QSize::isEmpty() will return true if either dimension is 0. On the other
hand, given the current language in the spec, it seems like the client
is allowed to set size constraints per dimension.

Output frames can outlive the output they were created for, so the render loop
might also be deleted by the time the output frame is destroyed or presented
BUG: 487701
It caused bugs and doesn't seem to work anymore, with no complaints about it
not working or an obvious reason for it to exist, so it almost certainly
isn't needed at all.
When the slow update timer fires, it's going to pass m_next.first as the
current time in order to calculate the next transition timings. After
the timings have been calculated, the slow update timer will be started
with an interval of "todayNow.msecsTo(m_next.first)". Since todayNow
is a reference to m_next.first, the time diff will be 0, which will
throw off the night light manager. To fix that, make a copy of m_next.first
and then pass the copy as the current date time to resetSlowUpdateTimers().

Instead, move the outline below the window, so that the visual order of things stays the
same. This also fixes a visual glitch, where the outline is visible for a moment after
maximization, and is above the no-longer-elevated window

While in theory it could be useful with both, I'm not sure that it makes sense
in practice, and the current triple buffering logic doesn't support it.

My recent testing has shown that screen freezes when moving the cursor
cannot be observed anymore. Maybe the issue has been fixed upstream by
some unrelated change. Either way, let's re-enable the hardware cursor
to gather some feedback.
Otherwise, the pipeline state from an earlier hotplug scenario can leave
the pipeline disabled and without a CRTC, which means leasing the output
will fail

If the mode the user has previously set through KScreen isn't available, this falls
back to a different mode without overwriting the user preference. If on the next
hotplug, the desired mode is available again, it then gets chosen instead of the
fallback
BUG: 484037
As per the docs:
Note: This function does not need to be, and must not be, called when
using the software adaptation of Qt Quick.
This sets up RHI on the render control, which in turn sets RHI on the
window, which shouldn't exist when using software rendering.

BUG: 486078
A layer shell window can request a screen edge without having a chance
to map the surface. In that case, no Workspace::windowRemoved() signal
is not going to be emitted because no surface has been mapped. Perhaps
it needs some re-wiring, but on the other hand, it is also more reasonable
to monitor Window::closed() signal.
With this change, the ScreenEdges manager will reject any request to
reserve a screen edge for a closed window. And in addition to that,
the ScreenEdges will unreserve screen edges when the window is closed
rather than when the window is unmapped.

Whilst the XWayland input filter only runs whilst XWayland is running
there is hypothetical window between the wayland connection to xwayland
being disconnected and handleXwaylandFinished, the process exiting. This
should be guarded correctly.
BUG: 480925
If a new drag and drop session is started while there is already one
existing, it's possible to end up in a situation where the
SeatInterface::dragEnded signal is emitted the second time when one of
the data sources is destroyed.
CCBUG: 460374
HiddenPreviews was a hack to not inform X11 that windows were minimised,
so that their previews kept working.
On wayland the user facing setting is not visible but the value is
loaded which is a bad combination.

Write something into the logs when a call goes awry, it can save some
time to the next person porting kwin to a dysfunctional driver.

05a3e2bad9 added `geteuid` use but didn't
add the needed headers. This works by chance on libstdc++ systems via
transitive includes, but it doesn't work on libc++ systems, as reported
downstream in Gentoo at https://bugs.gentoo.org/933120.
The Qt pipeline cache causes a disk sync on every load and save of a
QQuickWindow. This causes a stutter under high disk usage.
The gains from this cache are minimal on our simple scenes on PC
hardware. Especially given mesa has it's own cache, profiling on my
personal laptop showed the pipeline as being 0ms.
There is an upstream patch at
https://codereview.qt-project.org/c/qt/qtdeclarative/+/564411 .
QSaveFile still has a sync, but that should only be hit for the first
non-cached run. I'm also adding a flag to QSaveFile to fix the QML cache
and first run case.
Tested via running kwin with `strace -e
inject=fdatasync:delay_enter=10000000` to simulate a slow flush.
