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.
Effects can specify their minimum requirements in their
desktop file:
* OpenGL
* OpenGL 2 (GLSL required)
* Shaders (either ARB or OpenGL 2)
The configuration module uses this information in combination
with which backend KWin is currently using. So if e.g. OpenGL
is used and an effect requires OpenGL 2 a detailed error
message can be showed that OpenGL 2 is required.

Instead of getting the information from CompositingPrefs
the running KWin instance is queried through D-Bus.
In general the running KWin should have more information
about whether Compositing will work or not.
This means the kcm no longer has to link OpenGL.

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.
Reduces duplication of settings in different areas and was only
providing a small subset of the possible window switching capabilities.
With BoxSwitch being possible to be rendered as a "normal" window
switcher it does not make much sense anyway.
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.

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.

Also add a usable "doesn't work why" info and WARN! the user about clicking the rearm button.

Move the entire checking into CompositingPrefs

The shadow effect is known to be broken since at least 4.5.
It is unfortunately in a state which makes it difficult to maintain
and the architecture has some serious drawbacks. Therefore it is the
best solution to replace the effect with a new and better
implementation. For more information about the new implementation
please see the discussion on KWin mailinglist:
http://lists.kde.org/?l=kwin&m=129607406517609&w=2
This also "fixes" all existing bug reports about the shadow effect.
Most of the bugs will really be fixed when the new shadow system is
implemented, if not it is a new bug and a new report should be created
for it.
Please excuse that we go this unnormal approach to mark bugs as
fixed with code removal.

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.

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.

Also fixed a little bug in kcmkwincompositing (dropdowns on the general tab were not updated correctly) and cleaned up the code a bit (removed a few unneeded function calls and stale connects).
See the conversation on the mailing list ("Patch for bug 174769", http://lists.kde.org/?l=kwin&m=122696916611602) for further information.
