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.
Opaque is a QRegion in logical pixels, using .toRect will round to the
nearest integer in either direction. This can mean an area is considered
opaque outside the rendered area, leading to glitchy contents on
shadows.
This is most noticable on on X11 windows when fractional scaling is
used.
Long term I hope to move Item::opaque to QList<QRectF> and
WindowPrePaintData::opaque to device pixels.
QWindowSystemInterface goes via QGuiApplication which updates some
internal properties. Most notably QGuiApplication::lastCursorPosition
which is used by advanced menu closing behaviour.

otherScreenThumbnail is used to fake a window thumbnail being dragged
half in the old screen, half in the "new" one (or even more than two)
right now the condition to use it is purely the "real" thumbnail x
or y change, but sometimes especially when the item has just been created
and is being laid out it might trigger an itemDraggedOutOfScreen
when no-one was dragging.
We should never make otherScreenThumbnail visible when we aren't dragging
a thumbnail, so check for Drag being active in the source item.
the item will be kept visible even if drag becomes inactive as before,
as it still needs to be visible for the reset animation

By default the translation domain of KQuickManagedConfigModule is the
unique identifier within the namespace of the plugin, but those i18n
strings belong to kwin.po.
Though there are 3 common CVD types, each individual can have different
color perception level, and the default intensity might not be suitable
for everyone, so add an intensity slider to select how much the filter
affects the display.
Modifiers for global shortcuts are handled differently from normal shortcuts,
because they need to consider modifiers that are consumed by xkb for keyboard
layout transitions and similar. This restriction is not relevant for custom
tiling.

SeatInterface currently has a separation of kwin's focus scope to
pointer input with early return guards in notifyPointerEnter and
notifyPointerLeave where clients don't get pointer events.
However we don't update the initial state when a drag is started, this
patch notifies sends a pointer leave to the new drag target before the
data_device enter so things are consistent.
This also brings it in line with Weston and Mutter.
notifyPointerLeave has it's early return removed as for wayland windows
as we know nothing will have pointer focus.
Instantiators create objects when they're added to a model, and
deference when when they're removed from the model.
When we explicitly set a parent in onObjectAdded we're creating a second
reference. This does get cleaned up later, but not in the same frame.
This brings us in line to what QQmlRepeater (which works with items)
does internally for items being added and removed.
BUG: 478777
Reducing approachGeometry is not needed.
During edge creation, createHorizontalEdge and createVerticalEdge
already substract the needed cornerOffset, and edges reserved by client
windows shouldn't be reduced in geometry.
In addition, during display, ScreenEdgeEffect confines the painted area
to approachGeometry. So approachGeometry shouldn't be reduced in
advance.

The original assumption was that once PointerInputRedirection starts
pushing cursor sources to cursors, they cannot be null. In many cases,
it is true, but the tests are a bit special as many of them lack
wl_pointer.set_cursor requests, so it's possible to set a null source.
As an example, when the pointer moves from the decoration to the
surface. On the other hand, it also does make sense to allow having
no source connected.
While tabbox switching is usually a keyboard operation, we offer also
a mouse-friendly way to launch it via screen edges, and should allow
to switch directly on mouse click.

The blur geometry is scaled in the global coordinate space, while it
works fine with integer scale factors, it's not okay with fractional
scale factors as it doesn't match how the ItemRenderer snaps quads to
the pixel grid.
Note that blur behind apps can be still off by one pixel, but it
should be harder to notice it. In order to fix it, it would be great
to apply effects behind Items, which is on my todo list.
Window::layoutDecorationRects() uses KDecoration2::Decoration::rect() to
get the bounding decoration rect.
While Decoration::rect() should normally match Window::rect(), they can
diverge for a brief moment during async geometry updates. The worst
possible case is that the cached item quads may not be invalidated when
the geometry updates saddle.
To fix that, make DecorationItem monitor decorated client size changes
instead of window frame geometry changes. The reason for that is that
Decoration::size() is effectively decorated client size with added border
margins.
