The wp_viewporter compositor extension allows clients to crop and scale
their surfaces. It can be especially useful for applications wishing to
reduce their power consumption, e.g. video players, etc.
Given that there is no any direct relationship between the surface size
and the buffer size anymore, we have to use specialized helper methods
for converting coordinates from the surface-local space to buffer pixel
space and vice versa.
We currently deal with three distinct coordinate spaces - the window
pixmap coordinate space, the window coordinate space, and the buffer
pixel coordinate space.
This change introduces a couple of helper methods to make it easier
to map points from the window pixmap space to the other two spaces.
The main motivation behind the new helpers is to break the direct
relationship between the surface-local coordinates and buffer pixel
coordinates for wayland surfaces.
windowShown and windowHidden are emitted when the window becomes visible
and hidden, respectively. For example, that can be the case when the
window has been minimized or unminimized. We have to start animations
only when windowAdded or windowClosed has been emitted.

There are several ways to handle unmapping of a wl_surface. The first
one is to destroy the associated AbstractClient instance. The second one
is to transition the AbstractClient in a special state.
The problem with the second approach is that it makes animations such as
fade out more difficult to handle since effects in kwin are geared more
towards the first approach (destroying AbstractClient).
Summary:
This change splits the XdgShellClient class to better match existing
abstractions in the xdg-shell protocol and fix a few issues related to
sending configure events.
In the new client classes, configure events are handled differently.
Instead of blocking configure events, we try to send them as late as
possible. Delaying configure events will let us merge changeMaximize()
for X11 clients and Wayland clients and it also fixes the bug where
we don't send the final configure event when user has finished resizing
a window.
Given that configure events are not sent immediately, XdgSurfaceClient
keeps the last requested frame geometry and the last requested client
geometry.
This patch doesn't intend to fix all issues in kwin's implementation of
the xdg-shell protocol. For example, we still handle surface unmapping
very poorly.
Test Plan: Tests pass.

The text caret tracking feature allows to keep the text caret inside the
zoomed area. It can be especially useful when the zoomed area is smaller
than the text editor.
BUG: 362189
Currently, the focus tracking functionality in the zoom effect does not
work because it relies on kaccessibleapp, which is dead. Luckily for us,
there is a library called libqaccessibilityclient that provides a way
to monitor focus changes.
BUG: 421234
The first time the list in `Add properties` is shown, the position of the first
delegate is miscalculated as (0, 0) and gets hidden behind the section header.
It only repositions when the delegate is destroyed and re-created, for example, when
setting and deleting a filter text. (https://bugs.kde.org/show_bug.cgi?id=422289)
This works-around it by delaying the `overlayModel` filtering until the list is first
shown, which makes the delegate position correctly.
BUG: 421583
FIXED-IN: 5.19
Summary:
When detecting the properties of a window, now it shows and lets the user select the window complete class.
If this property is selected in the overlay, `Window class` takes the whole class value, and the option `Match window whole class` is set.
This adds back a feature the old kcm was offering.
BUG: 421542
FIXED-IN: 5.20
Test Plan:
- `Detect window properties` and pick a firefox window
- The property selector shows: `Window class: navigator` and `Whole window class: navigator firefox`
- Selecting the latter set the properties as per summary

The recommended way to get all EGL extension defines is to include
EGL/eglext.h. EGL/eglmesaext.h is a private header that compositors
should not use.

The bug reporter presents a use case of wanting to run a game and scale
down the result.
For everyone else kwin_wayland nested is just a test tool, so I don't
see any disadvantages.
It could be useful in testing.
BUG: 422141
Since the port to KConfigXT, the placement setting in `kwinrulesrc` now stores the enum value instead of a string equivalent.
The strings and enum values are taken from `placement.h/.cpp`
This was suggested by @zzag in https://phabricator.kde.org/D29790
We don't need to bind disabled outputs to surfaces that overlaps them.
This prevents error down the line and warnings about ignoring surface.enter events with Qt.
