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.

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 is used by people with motor impairments or bad keyboards
It works by remembering the last input timestamp for a key
If an event's timestamp is too close to the last timestamp for that key the event is rejected
