The implementation consists of a class in libkwineffects.
There are some slight modifications in the compositor. Regions for
different outputs are drawn at different times.
Currently only per output color correction is implemented. However, the
grounds are prepared for implementing per window color correction
easily.
The ColorCorrection class needs to communicate via D-Bus with a KDED
module, KolorServer, which is a part of KolorManager.
The only visible part for the user consists of a check box in the
advanced tab for the compositing KCM.
The actual correction is done by injecting a piece of code in the
fragment shader, code that does a 3D lookup into a special color lookup
texture. The data for these textures is obtained from KolorServer. All
D-Bus calls are async.
As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities
There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.

BUG: 303090
FIXED-IN: 4.10
REVIEW: 105546
There is no need to have it driver specific any more.
All drivers seem to support it (only Intel had been
opt-ed out without any apparent reason shown in commit log).
This was the last driver specific setting which means that
the method applyDriverSpecificSettings() got dropped from
CompositingPrefs.
Strict binding follows the driver (GLPlattform) unless
the user has a config value specified in the kwinrc.
For this a new property is added to Options to indicate
whether strict binding is user defined or follows the
driver. In case of driver the strict binding option is
set when OpenGL compositor starts up.
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.

Use setter when changing a value to ensure that signal gets emitted

Behavior is now like all xinerama related options are enabled.
There seems to be no valid reasons to run multi screen without
xinerama support and even if a user would wish to do so she can
just disable xinerama in xorg.conf.
Furhtermore thanks to KWin scripting it is possible to achieve the
behavior as it used to be with the options disabled. E.g. it is
possible to span a window in fullscreen mode over all screens.
This change is in accordance to the discussion on kwin and plasma
mailinglists:
http://mail.kde.org/pipermail/plasma-devel/2012-January/018542.html
Due to changes in build system we have always either OpenGL or OpenGL ES.
This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the
effects the define is kept as KWIN_HAVE_OPENGL which can be used in
future to build also an XRender only effect system.
The advanced compositing option "direct rendering" could only
correctly be honored in the case of proprietary NVIDIA drivers.
In all other cases playing with the setting was most likely
harmful as it could result in inconsistent states and the
option not to be honored at all.
This patch resolves this issue by moving the detection whether
to use a direct rendering context completely into the hands of
the set environment variables or the helper program:
* if LIBGL_ALWAYS_INDIRECT is set, we use an indirect context
* if KWIN_DIRECT_GL is set, we use a direct context
* if none of the two are set, we use the helper program, if it
returns 0 we create a direct context, otherwise we set
LIBGL_ALWAYS_INDIRECT and create an indirect context
If a user really wants to influence the behavior the
environment variables can be used.

Removes the last bits of the self-check at compositing startup.
It seems like they were only added to XRender because they were
in OpenGL and there they are not available for quite some time.
Also removes the now obsolete disable functionality checks from UI.

Drawbound was nowadays only used when compositing is disabled.
For the composited case, the drawbound was replaced by the resize
effect and in fact we should always just use the resize effect.
REVIEW: 101411
Well we don't have another choice if half of the drivers crash kwin
whenever you watch a fullscreen flash video or use a screen saver.
Unredirect Fullscreen Window was quite useful in case you used
to play heavy OpenGL games, but pretty useless for anything else.
For the game and hd video usecase we nowadays have the better way
of really suspending compositing (either by the client indicating or
with a window specific rule). The plus of suspending compositing is
that the driver doesn't crash.
And yes we are "supposed" to no longer workaround driver bugs.
Good joke, I like to redirect my inbox to everyone who things we
are not allowed to workaround driver bugs.
CCBUG: 252817
Second part of cleaning up the lib directory: the effects library
now lives in libkwineffects/ directory.
For existing effects nothing changes as the install path is unchanged.
The change obsoletes the lib/ directory.
As glplatform.h has not yet been exported I dared to export it and
adjust the places where it is used.

Our primary target is Texture From Pixmap and it is supported
by all important drivers nowadays. If a driver is not able to
support TFP using OpenGL at all is probably no good idea and
XRender is more suited.

This commit merges the kwin-tiling branch. Ideally it shouldn't break anything and add a few features ;-)
It was applied as a patch. Do not attempt to merge the branch directly, it has a few issues.
This feature is currently experimental, although it hasn't crashed in quite a long time. It lacks some features and probably leaks some memory. Fixes will be on the way.

like it was before. This makes it possible to enable compositing again on my
R600 hardware and other hardware that is not explicitly known to work.
I also think that CompositingPrefs::enableCompositing() is a (really) bad name:
it's not about user preferences and it's not definitive. So what about
CompositingHardware::isKnownToWork()?.

from David. Due to an elusive bug somewhere in kdelibs we have not been
able to find out how to fix the issues that some people were having.
There seems to be a race condition as I cannot reproduce at all, David
can reproduce sporadically and some reporters can always reproduce.
This commit attempts to also keep the code style changes that were made
at the same time as the original commit as well as some minor bug fixes
that were made between then and now. Hopefully I didn't miss anything.
We will be revisit this in KDE 4.3.
