A scripted component providing:
* ui/config.ui
* config/main.xml
can get a config interface by using the following in metadata.desktop:
X-KDE-ServiceTypes=KWin/Effect,KCModule
X-KDE-PluginKeyword=`X-KDE-PluginInfo-Name`
X-KDE-Library=kcm_kwin4_genericscripted
X-KDE-ParentComponents=`X-KDE-PluginInfo-Name`
`X-KDE-PluginInfo-Name` has to be replaced by the actual value. In case
of a KWin Script the X-KDE-ServiceTypes needs to be:
X-KDE-ServiceTypes=KWin/Script,KCModule
The GenericScriptedConfig tries to identify the package from the keyword
and creates a Plasma::ConfigLoader and loads the UI from the packaged UI
file.
Since the introduction of VirtualDesktopManager we do have a signal
emitted when the desktop layout changes which we can use as NOTIFY for
the desktopGrid properties.

In fact it already used to be a Singleton as there is just one object
hold by the Singleton Workspace. So let's make it a proper Singleton
following our kind of standard approach of having a ::create factory
method called from Workspace ctor and a ::self to get to the singleton
instance.
The main difference is that the activation of an edge is no longer
broadcasted to all effects and scripts, but instead a passed in slot of
the Effect/Script is invoked.
For this the EffectsHandler API is changed to take the Effect as an
argument to (un)reserveElectricBorder. As callback slot the existing
borderActivated is used.
In addition the ScreenEdge monitors the object for beeing destroyed and
unregisters the the edge automatically. This removes the need from the
Effect to call unregister in the dtor.

This rewrite is mostly motivated by the need to handle multi screen
setups correctly. That is have edges per screen and not for the combined
geometry. Also porting from XLib to XCB has been a motivation for the
rewrite.
The design of the new ScreenEdge handling is described in the
documentation of ScreenEdges in screenedge.h.
In addition the following changes have been performed:
* move configuration from Options to ScreenEdge
* add screen edge information to Workspace::supportInformation (obviously
replaces what had been read from Options)
* have Workspace hold a pointer to ScreenEdges instead of an object
* forward declaration of ScreenEdges in workspaces.h, this explains the
seemingly unrelated changes of just another include in some files

The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
The current API call to animate a window does not feel very JavaScripty.
Therefore a new method "animate" is added to the global scope, which
takes a JavaScript object of the following structure:
{
window: EffectWindow, /* the window to animate, required */
duration: int, /* duration in msec, required */
curve: QEasingCurve.Type, /* global easing curve, optional */
type: Effect.Attribute, /* for first animation, optional */
from: FPx2, /* for first animation, optional */
to: FPx2, /* for first animation, optional */
delay: int, /* for first animation, optional */
animations: [ /* additional animations, optional */
{
curve: QEasingCurve.Type, /* overrides global */
type: Effect.Attribute,
from: FPx2,
to: FPx2,
delay: int
}
]
}
At least one animation needs to be specified either on the root level
or in the array of animations. Curve is the only property on root level
which is used in the animations, if not provided.

A script can register a callback through registerUserActionsMenu to be
informed when the UserActionsMenu is about to be shown. This menu calls
the Scripting component to gather actions to add to a Scripts submenu.
The Scripting component now asks all scripts for the actions, which will
invoke the registered callbacks with the Client for which the menu is to
be shown as argument.
The callback is supposed to return a JSON structure describing how the
menu should look like. The returned object can either be a menu item or
a complete menu. If multiple menu items or menus are supposed to be added
by the script it should just register multiple callbacks.
The structure for an item looks like the following:
{
text: "My caption",
checkable: true,
checked: false,
triggered: function (action) {
print("The triggered action as parameter");
}
}
The structure for a complete menu looks quite similar:
{
text: "My menu caption",
items: [
{...}, {...} // items as described above
]
}
The C++ part of the script parses the returned object and generates
either QAction or QMenu from it. All objects become children of the
scripts QMenu provided by the UserActionsMenu.
Before the menu is shown again the existing menu is deleted to ensure
that no outdated values from no longer existing scripts are around. This
means the scripts are queried each time the menu is shown.

KConfigGroup is not the least thread safe and unfortunately
the KServiceTypeTrader::self()->query() will in doubt create
one if the sycoca database was damaged.
