Summary:
This dbus method is intended to be used by the kwin rules dialog. KWin
can pass the internal id to the rules dialog through a command line
argument (or similar way) and the dialog can query the information
through the dbus call for the provided id. Thus it's possible to
implement one way to query the information which works on both X11 and
Wayland without any windowing system specific functionality.
Test Plan: See new added integration test

Summary:
This document describes my own practices on how I develop and work on
KWin. Since we have nested KWin/Wayland my ways of developing completely
changed. Especially since it's possible to run without installing. Due
to that I thought it's a good idea to document how one can easily build
and run KWin.
Why a new document in the source tree instead of the wiki?
The main reason for using a wiki was that it allows to format, to link,
etc. This was prior to markdown and prior to code hosting places like
github or phabricator rendering the markdown pages. Given that I think
the information belongs in the repository and not in an external wiki.
Why not fix the existing page?
Our documentation on the wiki is quite outdated:
* Qt 4 based
* only X11
* reviewboard
* information about file structure which does not match reality
Especially the last point is where I think we need to do a clean cut and
just drop such information. Documentation about code belongs in the code
and not detached in wiki. It will outdate.
How to prevent this document will not become outdated?
Of course difficult. But I tried to not describe anything which might
change, such as file layout, etc.

Summary:
This file has not been tracked for years. Nobody added when new features
were added, when existing code was broken, etc. E.g. none of the changes
since EWMH 1.4 is listed, none of the kde specific extensions is listed.
The document does not contain anything about Wayland protocol support.
I would not trust this document at all to say whether KWin is compliant,
but would check the source code. And after all most of the compliance is
done in KWindowSystem and KWayland, not in KWin.
Also the document lists compliance of other non-KWin elements such as
Qt, kicker (kde 3 thing, not application launcher), etc. This shows it's
also something which doesn't belong in KWin's source tree.

The idea behind this autotest is to verify that different window
open/close animation effects behave similarly.
Currently, we just check whether Fade/Glide/Scale effect tries to animate
the appearing or the disappearing of toplevels. In the future, the
autotest will be extended to verify that there are no conflicts between
those three effects and the Login/Logout effect, etc.

This change removes a small difference between X11 and Wayland clients.
It ensures that all transients are sent to the same desktop as the main

sendClientToDesktop which supports sending to the same desktop so that

Summary:
This command line option is useful for KWin in embedded use case. That
is when KWin is just used as a compositor for one application instead of
a complete desktop environment. In such a setup global shortcuts are not
wanted and interfere with the application. E.g. one does not want Alt+F4
to close the window, that would render the system unusable.
This change introduces a command line option and disables the following
event filters and spies:
* global shortcuts
* modifier only shortcuts
* terminate session
* virtual terminal switching
* screen edges
KGlobalAccel still gets inited, otherwise the (non-functional) binary
would be launched when KWin registers it's global shortcuts.
Test Plan:
New test added based on existing tests for the global
shortcuts, ctest passes

Summary:
213239a0ea tried to address the case when
a wayland client gets shadow after it was mapped, but because of poor
testing from my side, another bug was introduced. If a decoration tooltip
or the user actions popup is shown, then in some cases it can be blank.
Usually, SurfaceInterface::shadowChanged proceeds SurfaceInterface::sizeChanged,
so when the shadow is installed, window quads cache is rebuilt. But
because shell client already knows the geometry of the internal client,
goemetryShapeChanged is not emitted, thus the cache is not updated.
It would be better just to invalidate the cache when the shadow is
installed, uninstalled, or updated. This reduces the number of
unnecessary invocations of Scene::Window::buildQuads and also moves
handling of the window quads cache away from the Shadow class.

* Minimal find Toplevel operations on window stack.
* Reduce code duplication in pointer and touch child classes.
* Reuse tracking in drag operations.
* Allow direct usage of Wayland input interfaces for decoration and internal

* Update touch focus on external events like VD switches correctly.

For supporting Wayland windows in the kwin_rules_dialog we need a way to
pass a window id for Wayland windows to the dialog. This id needs to be
sent to the dbus interface to query window information just like the
interactive query. For Wayland windows we don't really have a window id
and it would require to also pass the windowing system to
kwin_rules_dialog and back through the dbus interface.
To not complicate things this change introduces a windowing system
independent id based on UUID. This could in future also be used
internally for areas where it's window id based and used in both
windowing systems.

Summary:
One of the things I dislike most about our virtual keyboard integration
is it's size. It's at least on my system covering too much vertical
space. Unfortuantely the keyboard API does not offer a way to control
the vertical space - one can only control the width. Thus it's also not
possible to just provide the keyboard in the optimal size.
This change tries to address the problem by adding a resize button. When
pressed one can dynamically decrease and increase the width of the
keyboard and thus also the height.
The button is added to the top/right corner. Ideally it would be added
to the symbol button row, but either I couldn't find the appropriate API
hooks or it's not possible.

The idea of opening the compositing kcm was to show a warning. But that

* use dbus call to already open kcm
Neither of the two ways is working. The kwincompositing doesn't parse
the arguments and the dbus interface doesn't exist any more.
Following the advice to remove functionality nobody noticed that it is
broken, this is removed with this change. This probably broke with
