The usage of geometryShapeChanged() is highly discouraged because it is
emitted when geometry of any kind has been changed, e.g. buffer geometry,
frame geometry, etc.
This change ports DecoratedClientImpl to the clientGeometryChanged()
signal, so the cached client size will be updated only after the client
geometry has actually changed.
Even though the frame geometry and the client geometry have a connection
between themselves, it doesn't mean that the frame geometry will change
if the client geometry has changed and vice versa. For example, it can be
the case when the border size changes. The frame geometry won't change,
but the client geometry will.
In general, similar to the frameGeometryChanged signal, we need another
signal that is emitted when the client geometry has been changed that
can be used then in DecoratedClientImpl.
Unfortunately, 5.19 release is around the corner and I would prefer not
to do any geometry-related changes in order to avoid introducing new
regressions.
In order to fix the propagation of the client size to decorations, this
change ports DecoratedClientImpl from frameGeometryChanged to a signal
that is emitted whenever geometry of any kind has been changed.

Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.

Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...
The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.
This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.
We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

Summary:
In KDE 4, there was a very handy option to disable decoration tooltips.
Decoration tooltips were lost in transition to KDE Plasma 5, and so
the option.
Given that decoration tooltips were brought back to KDE Plasma 5, "Show
decoration button tooltips" option can be still useful for people(like me)
who may wish to disable them because of personal preference.

Summary:
Currently, KWin/Wayland crashes when the compositor is reinitialized.
The reason for that is ShellClient's DecorationRenderer gets destroyed
when the scene is already gone, thus there is no current OpenGL context.
Client works around that issue by destroying scene-specific DecorationRender
in finishCompositing. Such a workaround could be applied to ShellClient
as well, but it would make code more confusing because DecoratedClientImpl
also tries to destroy DecorationRenderer.
A better approach would be to notify DecoratedClientImpl that
compositing is about to be finished, so it can destroy the decoration
renderer when the scene is still alive. This not only fixes the
previously mentioned issue in ShellClient, but also makes code a little
bit tidier.
Test Plan:
Start Plasma on Wayland session, change any compositor settings (e.g.
animation speed).

The change to make maximize mode asynchronous featured the comment

>shouldn't update them till we get a response, but we also need to have
>the correct geometry of the full size window in our request. For now
>they behave as before, updating when we request the change.
We call setNoBorder when we request the geometry but decoratedClient
also checks the maximise mode, in order to follow the scheme above we
need this to operate on the requested state not current state.
X is unaffected.
This fixes the borders being restored correct after maximize/restore.
Test Plan:
Chose a theme with visible borders
Maximised a window and back

Summary:
Thanks to std::bind we don't need that many different slots to setup the
global shortcut connections. Instead we can have one shared
implementation which takes the argument and passes it to the window.
To support std::bind arguments in kwinbindings the initShortcut method
and dependencies are adjusted as well as a new macro is added.
As I don't want to include abstract_client.h in workspace.h a new enum
is created for the quick tiling flags used in Workspace. This caused a
larger refactoring as the change to an enum class also caused quite some
changes.
Test Plan: Affected test cases still pass

This brings back global menu support in KWin.
The DBusMenu infrastructure is different that we just read the DBus service name and
menu object path from the windows rather than passing around window IDs on DBus which
won't work on Wayland.

Summary:
So far whenever the window geometry changed the widthChanged and
heightChanged signals were emitted even if they did not change.
E.g. while moving a window this resulted in the signal being emitted
after every step, although from decoration point of view nothing
changed.
The decoration performed costly tasks like re-layout the window buttons.
With this change the client size is cached and the widthChanged signal
is only emitted if the width actually changed. Same for heightChanged.
This results in the decoration only re-layouting the buttons if the
window is resized horizontally. All other geometry changes no longer
result in a re-layout.

Summary:
From the famous category: "How could that code ever have worked".
Maximized state changes were never passed to window decorations. For
X11 windows the decoration updated the state nevertheless, for Wayland
windows the state did not get updated, thus a maximized window had
borders and was shown with a not maximized button.

If we get a compositingToggled because the Compositor is going down we
don't need to recreate the Renderer as KWin as a whole is going down.
Thus we disconnect the compositingToggled connection when the Compositor
is about to be destroyed.
Summary:
Toplevel::window() is the actual X11 window. This makes it difficult
to use as the generic identifier for both X11 and Wayland. The Wayland
ShellClient already had a windowId() which is now added to Toplevel as
a virtual method. On X11 (Toplevel default) it returns the window().
The method window() now returns XCB_WINDOW_NONE for classes without
the Toplevel::m_client, such as ShellClient. Thus it allows to properly
check whether we are on Wayland or X11.
The code is adjusted to use windowId where a generic id is needed and
to properly check whether the window is valid before using it where
a window() is used.
This also fixes at least one additional unknown issue in
Workspace::setActiveClient
where the windowId of a Wayland client was passed to X11.

Uses the QuickTileMode of the Client to indicate which borders to
remove. This could be extended to be in general when a window borders
the screen edge and not just for quick tile mode.
So far the DecorationRenderer got destroyed and recreated after
the signal compositing toggled was emitted. But that's too late for
e.g. the OpenGL Textures to be destroyed. So lets trigger the destroy
directly in setup/finish compositing. The new renderer will still be
created after the compositing toggled is emitted - we don't want to
have it recreated for the still active compositer type.
NOTE: this is not working completely yet, lots of code is still ifdefed
other parts are still broken.
The main difference for the new decoration API is that it is neither
QWidget nor QWindow based. It's just a QObject which processes input
events and has a paint method to render the decoration. This means all
the workarounds for the QWidget interception are removed. Also the paint
redirector is removed. Instead each compositor has now its own renderer
which can be optimized for the specific case. E.g. the OpenGL compositor
renders to a scratch image which gets copied into the combined texture,
the XRender compositor copies into the XPixmaps.
Input events are also changed. The events are composed into QMouseEvents
and passed through the decoration, which might accept them. If they are
not accpted we assume that it's a press on the decoration area allowing
us to resize/move the window. Input events are not completely working
yet, e.g. wheel events are not yet processed and double click on deco
is not yet working.
Overall KDecoration2 is way more stateful and KWin core needs more
adjustments for it. E.g. borders are allowed to be disabled at any time.
