Currently just opening the Desktop Effects KCM loads QtMultimedia which
in turn loads gstreamer 0.10. If one opens any other KCM in
systemsettings and changes without applying the change, the window
freezes when the warning dialog gets shown, because the warning message
pulls in Phonon with maybe the Gstreamer backend which uses
gstreamer 1.0. This is bad, bad and breaks everything.
By using a Loader the problem scope gets reduced. It still happens but
only if one actually watches a video. Only opening the KCM doesn't
trigger the problem any more.

As we have the split between Effects and Compositor settings nowadays
it's incorrect to have an Compositor related option exposed in the
Effects settings view. Thus the OpenGLErrorView should be removed. As
a nice side-effect that simplifies the main qml file quite a bit by
turning the EffectView from Item into Rectangle.
If it shows that we need the reset GL check in the effects view it would
be better to use a KMessageWidget like in the compositing view.

Introduces partially checked checkboxes for Effects. If an Effect
has an enabled by default function and doesn't have an explicit
value in the config file the checkbox is set to partially. If there
is a value in the config, this will be used.
Clicking on Default will return to the partially checked state.
So far only the built-in effects support the partially checked state
and also the mutual exclusive groups do not support the partial checked
(main reason: RadioButton doesn't support it)

The idea is to warn the user that changing the settings might break
the setup when we know it could be dangerous. The following cases are
considered:
* Scale filter Accurate
* Tearing prevention
* keep window thumbnail always
* EGL if EGL and GLX are available
* unredirect fullscreen not working on all hardware
In addition the OpenGL is Unsafe warning is turned int a KMessageWidget
which is also used for all the other warnings.

This patch applies a common language and type-setting to the
systemsettings modules in kwin.
Considerations:
- The comment field might repeat the name, or give more detail about the
specific settings on this page, this makes sense with how
systemsettings and kcmshell present it
- Mentioning the words settings, configure, options, etc. is avoided --
it is clear from the context that these are settings and options.
- Title-case throughout in line with human interface guidelines, see
http://techbase.kde.org/Projects/Usability/HIG/Capitalization
- The comment ends up being the title, so the
- tech slang is avoided as much as possible, but left in where really
necessary
- I've left the Name field "mostly untouched", as that one is key for
the user to find the right module in systemsettings' icon view and in
the sidebars
The most prominent change is "Compositor" to "Graphics Compositor" (in
the Title field). This is more like a "suggestion", if you don't like
it, I'll take it out again. Reasoning: "Compositor" is a very technical
term, people who know graphics might recognize it. Others might not
understand that "composite" is about graphics -- hence the
specialization. Please enter the commit message for your changes. Lines starting

For a classic user interface like the advanced compositor settings the
good old widgets are still better suited than the new QuickControls.
REVIEW: 118273
We need kdeclarative for i18n support. This needs to be done before we
load the source. By that we don't need to import Plasma.Core which isn't
used by the views at all.
Also we don't need to link twice against declarative.
This ensures that we can tab to the UI written in QtQuick. Unfortunately
it doesn't get initial focus, which seems to be a general problem of
KCMShell (QWidget based KCMs also do not get focus) and it's not possible
to tab out of quick ui again.

This removes all the hacks to add kwin4_effect_ to the name of the Effect
and adjusts the desktop files of the effect configuration's parent
component.
Note: the scripted effects still start with kwin4_effect_ prefix.
REVIEW: 117367
The EffectData in BuiltinEffects is extended by all the data needed for
the desktop effects KCM:
* display name
* comment
* category
* video-url
* exclusive group
* internal
This information is taken directly from the desktop files.
The Built-in effects are now also resolved through the BuiltInEffects
namespace and the KServiceTypeTrader query is adjusted to only find the
scripted effects.
Unfortunately this introduces another round of adding "kwin4_effect_" to
load and save the effects correctly. This will be removed once all KCMs
are adjusted to use the new BuiltInEffects.
The category gets read from the KService and is not translated.
Because of that the KCM needs to do the translation of the categories.
This was also the case in the old KCM.
REVIEW: 117111
Both KCMs had a hard coded default which is obviously bad. Instead we
now calculate a useable implicitWidth and implicitHeight and use this
as the minimum size for the KCM. Which means we need also track changes
to these two root object properties and update the QWidget container
accordingly.

We check whether the effect is scripted and provides a config. If that

BUG: 332186
The model data contains a new role ConfigurableRole. This is used to
decide whether the configure button is available.
The value for the role is set by searching for a KPlugin which has the
effect's service name as X-KDE-ParentComponents. All available configs
are expected to be in kf5/kwin/effects/configs/ and are located through
the KPluginTrader thus binary effect configs need to provide json meta
data.

Sort by:
* category
** exclusive group
*** name
Thus we have an alphabetic order of all categories, in the categories
we have again an alphabetic order of all effects in the same group and
the effects in one group are listed at the bottom of the category.
REVIEW: 116753
The new X-KWin-Exclusive-Category property is read from the service
and provided to QML through the ExclusiveRole. If an effect has such
a role the CheckBox is replaced by a RadioButton. The radio buttons of
an exclusive group take care that only one effect of the group can be
enabled. In addition the radio button acts like a check box. If one
clicks the checked radio button it gets unchecked.
At the same time this change removes the hard coded functionality for
the exclusive group of desktop switching effects. It's all handled
dynamically by creating the ExclusiveGroup when needed. For each
category there can be one ExclusiveGroup.
REVIEW: 116711
For each effect added to the list the KWin DBus interface is queried
for whether the effect is supported.
By default all effects are set to supported, thus if the DBus service
is not around (e.g. compositing disabled) it is assumed that all effects
are supported. In fact it's not possible to figure it out at all.

REVIEW: 116693
Let's try getting the KCM a little bit less scary by properly
hiding everything the user doesn't have to care about. The prominent
desktop effects KCM only contains the list of all the effects which
can be configured and nothing else. Only exception is the disabled
check after failed GL to make this easier for the user.
All the "advanced" settings are moved into a new KCM called
"Compositing" which is put under the hardware component in
systemsettings. This contains all advanced settings including
* whether compositing is enabled at all
* backend
* animation speeed
* scale filter
* unredirect fullscreen
* color correction

A video button is shown if the model provides an url for a video.
If the button is pressed the video element is added in a similar way
to the aboutInfo and starts the video directly. Once the playback
stopped a play again button is shown.
If one clicks the video button again, the video gets hidden.
Room for improvement:
* add a button to open in external player
* ensure video is centered correctly in the list view
Methods added to the Model to map from row index to the backend
identifier and vice versa. That way the Compositing object can do
all the saving and loading.
* all properties extended to be writable and emit change signals
* contains load from and save to config functionality
* Compositing object in qml view is connected to the values of the
components. So changes are directly mapped from UI to business logic
We have an Apply and OK button in the KCModule, so we don't need one
in the view. A change signal is introduced and passed from the individual
items upwards, so that we can connect to it from the C++ side.
When we click into the CheckBox the following effects are being enabled:
*kwin4_effect_desktopgrid
*kwin4_effect_presntwindows
*kwin4_effect_dialogparent
If one of the above effects gets disabled, then the checkbox is unchecked.
Our CheckBox can detect if our effects are enable at the start time.
Only ONE of the following effects can be active at the same
time.
*kwin4_effect_slideEnabled
*kwin4_effect_cubeslideEnabled
*kwin4_effect_fadedesktopEnabled
It's basically a run of the port-cmake.sh script in here, mostly the changes
are the following:
- Using KF5::* targets
- Using the proper macros, following recent developments in frameworks
Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
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.

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.

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.
REVIEW: 104753
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...
