Add an option to kcmcompositing in the 'Advanced' tab, to enable or
disable color correction. It is specified that it's experimental and it
needs Kolor Manager.
Before painting for a particular screen, ColorCorrection::setupForOutput
should be called.
A screen property is added for WindowPaintData.
In kwinglutils, The fragment shaders are intercepted before being
compiled and they get a couple of lines of code inserted in order to do
the color correction. This happens only when color correction is enabled, of
course.
For D-Bus communication with KolorServer, everything is async.
The implementation basically manages a set of color lookup tables for
different outputs and for different window regions. These are taken via
D-Bus. Each lookup table has around 700 KB.
This commit reintroduces the changes from the former merge with the
"color2" branch. In this form, it can be easily reverted.

SceneOpenGL turns into an abstract class with two concrete subclasses:
* SceneOpenGL1
* SceneOpenGL2
It provides a factory method which first creates either the GLX or EGL
backend which is passed to a static supported() method in the concrete
sub classes. These method can test whether the backend is sufficient to
be used for the OpenGL version in question. E.g. the OpenGL 2 scene
checks whether the context is direct.
The actual rendering is moved into the subclasses with specific OpenGL 1
and OpenGL 2 code. This should make the code more readable and requires
less checks whether a Shader is bound. This is now known through the
Scene: the OpenGL1 scene will never have a shader bound, the OpenGL2 scene
will always have a shader bound.
To make this more reliable the ShaderManager is extended by a disable
method used by SceneOpenGL1 to ensure that the ShaderManager will never
be used. This also obsoletes the need to read the KWin configuration
whether legacy GL is enabled. The check is moved into the supported
method of the OpenGL2 scene.
REVIEW: 106357
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
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.
REVIEW: 104562
Use setter when changing a value to ensure that signal gets emitted
and the option dependencies are applied.
Also use the default values as provided by the static getters.
REVIEW: 104561
For each option a static getter is introduced returning the
default value.
Some GL compositing related options do not have a proper default
value but depend on the actual GL driver. Sane default values are
assumed for those options.
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
Since the funtionality of TopMenu did no longer work in KDE4 this feature was
removed from Workspace. Every reference to it was removed as well as commentaries
and documentation.
REVIEW: 101485
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
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 should improve v'syncing, maybe v'synced "smoothness"
remaining and exposed issue are "dirty textures" w/o damage events (see the requst description)
can be diminished by increasing MaxFPS above the fastest update (or shadowed below the slowest one)

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.

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.
