Summary:
Several effects announce a support property atom on the root window. This
change forwards the KWin::Application's signal that the xcbConnection
changed to the EffectsHandler so that the effects can respond to it.
All effects which announce a support property connect to this new signal
and re-announce the property. In case the xcb connection died (future
XWayland crashing case) it is set to XCB_ATOM_NONE by that. In case the
xcb connection got created (future delayed XWayland startup) the atom is
set to the proper value.
In addition all usages of the support properties are guarded, so that no
nonesense actions are performed if the support property is XCB_ATOM_NONE.
Test Plan: Only compile tested as we don't have XFree KWin yet

Summary:
Apparently some old configs made PresentWindows register the top left
corner which does not make any sense as that's not supported by touch.
So to be sure, don't register those edges.

Summary:
The PresentWindows effect does not hide the window to close the selected
window. Instead it moves it outside the visible area. As this is a
"special" KWin window it is on top of the stacking order and needs to be
ignored in the slideback effect.
Instead of doing a special casing for this window the effect is changed
to ignore windows outside the visible area in general. Windows outside
the visible area just don't make sense to block the slideback effect.

Summary:
This patch caputres from the framebuffer using the framebuffer's
geometry, factoring in scale. We then keep the current normal DPI
framebuffer causing it to downsample there.
This is good because:
- it keeps the code very simple
- it's a performance optimisation. Blurring on 4k is naturally more
expensive than at regular DPI. Downsampling keeps it the same - and you
can't see a difference given it's high DPI and you're going to blur it
anwyay.
- it keeps kernel sizes somewhat resolution independent so it will look
just as blurry across multiple screens.
::doCachedBlur still needs doing.
Test Plan:
Ran an app
Ran the kwindowsystem blur test
Observed the right part of the window being blurred

Summary:
glReadPixels needs the correct location relative to the
framebuffer so we need to factor in the scale as well as translation
when going from compositor space.
Test Plan:
Ran the plasma colour picker plasmoid in windowed mode
Clicked on multiple parts of a window
It was right every time

Summary:
Background contrast reads pixels from the framebuffer
we need to convert from compositor to framebuffer co-ordinates
when an output is scaled
Test Plan:
Ran the manual test in kwindowsystem. Moved window over dolphin.

Summary:
There are a few places where KWin needs to read values from kcminputrc.
As I need to add yet another one it makes more sense to properly
structure it like in other cases and have only one kcminputrc hold in
the application. This also allows to better mock the config values in
the integration tests.

Summary:
On Wayland it can happen that a window is still in the stacking order
although it is not visible. This is mostly the case for Plasma windows.
So far the slideback effect did not ignore those windows and as they are
higher in the stacking order than most other windows it blocked the
effect from working once a Plasma panel element got closed.
This change considers a window which has painting disabled in the
stacking order as not usable and thus filters out all those windows.

Summary:
By changing all kcfg to have arg="true" we can pass in the same
KSharedConfigPtr into all effects. This allows to have fake config in
the tests and in the planned effect demo mode.
Also it means that we don't have to hardcode the name kwinrc into the
files. In the configs - where we cannot access the effectshandler - we
use the define KWIN_CONFIG which gets generated based on the compile
time arguments.

All effects which use a (pointer) screen edge now also support the touch
screen edges. These are:

When an application is not responding, its window is desaturated to communicate this.
Also "(Not Responding)" is added to the title bar.

Summary:
The effect unset the WindowClosedGrabRole unconditionally if it does not
manage the window. This results in any grab set by other effects to break.

Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
* swipe up: Desktop Grid
* swipe down: Present Windows
* swipe left: previous virtual desktop
* swipe right: next virtual desktop
The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.
The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.
The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
* started: when the Gesture gets considered for a sequence
* cancelled: the Gesture no longer matches the sequence
* triggered: the sequence ended and the Gesture still matches
The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.
