This enum describes how KWin is operating with the available windowing
systems. By default KWin is using the OperationModeX11, but if the
Wayland backend gets started KWin is using the OperationModeWaylandAndX11
This will be extended in future when XWayland and Wayland only become
viable options.
This compositor uses only the QPainter API to perform rendering. The
window's X Pixmap is mapped to a QImage using XShm. As rendering backend
a QImage is used.
The new compositing type "QPainterCompositing" is introduced. Effects
need to be adjusted to explicitly check the compositing type and no
longer assume the compositing type is XRender if it's not OpenGL.
This compositor can be selected with using "Q" as the value for
KWIN_COMPOSE env variable or setting the config value to "QPainter".
The GUI is not yet adjusted to select this compositor.
The QPainter scene provides currently the following features:
* 2D transformations (translation and scalation)
* opacity modifications
* rendering of decorations (new PaintRedirector sub class)
* rendering of shadows
* rendering of effect frames
* rendering to a Wayland surface
The following features are currently not provided:
* saturation changes
* brightness changes
* 3D transformations
* rendering to X Overlay window
* offscreen rendering (e.g. needed for screen shot effect)
* custom rendering in the effects to the current back buffer
The backend gets created by Workspace, but only if the environment
variable WAYLAND_DISPLAY is set.
Because of that the egl wayland backend does no longer create the
backend, but uses the already created one.
The ActionCollection was only used for two features:
* setting the object name
* finding the action for retrieving it's shortcut
This can also be achieved by just setting the object name and searching
for the children of the Workspace singleton.
This looks mostly like dead code. The change got only emitted by the
KCMKeyboard on save. In ancient times this seems to have caused to
re-read the global shortcuts. Code got commented out during KDE4 times
and after several code refactors all that was left of it was discarding
the user actions menu.
Replaces one usage of KGlobalsettings. It might be a good idea to
move the connect into libkdecoration or into the options as it looks
like there is no need to reconfigure everything just because the fonts
changed.
Replaced by KWIN_VERSION_STRING where useful. Support information
no longer contains the SC version number. We have to see whether
there will be a useful framework based platform information.
A factory is supposed to emit this signal whenever the decorations
need to be recrated. The DecorationPlugins inside KWin Core connect
to the signal and recreate the decorations.
This signal is supposed to replace the reset method which encoded
this information in the return value and which is already ignored.
The changed mask is going to be replaced by more specific signals so
we don't need to calculate the change mask in KWin core anymore.
We still need to call reset in the decoration plugin to check whether
a new decoration library needs to be loaded.
There used to be an own action collection in KDE 3 times for the
block global shortcuts shortcut. But the code ws disabled and by
that I didn't see it during removing the global shortcuts blocking.
And it explains why the global shortcut blocking didn't work.
Done in one step as it requires changes which are better suited with a
QApplication.
To not need to parte the QCommandLineParser around the needed arguments
are added to the KWin::Application through setters and the crash count
is available through a static getter/setter pair.
Wrapped in xcbutils.
In addition the check whether another WM is running in main.cpp is
improved by doing a checked request and directly checking for the
error. If there is an error, KWin puts out an error message and
quits.
Client::releaseClient() deletes all Client objects
referenced by stacking_order, thus those pointers
dangle and everything trying to touch it died an ugly death.

Using a QTimer to move the resize/move related code to the end of the
event queue. In case there is another motion event in the queue it will
cancel the timer.
* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
Qt 5 only supports raster which means our pixmaps are always non native,
so we don't need the Extension information any more and can drop all
special code handling for mapping a native QPixmap to an X11 pixmap.
fixing bug by deferring the deletion and removal of the
deleted to the next event cycle had the side effect that
this now happens in the event cycle of the compositor
restart, which was deferred to avoid precisely that...
so the test is now moved to the removal of the deleted
which got an additional flag wasClient to avoid calling
this action for each and every tooltip (and might be usable
elsewise)

This shortcut did not make any sense to me, because you could block the
global shortcuts for KWin, but not re-enable them again. So once blocked,
it was blocked for ever till kwin --replace &.
This is in opposite to the commit message which introduced it
(see BUG 108961).

Unfortunately only information available through the factory can be read.
As Factory is not a QObject we cannot use the Q_SLOT trick to get further
information dynamically from the loaded decoration plugin.

Split out the default and installed colormap from Workspace and put them
into an own class Colormaps.
The method updateColormaps is replaced by a slot update in Colormaps and
activeClientChanged signal is connected to this slot.
At the same time the colormap related code is straight forward ported to
xcb.

It's not a typical singleton as the ctor is not taking a Workspace* and
needs addtional data to be passed to NETRootInfo.
All the initialization code is moved to RootInfo::create() and the tear-
down code is moved to RootInfo::destroyed(). This includes the support
window which used to be a member of Workspace. It's only needed by
RootInfo, so there is no need to have the ownership inside Workspace.
Instead of using a QWidget we just create a normal window through xcb.
It gets destroyed again in the tear-down code after the RootInfo got
destroyed.

Main motivation for this change is that it's unhandy to have the class
definition in workspace.h and client.h while the implementation is in
events.cpp although nothing in events.cpp uses it directly.
By getting it out of workspace.h we get the header a little bit smaller
which should improve compile time given that it's included almost
everywhere.
In events.cpp the enum usage is changed to NETWinInfo as that's the class
where they are defined.
RootInfo does no longer hold a workspace pointer. Where it's needed it
uses the singleton accessor of Workspace.

Workspace is hardly interacting with Rules and all the Rules related code
is already in rules.cpp. This highly qualifies to move all the code out
of Workspace and improve the names.
