Overall all notifications except compositing suspended by DBus were
configured by default to not have any action. This means all the time we
emit a notification we keep DBus and KDED busy for nothing.
All the cases when a notification is triggered ire also exported to
KWin scripting, so if one really needs to handle something in case a
window is moved, it could be done through a KWin script with much more
context about the event.

BUG: 258097
FIXED-IN: 4.11
The view is never shown or used in any way except to create the
QDeclarativeEngine. So instead of using a view as a wrapper, let's create
a QDeclarativeEngine and a Component and create the script from the
Component.
To have Plasma.Dialog working we also need to add the created script item
to a QGraphicsScene.
Following the approaches of other split out functionality Screens is a
singleton class created by Workspace.
The class takes over the responsibility for:
* screenChanged signal delayed by timer
* number of screens
* geometry of given screen
* active screen
* config option for active screen follows mouse
The class contains a small abstraction layer and has a concrete subclass
wrapping around QDesktopWidget, but the idea is to go more low level and
interact with XRandR directly to get more detailed information.
All over KWin the usage from QDesktopWidget is ported over to the new
Screens class.

This allows to move the slot to reset the decoration when compositing
got toggled from Workspace to DecorationPlugin and the custom cleanup
is no longer needed.

The define KWIN_SINGLETON adds to a class definition:
public:
static Foo *create(QObject *parent = 0);
static Foo *self() { return s_self; }
protected:
explicit Foo(QObject *parent = 0);
private:
static Foo *s_self;
There is an additional define KWIN_SINGLETON_VARIABLE to set a different
name than s_self.
The define KWIN_SINGLETON_FACTORY can be used to generate the create
method. It expands to:
Foo *Foo::s_self = 0;
Foo *Foo::create(QObject *parent)
{
Q_ASSERT(!s_self);
s_self = new Foo(parent);
return s_self;
}
In addition there are defines to again set a different variable name and
to create an object of another inheriting class.
All the classes currently using this pattern are adjusted to use these
new defines. In a few places the name was adjusted. E.g. in Compositor
the factory method was called createCompositor instead of create.

This code never worked (git blame ends at 05507ee2). The event type is
ColormapNotify (32) and not ColormapChangeMask (1<<23).
Nobody noticed for years so it seems like unneeded to be fixed.
