Summary:
It looks like something was forgotten here - there is
a completely empty body for an if statement that checks
whether the pointer is null.
So this might not be the desired way to fix this.
Should m_lastCreatedSettings be instantiated instead?

Summary:
From the rest of this method, it is obvious that m_topLevel can
be null in any part of the method - we are checking against it
being null in a few places in the method - both before and after
the affending lines.
Now, there is one place where the check is not applied, and
potentially calls ->window() on the null pointer.
p.s. If there are more places where kwin does clear_or_something(); return;
it could benefit from introducing on_scope_exit and similar tricks - see
Alexandrescu's 'Declarative control flow' presentation.

Summary:
This is the first change in a refactoring series. The aim is to:
* rename AbstractBackend to Platform
* move backends/ to plugins/platforms/
* don't bind platforms to Wayland only
* provide a platform plugin for "normal" X11
* share more code between X11 and Wayland
This change moves the platform/backend from waylandServer to Application.
The init of the plugin happens directly in the Application from the
KPluginMetaData. There is no need to externally init it and set the
parent.
WaylandServer::backend() currently just delegates to
kwinApp()->platform(), the idea is to drop this method completely.
The test infrastructure is also adjusted to this change.
Test Plan: kwin_wayland still works, all tests pass

This is more a hack than an actual implementation. It just renders
all sub-surfaces after the main window got rendered. But it does not:
* use window quads (e.g. splitting not supported)
* is not combined with rendering of the main surface
* does not support previous pixmap
Still it renders, which is the main goal at the moment.
The rendering is done in a recursive way. For updating the buffer an
important change is done: the buffer is copied into a new QImage on each
change and the differences are no longer painted. This is due to damage
region in a sub-surface tree being basically unknown.
This change introduces a tree for WindowPixmap. A WindowPixmap can
have a parent WindowPixmap and children. Each child represents a
SubSurface and references the buffer of that SubSurface.
The tree of WindowPixmaps is updated each time updateBuffer is called.
If there are new SubSurfaces new WindowPixmaps are created, for removed
SubSurfaces the old WindowPixmap gets removed. Also the ordering is
updated to reflect the current state.
This is currently rather expensive and should be changed to only rebuild
the tree if it actually changed.
Searching for "animation speed" now points to the Compositing KCM, where
the animation speed setting is, instead of the Destkop Effects KCM,
where it was before.
Same for compositing, OpenGL, XRender and video settings

On build.kde.org we cannot use the breeze cursor theme. Instead we have
DMZ-White (debian package dmz-cursor-theme).
This change adjusts the PointerInput test to enforce DMZ-White and uses
SizeAllCursor instead of OpenHandCursor as that one seems to be missing
in that theme.
Hopefully with these changes the test starts to pass on build.kde.org.

Summary:
This reverts commit 14d1fdf63f.
The zoom effect is definitely the wrong way, it's broken (can be
triggered without moving the mouse, expands windows outside of their
allotted area (looks like broken sizing/placement), isn't animated so
feels very choppy, isn't using well-known highlight semantics), the
result is that it feels unnatural and jarring. To be honest, when I
looked at it, I was looking for a bug in the code, e.g. margins not
being taken into account. It didn't come up in me that this could be
wanted behavior, until I read the code.
As to the original commit message: The highlight is useless for this
case, as any window can be dragged or activated, highlighted or not.
What *could* work is to somehow intensify the colors, but that again
would have to be animated, and play well with the ongoing desktop-zoom
animation, the mouse pointer location changes relative to the window, so
it's really complex to get right. I thought of this for a while, I don't
think the complexity that has to be implemented is worth the benefit,
because, what does highlighted really mean here? "window is under the
mouse" isn't a useful metric, as we don't know if the user is changing
desktops or rearranging windows, and "window under mouse" changes
depending on the zoom level, "window can be dragged or activated" also
isn't a useful metric, as I can do that with any window, anyway.
Test Plan: Tested with patch applied, desktopgrid windows don't jump around anymore.

Summary:
While developing support for sub-surfaces it became obvious that there
is a need for visualizing the tree of sub-surfaces.
The surface-tree is a new mode added in the debug console. There are now
two buttons to switch between the default window tree and the surface
tree.
The surface tree is a little bit more basic than the windows tree. The
type of window (whether x11, wayland or internal) is ignored. All windows
build up the top level with the sub surfaces as children.
Each surface is represented by some basic information about it:
* Client (binary path and pid)
* internal surface id
If the surface has a shared memory buffer mapped a scaled down version
is used as the window decoration role.
The model gets reset whenever the tree changes in some way as it's
rather complex to track correctly and well, it's just a debug console.
Currently the tree is not really functional yet as KWin doesn't announce
support for sub-compositor protocol, which is also the reason for lack of
autotests for the model. Will be added once sub-compositor works
properly.

using stack adresses makes it possible (even tough not frequent)
for two animations (onle just killed, one just created) to have

this replaces the id with a global counter, and the

Summary:
Before we were able to render Xwayland windows through the Wayland buffer
we used a xcb-shm to map the window data in the QPainter compositor.
As we don't use that any more and QPainter is not available for X11
anyway we can just drop the code.

Differential Revision: https://phabricator.kde.org/D1173
Summary:
The idea behind the debugging console is to have a feature comparable
to xprop and xwininfo just for Wayland. We cannot have command line
utils as that violates the security restrictions, thus it needs to be
exposed directly in KWin.
The debugging console is invoked through DBus:
qdbus org.kde.KWin /KWin showDebugConsole
This opens a window with a tree view. The DebugConsoleModel which is
used by the tree view groups all windows into four categories:
* x11 clients (that is Workspace::clientList() and Workspace::desktopList())
* x11 unmanaged (Workspace::unmanagedList())
* wayland shell clients (WaylandServer::clients())
* wayland internal clients (KWin's own QWindows - WaylandServer::internalClients())
Each window is a child to one of the four categories. Each window itself
has all it's QProperties exposed as children.
This allows to properly inspect KWin's internal knowledge for windows and
should make it easier to investigate problems. E.g. what's a window's
geometry, what's it's window type and so on.
The debugging console is intended as a developer tool and not expected to
be used by users. That's why it's invokation is rather hidden. Due to
the fact that it's internal to KWin it results in:
* no window decoration
* stealing keyboard focus
* no way to resize, close, move from KWin side
* rendered above all other windows
There is a dedicated close button to get rid of it again. While the
console is shown it's hardly possible to interact with the system in
a normal way anymore. This is something which might be improved in
future.
At the moment the model is able to update when windows are added/removed,
but not yet when a property changes. Due to the lack of interaction with
the existing system, that's not a high priority at the moment, but can
be added in future.
