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.

This merge is incomplete and it does not include the review number of
the associated review request. It should have been pushed as a single

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.
Some old restructuring caused -DKWIN_HAVE_OPENGLES to no longer be
passed to the compiler, causing OpenGL-specific code to be built
while the libraries to link it were not available.

This should be the last of the bunch...it was split up so it could be
easily reverted/looked at.
The idea is that all of this will improve searching functionality for a
lot of people using System Settings. That's the hope anyways.
In reality it doesn't help much *yet*, because somebody needs to make
the search functionality search for more .desktop files. It currently
only does main ones afik. I don't know if this is a technical
limitation, or just a minor oversight and perhaps something easy to fix.
Hopefully what I've done is towards a good direction though, of
improving search functionality in system settings...
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.
if both the GLES and EGL libs and headers are found.
Fold all the includes and libraries into 1 varaible each and use those.
in other words, you need to have both OpenGLES and EGL to do a successful build.
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.
