Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
This change removes all traces of wl-shell in the test suite. That's a
prerequisite for dropping wl-shell support in KWin.
Given that wl-shell and xdg-shell are not interchangeable, some tests
were removed and initialization sequence in some tests was adjusted.
The most notable change is ensuring that each plasmashell window sets
its role and initial position before committing the surface. Setting
those properties before the first surface commit is important because
our window placement code needs to know window type in order to
avoid maximizing panels, popups, etc.

Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.
A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.
The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

We have lots of inconsistency at the moment in CMakeLists.txt files. Most
of it is due to kwin being a very old project. This change hopefully fixes
all of it.
Summary:
In order to pick the next client to activate we traverse the stacking
order from bottom to top and assign to each client a score. The client
with the best score will be activated next. Function that assigns score
bases its decisions purely on geometry. This may backfire if there are
couple maximized or fullscreen clients on the screen - we'll activate
the bottom-most client.
This change toggles direction we traverse the stacking order. If there
are several clients with an identical score, then prefer the top-most
client, the one that the user most likely sees at the moment.

Summary:
When ShellClient tears down, it needs to access RuleBook in order to
discard temporary rules. The problem is that WaylandServer outlives
Workspace and therefore so does ShellClient.
We can't guard against the case when RuleBook::self() is nullptr as it
is vital to discard temporary rules.
This change adjusts termination sequence so all shell clients are
destroyed before Workspace(and thus RuleBook) is gone.

Doxygen comments with this style look balanced and neat, but many people

This change switches doxygen comment style in KWin to a more traditional

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

Summary:
Currently, the Night Color manager supports three operation modes:
* Automatic: in this mode, screen color temperature is computed based on
the current position of the Sun. In order to calculate sunrise & sunset
times, the manager needs coordinates of the user, which are provided by
Plasma;
* Location: this mode is very similar to the Automatic, except one minor
detail: user needs to provide his/her/their location. This mode can be
very useful if coordinates provided by Plasma are incorrect;
* Timings: unfortunately we can't compute timings of the Sun for people
living near Earth poles. This mode allows the user to specify timings of
sunrise and sunset as well the transition time.
This change introduces another mode, called Constant. With this mode the
screen color temperature is constant throughout the day. The new mode
can be useful for people wishing constant screen color temperature or
just for people living near Earth's North or South poles.

needs to be guarded.
Is there a more general approach to it? Always guarding is ugly. Also when

Since d51b8dc093 the test fails on CI, apparently because we test with

the window geometry and still be on the border if borders exist, otherwise
not.
For now fix it by checking if there are borders or not and then test
accordingly. But long-term we should test both cases and besides not rely on
external decorations for our test, instead use a fake specific for our
integration testing.
Summary:
So far KWin didn't send axis_source, axis_discrete, and axis_stop. Even
though most of those events are optional, clients need them to work as

scroll events when the compositor sends axis deltas greater than 10, etc.

Kwin has the same concept of geometry for both window management, input
and rendering.
In order to approach this in a way that does not risk any regressions
with kwin's current structure AbstractClient::geometry remains the
canonical source and we handle the window within that internally within
ShellClient treating the windowGeometry as a set of margins from this.

This code adds the missing surrogate handling, and (to fix both issues), also
