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:
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.

Summary:
All effects which use a (pointer) screen edge now also support the touch
screen edges. These are:
* Cube (cylinder, sphere)
* DesktopGrid
* PresentWindows (current, all, class)

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.

Summary:
The Effect class is extended by three new virtual methods:
* touchDown
* touchMotion
* touchUp
The methods return a boolean value so that the events can be filtered
out. E.g. an effect which has also a mouse grab installed wants to
filter out all events, other effects don't need the events exclusively.
This is a difference to how e.g. keyboard and pointer events are handled.
But is more close to how KWin's internal input event passing works and
makes it easier to get touch event: one does not explicitly has to grab
the events. It's also closer to Wayland where all input events are
available.
As a first example the Present Windows effect is adjusted and allows to
activate windows through the touch screen. As much code as possible is
shared with pointer input.

A QEvent* is passed around, this could also be a QWheelEvent. Only
present windows static casted, all other effects verified.
Documentation is not existing, so we don't know what was intended.
Most of those effects didn't need special screen locking handling on
X11 as they prevented screen locking. On Wayland though, we don't
want the lock screen shown on a cube.

Theory:
----------
because PresentWindowsEffect::screenCountChanged() is shortcut
for "if (!isActive())", but the desktopgrid doesn't call
PresentWindowsEffect::setActive (or at least
PresentWindowsEffect::screenCountChanged), so the effect can
"miss" the increasing screen count change (it sees the signal,
but ignores it) and when desktopgrid calls it, it assumes the
m_gridSizes array is big enough (but it isn't)
Steps:
----------
1. effects are loaded, 1 screen present
2. 2nd screen gets added, but inactive effects ignore that
3. desktop grid gets activated, updates according to screen count,
calls presentwindows for screen #2
4. presentwindows data is only prepared for one screen from step 1
=> BOOM

Without the componentDisplayName the shortcut dialog takes the name of
the application e.g. Systemsettings or "KDE Control Module", but we want
it to be KWin.

This is now crucial, because while before
(the minimized) windows were conditionally
shown, but are now always behind the desktop.
Also, it makes the tabbox more consistent.

The closeview is not hidden because that causes
invalid textures (apparently QML related) and
deleting/recreating causes massive I/O overhead
on effect invocation.
As last resort, the window is "hidden" by moving
it out of the root window geometry.
Jonathan, please RESPIN kwin - sorry for the trouble
... again.

On MacBooks the "Exposé" button is on XF86LaunchA. Let's use it
for activating Present Windows (ALL) as an alternative shortcut.
For non-macbook users this doesn't hurt, for MacBook users it's a
nice touch to have the key working as indicated by the pictogram.
Yes, it's realy Key_LaunchC:
"On X11 this key is mapped to XF86XK_LaunchA key for legacy reasons."

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.

All KCMs and KWin core use the BuiltInEffects namespace to find and
interact with the effects. There is no information left in the desktop
file which are of usage. Thus they can be removed.
This method replaces the X-KDE-ORDERING property in the Effect's desktop
files. This change is a preparation step for integrating the new Effect
Loader which doesn't read the ordering information. Thus it needs to be
provided by the Effect itself so that the EffectsHandler can properly
insert it into the chain.
Also for the built-in Effects on the long run it doesn't make much sense
to install the desktop files. And binary plugin effects will migrate to
json metadata which also doesn't have the KService::Ptr. Thus overall it
simplifies to read this information directly from the Effect.
Most is just switched to the ::read(). That should be enough for all the
Effects which have a KSharedConfig::Ptr underneath. If not we just need
to find a good place to put the reload.
Instead of using EffectsHandler::sendReloadMessage we generate the dbus
interface in each plugin and call the reconfigure slot directly. That way
it's more type safe and we don't need to link kwineffects from the
configs.

There are no advantages for the effects KCM to have all the effect
config modules in one plugin.
By having a plugin per effect we can use the KPluginTrader to easily
find the configuration plugin for a given effect and load it.
To make this possible the following changes are done:
* config_builtins.cpp is deleted
* add_subdirectory is used for all effects which have a config module
* toplevel CMakeLists.txt contains the sources again for the effects
which have a config module, but effects which don't have a config
module are still included and thus the macro is still used
* plugin created for the config module, name pattern is:
kwin_effectname_config
* plugin installed to ${PLUGIN_INSTALL_DIR}/kwin/effects/configs
* desktop file adjusted to new plugin name and keyword removed
* desktop file converted to json as meta data and no longer installed
* Uses K_PLUGIN_FACTORY_WITH_JSON
* Macros for config are dropped from kwineffects.h

Implemented in KWin core to forward to new global shortcut system. This
method should be extended/changed once we go to Qt5/KF5 to make the usage
easier (no more KAction).
Each global shortcut in the effects makes use of this new method.
instead 1/16 of the area, 1/4 of the bigger and 1/32
of the smaller screen/window ratio
(ie. a shaded window would typically zoom to 1/32 of the screen height)

As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects
All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.
During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.
Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.
[1] QElapsedTimer around the loading code, start kwin five times, take
average.
