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
