Allow users to configure a virtual edge barrier between screens.
The pointer will only cross over to the other screen after the distance
travelled surpasses edgeBarrier.
Reduce the speed during interactive moveresize, at edges that trigger,
and at the corner.
Only supports wayland. Doesn't have X11 support since it is far too
complicated there.

When the output layout changes, the Workspace is going to update the
struts and then go through every window and see whether it should be
moved or resized.
On the other hand, the layer shell windows react to output changes on
a timer. Furthermore, it's not synchronized with the workspace rearranging
the managed windows. It means that when Workspace::desktopResized() runs,
the panel struts can be slightly outdated, i.e.
- An output layout change occurs
- Workspace::desktopResized() is called but the struts can be wrong
- some time later, LayerShellV1Integration::rearrange is called, it
fixes layer shell window geometries and struts
- after the layer shell integration has finished rearranging the
layer shell windows, it calls Workspace::desktopResized(), but the
damage had already been caused
With the proposed change, the Workspace and the LayerShellV1Integration
will rearrange the windows in sync.

Now that we have Wayland around, there's a whole branch of dependencies
that shouldn't be necessary anymore.
This allows to build KWin without all of it, allowing us to have a much
more compact alignment for cases where all the legacy software isn't
necessary anymore.
Bundle KWindowSystem X11-specific headers into it too, since it's part
of the same process.

If the client is slow, kwin can receive _NET_WM_MOVERESIZE requests
after user has released mouse buttons. Ideally, the window manager
should refuse starting an interactive move/resize operation in such a
case so it's still possible to finish moving or resizing the window
by releasing mouse buttons.
Strict geometry disables certain user activites; full screen requests
and only sending configure events at sizes the client claims to support.
This was added as a workaround for xterm in 19 years ago. It's a client
side bug as applications can still choose to ignore the configure event,
so kwin shouldn't have to sanitise them in advance. xterm seems to have
fixed it's bug, and pragmatically we know not all window managers
perform these checks so most clients should not be relying on it.
On Wayland this additional check is proving problematic, the handling of
scaling especially fractional scaling is hitting cases where it's better
to always ask the client to do what kwin wants.
Tests that refer to sizeIncrements are dropped as they are only used in
the strict geometry passes which is being obsoleted. Resizing in general
is still tested.

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.

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.
There is a mix of cursor shape names from the CSS W3C specification and
non-spec ones, which is confusing when deciding what cursor shapes need
aliases in Cursor::cursorAlternativeNames().
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 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.
At the moment, the desktop layout in _NET_DESKTOP_LAYOUT overwrites new
desktop layout with outdated information. This happens because kwin tries
to honor the desktop layout set by the pager. However, kwin itself
already acts as the pager. The pager applet in plasma doesn't attempt to
maintain _NET_DESKTOP_LAYOUT with proper values.
On the other hand, kwin trying to both update and also sync its state to
_NET_DESKTOP_LAYOUT and _NET_DESKTOP_NAMES has created a series of
issues, like lockups or rendering glitches.
Given that the window manager can ignore these properties, and the fact
that kwin already does act like a pager, this patch makes kwin ignore
external updates to _NET_DESKTOP_LAYOUT and _NET_DESKTOP_NAMES.
In order to modify the desktop layout on X11, use the dbus api. On
Wayland, either the dbus api or the virtual desktop wayland protocol.

A window is added to the workspace when it's mapped. It's assumed that
the first Window::windowShown signal indicates that. But it's not
entirely true. For example, if setHidden(false); setHidden(true); are
called in succession, the window will be marked as ready for painting
even though it isn't.
The Window::readyForPaintingChanged() signal fixes that. It's emitted
when the window is actually mapped.
At the moment, if the workspace extends or shrinks by an output, the
hidden panel will be shown. It doesn't make sense in all cases.
Furthermore, no screen edge will be reserved if the layer surface has
some margins.
To address that, allow "floating" panels reserve screen edges and also
make kwin try harder to preserve window edges if the output layout
changes.
CCBUG: 448420
The new window rule allows to overwrite the stack layer. It can be
useful on wayland to force picture-in-picture surfaces (which are
xdg-toplevels at the moment) to be placed above fullscreen windows.
Keep above flag is unsuitable because fullscreen windows are placed
higher "above" windows.
CCBUG: 466016
Currently there is a 150ms delay before screen edge actions and
hotcorners are triggered; the cursor has to spend that much time there
before they'll activate. This is good for preventing accidental
activations, but also prevents and delays deliberate activations, which
are likely to be more annoying for the user.
To alleviate this, the delay is reduced to 75ms, which still prevents
most of the accidental activations in my testing, while making
deliberate activations faster and easier.
If the user wants to move a tiled window but changes their mind and tiles the window back to the previous
position, quickTileGeometryRestore() will return an error value beacause m_electricMaximizing is true and
the m_electricGeometryRestore is the same as the geometry of the window in the last tiled mode.
Now the geometry restore of the tiled window is true when starting interactive move, so we no longer need
to precompute it.
Changes for testQuickTilingPointerMove:
We need to attach a new image after the tiling window, so that updateElectricGeometryRestore can obtain
the same framegeometry as the framegeometry obtained during actual runtime.
Now testQuickTilingPointerMove can detect the error：If the user wants to move a tiled window but changes
their mind and tiles the window back to the previous position, quickTileGeometryRestore() will return an
error value beacause m_electricMaximizing is true and the m_electricGeometryRestore is the same as the
geometry of the window in the last tiled mode.

Currently when input panel is using overlay mode and the cursor rectangle
is below or above the screen area, the input panel may be placed off the
screen. The change ensure it is always placed within the screen area
using similar math like xdg_popup's slide_y constrain.
The wayland spec is not quite clear about the transforms, but the buffer
transform indicates a transform from wl_surface to wl_buffer or compositor
global coordinate space to composited buffer.
On the other hand, SurfaceItem assumes that the order is vice versa.
`flip-y | rotate-N` transforms are equivalent to `flip-x | rotate-N`.
However, it is not intuitive to express transforms that flip the y axis
via flip-x transforms. This change adds convenience aliases to improve
code readability and keep code intuitive, which is going to be needed in
order to drop TextureTransforms flags.
These can be useful in case a QRect needs to be mapped. One could
convert the QRect into a QRectF and then back to QRect, but given that
these conversion helpers are present in rendering hot paths, it would
be great to be more efficient and also potentially loosing precision
because of floating point arithmetic.
Makes it possible to easily target things in a window near your panel edge,
without bringing up your panel.
The `m_client` condition this MR removes appears to have been added solely to make autohiding panels appear instantly. See c4140d6f4e.

Instead of killing the window without asking, show the kill prompt
like it's done for X11 windows.
The window in question is exported through XDG foreign so the kill
helper can parent itself to it, and an activation token is also provided.
Also, the more contemporary desktop file name is now used for
identification rather than window class.
A no-display desktop file is installed for the kill helper so that it
can get a proper window icon and suppress startup notification.
This makes it consistent with the timeout used on X11.
The current ping timeout was also generally quite short, causing apps
to desaturate for brief moments when they were busy e.g. starting up
or loading large files.
Bouce keys suppresses additional key presses during a given interval

This allows KWin to securely identify the client for a given connection,
without relying on the process name.
This patch does not do anything meaningful with the application ID other
than store it.
This first version does not support kwin restarts, it can come
afterwards.
Testing done:
With latest flatpak, running `WAYLAND_DEBUG=1 flatpak run org.telegram.desktop |& grep security`
shows that flatpak itself bound the security context, and the client did not see it advertised.
It doesn't make sense for a window to become 1x1 pixels small. When we have
server side decorations we also know that the decoration takes a lot of
space, so this commit enforces a bigger minimum size for decorated windows

By default, hyper keys are interpreted as meta keys. However, due to
a Qt bug, it had been incorrectly mapped.
Commit b45b9090c3b66d541f57f8d049c22247f8c115ca in qtbase repo fixed it,
so the test needs adjustments.
Window::acceptsFocus() is not taken into account when a window is
activated using Workspace::activateWindow(). The main reason is because
of different input models on X11.
Instead, Window::takeFocus() should check itself if the window accepts
focus.
