The config may have HDR or WCG enabled, and the driver or display settings changed
since then to make it impossible to actually enable either.
The config values stay unchanged when this happens, so reconnecting the display with
HDR support will automatically turn it on again.

the behavior of converting negative floating-point numbers to unsigned
integers is undefined. It is necessary to keep the conversion behavior
consistent between ARM and x86 platforms.
through the above conversions, all become the two's complement of
negative numbers.

wl_surface size is not used when re-arranging surfaces. It also results in
excessive configure events.
Note that it can be useful for updating strut rects, but we could use the
next geometry, which is even preferrable over the frame geometry as the
Workspace would use proper struts earlier.
Otherwise, Qt thinks the old context is still current and will do things like
destroying VAOs with KWin's context, which ends up destroying the VAO of the
context and breaks rendering.

While the primary plane delivers a high enough refresh rate for the cursor to be
at least usable, delay cursor updates to be in sync with the primary plane. This
avoids stutter of the content being shown on the primary plane.
Because amdgpu doesn't handle this correctly at the moment, this feature is guarded
behind the KWIN_DRM_DELAY_VRR_CURSOR_UPDATES environment variable.
See https://gitlab.freedesktop.org/drm/amd/-/issues/2186 for more details on that.
In almost all cases it's duplicated in the name, and if the user manually
changes the name, the custom name should be shown without additional numbers

The user may have no usecase for the grid view mode, i.e. they may want
to activate overview, do their thing, and then return back to normal
desktop. However, with the current behavior, there's one extra step
(switch to grid mode) in order to go back to desktop.
In hindsight, we should have added different screen edge actions for
overview and grid modes. This can be done in 6.1.
BUG: 481335
The overview and the zoom effect repaint the whole screen every frame.
But the problem is that there are cases when there's nothing to repaint.
I'm not quite sure why it happens. Maybe overview and other effects
should honor the repaint region, but on the other hand, they don't need
to because of the fullscreen effect api promises.
This change forces overview and zoom effect to use "generic paint" code
path in the workspace scene to force infiniteRegion() repaint regions.
BUG: 481523
Zoom push tracking now considers the layout of the user's monitors, accounting for situations where the monitor layout doesn't form a perfect rectangle. These changes help prevent the zoom area from being unable to reach certain areas of the workspace depending on which edge of which screen the user pushes against.
One known issue is that, if the mouse moves too quickly, the zoom area can sometimes imperfectly track the movement. It will look the same as the original bug (areas of the screen will appear to be cut off/unreachable), but moving the mouse in the opposite direction a tiny bit snaps the zoom area back to where it should be.

@teams/qa Heads-up that I'm very blind, and this is the first time I've ever contributed to a KDE project. I've tested the changes on my system and they fix the bug, but I want to make sure I didn't break anything in the process.
DrmOutput::setDrmDpmsMode() already takes care of reverting any
pending output pipeline changes, but the aboutToTurnOff signal from
setDpmsMode() needs an explicit wakeUp signal to cancel it out.

NETWM forces a weird X11 dependency on KWin that doesn't necessarily
match what we want to do. Instead we decouple such a central class in
KWin like it's Window from KWindowSystem X11 support.

Geometry restores were only saved when maximize or fullscreen changed, which is
not the only time the geometry restores change. This adds a signal to Window for
that, which fixes a few bugs with windows being moved between screens while
maximized or fullscreened
kwin does not support true multiscreen drag and drops. Events are sent
to an offscreen location of the screen initiating the drag. Therefore it
is important that off-screen items do not process drop events
BUG: 481331
This check is old and I'm not sure why it even exists. It should not be
needed in general.
The problem with this check is that when interactive move/resize
operation finishes, the seat input transformation is not synchronized.
Replace old "closest" and "natural" layout algorithms with new layout
algorithm. The new layout algorithm tries to
- use screen space efficiently, given diverse geometries of windows
- be aesthetically pleasing
- and minimize movement of windows from initial positions.
More concretely, find a layered layout, where each layer, or strip, is a
row or column. Ensure that different strips have similar widths, and use
binary search to find a packing with similar aspect ratio to the layout
area. Within each strip, minimize horizontal movement (for rows) or
vertical movement (for columns) of windows.
Run time is O(n) (up to log factors), where n is the number of windows.

i915 doesn't implement the Colorspace property correctly, so exposing this
feature makes it look like our HDR implementation is broken. This hides the
HDR checkbox in system settings until Intel fixes their driver
For testing purposes, users can still opt into this with the environment
variable KWIN_DRM_ALLOW_INTEL_COLORSPACE.
Overview and Grid modes have shortcuts assigned to them. While they
provide a way to toggle the overview effect between on and off state, in
other words overview <-> off or grid <-> off, it's not possible to move
between the modes by pressing those shortcuts, e.g. off -> overview ->
grid -> overview -> grid -> ... -> off.
The culprit seems to be that EffectTogglableState has two "inactive"
states - Inactive and Stopped. It's counter-intuitive and needs a further
cleanup.
To make switching between overview modes work, this change makes
EffectTogglableState::toggle() toggle the state based on the Active state.
There's only one active state.

The section header being now a QQC2.ItemDelegate needs to explicitly
set the width to be visible.
The ContextualHelpButton size was getting constrained by the parent
layout's being adjusted to just the label height.
OutputTransform::Normal is handled by doGrabTexture().
If the texture transform is neither normal nor flip-y, the GPU is going
to be used to transform the texture, however since it doesn't flip the y
axis, doGrabTexture() will flip the y axis on the cpu side. To fix that,
make the contents of backingTexture mirrored vertically.
