KWin requires the xcb plugin otherwise KWin crashes when the first
xcb/xlib code is called. First KWin tries to set the QT_QPA_PLATFORM
to "xcb", but that doesn't protect against the command line switch.
Thus KWin also verifies that after constructing the QGuiApplication
the platform name is set to xcb, if not it exits gracefully with a
useful error message instead a crash.
To make that work the KWinSelectionOwner has to be changed to a
pointer and be delayed constructed, otherwise the crash already happens
in the KSelectionOwner.
Furthermore a small sanity check on the plugin is performed by checking
whether KWin can get the XDisplay from the QPA. If not it means that the
QPA plugin was compiled with -no-xcb-xlib which KWin doesn't support, it
still uses XLib at various places. If KWin doesn't get the Display, it
exits gracefully with a clear error message.

Picked Wayland by default instead of X11 causing KWin to abort
startup if there is no Wayland backend.
Important lesson: test your changes also on X11 and not just on
Wayland!
In the Wayland world we need to have a compositor. This means we have to
enforce that the compositor is running. If the setup fails we have to
quit, because it doesn't make any sense any more to be running.
A new method requiresCompositing() is added to the Application. If it
returns true the useCompositing option will always return true and the
unredirect fullscreen option will always return false. That way
compositing is enforced at startup and cannot end by unredirecting.
In addition this method is checked if actions are performed which would
suspend compositing. E.g. the shortcut to toggle compositing. Restarting
the compositor is still possible in order to change the selected
compositing backend without a restart. But if it fails KWin will quit.
Returns true if the OperationMode requires KWin to composite to a
Wayland surface. This replaces the checks for the WaylandBackend or env
variable used so far in the construction of the Scene.
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.
Instead we generate an export header for kdeinit_kwin and use it
to declare the KWIN_EXPORT. With this change our libs don't include
any KDE4Support headers any more. One step closer to no KDE4Support.
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.
The main purpose of the opengl testapp was to set the environment
variable LIBGL_ALWAYS_INDIRECT if direct rendering is not supported
before glx gets initialized.
With Qt5 we may no longer set this environment variable. QtQuick
requires direct rendering. On IvyBridge QtQuick is crashing if the
variable is set. Thus we are no longer allowed to set it and thus the
complete test becomes pointless.
The test app basically whitelisted most drivers anyway, the only
drivers which were problematic are the proprietary Catalyst drivers.
It that's still a problem we can also disable OpenGL compositing on
those drivers through the recommendation in the GLPlatform.
This also means that the KWIN_DIRECT_GL variable is no longer useful.
The variable is set not from config nor anywhere else when kwin is
started through ksmserver by startkde.
In addition the KGlobal implementation is twisted compared to the kcminit
config behavior (the config value defaults to true, not false - ie. if the
variable isn't set (by kcm init) it's reasonable to assume true either.
Therefore and in alignment with PW/2, the environment is read directly and
on absence resolved to "true".
To control the behavior, please export KDE_MULTIHEAD=true/false before starting KWin
(eg. in /usr/bin/startkde)

During startup we only create the request, the reply will be fetched
once the atom is needed.
To make proper use of this async behavior the creation of Atoms is
moved directly to the claim of the manager selection, so they can be
fetched while we wait for the previous manager selection to give up
on it.
The crash count checking does not depend on whether or not we will
be able to claim the window manager selection. As claiming the selection
can take up to one second we should try to get as many checks which do
not depend on it out.
KSessionManager is deprecated and there is no replacement yet. So
let's get rid of the warnings for now. Needs to be re-added once
there is a working QSessionManager again.
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.
Forwards all xcb events to Workspace::workspaceEvent() which got changed
to process xcb events instead of XEvents. So far all handling is
disabled. Will be re-enabled step by step in the following patches.
We need to connect to this signal instead of waiting for it to time out.
This means we are already starting the window manager while it might be
that we fail.
* "" 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.
Messages in scripts are written to kwin_scripts.pot, messages in
scripting are written to kwin_scripting.pot. The cataloges are loaded in
the configuration interfaces and in main kwin.

Code section had been in an #ifndef NDEBUG which is the reason why I did
not find the usage of Extensions there and why it always compiled
successfully.
Some data elements which got dropped needed to be added again like a name
for the extension and errorBase, etc.
Sorry for the inconvenience of a semi-broken master.
This got used to check whether the session is being restored and only if
the session was not being restored the multi-head checks used to be
performed. Since 299a78772b823d28cf3c48aff696cfb978d0ae7e the multi-head
checks are no longer bound to not restoring the session which obsoletes
the remaining checks.

A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

Options loading is split into three parts:
* reparse configuration
* loading of non-compositing related options
* loading of composited related options not needing CompositingPrefs
At startup the reparsing of configuration is done through a Thread
to gain a little bit of less waiting.
Before something else accesses the KConfig for the first time we
wait for the thread to finish and perform the other two loading
operations of Options.
The settings depending on CompositingPrefs will only be invoked
if a compositor is going to be needed.

It is possible that adding this build option broke the Scripting
component. This is something that should not happen. Unfortunately
by just ifdefing everything scripting related with scripting enabled
we have build errors. These are caused by the fact that the scripting
code includes e.g. client.h through "./../client.h". At one offending
place I changed that to "client.h", but there is also a client.h in
the scripting directory.
The includes and naming of the scripting files clearly have to be fixed!
Some applications like kwin suffer from heap fragmentation
when using the raster graphicssystem. This patch provides a function
that forces glibc to shrink the heap more often.
Now 5*pagesize(=20kB on a typical x86 system) of unused space at the
end of the heap are enough to force free()
to release this space. The default threshold is 128kB which is too much
for an average kworkspace application.

With raster a QPixmap is no longer a XPixmap which fails all code
which assumes that an QPixmap is an XPixmap. Depending on were in
the codebase we either convert such pixmaps to images (OpenGL) or
create a XPixmap and use QPixmap::fromX11Pixmap to get a "real"
pixmap.
It is possible that there are more code pathes were we would need
a XPixmap. Currently tested is basic functionality of no-compositing,
XRender compositing, OpenGl/GLX and OpenGL ES/EGL compositing.
For OpenGL compositing raster might result in performance improvements,
for XRender it is possible that there are regressions when using raster.
By default KWin uses whatever is the default of the system, so we just
no longer enforce native.
Of course it is a bad idea to use graphicssystem OpenGL. As that
is broken anyways in Qt, we do not check for it.
Many thanks to Philipp Knechtges for bringing up the issue, convincing
me that we need it and providing most of the patch.

Merging scripting from

svn path=/trunk/KDE/kdebase/workspace/; revision=1177865
to a branch, but instead committed to the trunk. Well, the trunk was
broken because not all files were committed and hence anyone who checked
out of the trunk during this time could not have built kwin.
From what I can gather, the trunk has been broken for around 45 minutes
now. I didn't realize all that while that the trunk was broken. I
apologize for the inconvinience and I deeply regret my actions which
were clearly not well-thought.

kwin --stest
