] entry,
but since "w" is a dangling pointer at this point, visibleRef is going
to access released memory
To fix that, make slideOut() always ref the window.
When a QPromise reports results, it's not necessary that the
QFutureWatcher is going to report it immediately. That can happen at
some point in the future, which is okay according to the QFuture api
contract.
Due to that, we cannot assume that the stored Output and EffectWindow
objects pointers are valid when the QFutureWatcher::finished is emitted.
kwin_wayland has become unstable. Sometimes it works fine, sometimes it
is randomly killed. Things are quite bad after kwin_wayland --replace.
This reverts commit 71ade59f4b.
It makes code more intuitive, updating X11 specific stuff should not be
needed to update the grid layout. Another advantage that this change
brings is that it should be possible to decouple X11 bits from the
virtual desktop manager completely, might be useful for running multiple
xwayland instances.
The documentation of NETRootInfo::activate() says that it should be
called after creating the NETRootInfo object to read properties.
However, it's called in two places: VirtualDesktopManager::setRows()
and Workspace::initializeX11(). At quick glance, there's no justifying
reason to call activate() in setRows(), it doesn't fit the purpose
of setRows().
This change re-arranges NETRootInfo initialization code so it makes
more sense.
Allows to notify systemd whether kwin is still running and possibly
restart the service if it stops responding.
Use Type=notify-reload to watch the kwin service. This will make it so
we receive SIGHUP rather than SIGTERM on the wrapper which we can handle
gracefully and stop the kwin process and restart as expected.

The current implementation of the `<N>` suffix is still buggy and its
benefits are doubtful. One could argue that visual aids such as window
thumbnails or highlighting the windows are better. On its own, these
numbers don't have strong connections to the windows and can change on
a whim.
This way no extra buffer space is going to be wasted for a decoration
that isn't there, and it might be nicer for fractional scaling as kwin
won't need to deal with border size voodoo cases.
This is because the Overview will activate itself at the end of a 1:1 gesture,
and a toggle action might actually deactivate it rather than activate it.
With how Xwayland scaling works, KWin assumes the window already uses the
new coordinate system - but that doesn't happen until Xwayland and the client
know about the new size as well.

The failure might be from the commit reordering going wrong in some way.
The total accumulated state might still work even if an individual commit
does not though, so before considering the whole frame lost, merge all the
commits and try again
This was just done because of the wrong assumption that displays needed that
to show the full native gamut. That turned out to be an amdgpu bug though; with
that fixed, most of the 0-100% range is wildly oversaturated.
To make the slider more intuitive, this changes the sdr gamut wideness to instead
interpolate to the native display primaries as indicated by the EDID.
