It is more Placement related and does not really fit into geometry given
that it only calls methods on Placement. It probably only was inside
Workspace due to being part of the DBus interface. The DBus methods are
used by external components so it needs to stay.
The DBus Wrapper is now calling the methods on the singleton Placement
directly, so no need in Workspace anymore.
It is not used anywhere inside KWin at all and the DBus method is not
used anywhere inside KDE's repositories (according to lxr). Because of
that marked as deprecated and going to die with Qt 5.

Two new interfaces are introduced:
* org.kde.kwin.Compositing
* org.kde.kwin.Effects
The Compositing interface is generated from scriptable elements on the
KWin::Compositor class and the Compositor is exported as /Compositor.
It provides the general Compositing related D-Bus methods like whether
the compositor is active and toggling and so on.
The Effects interface is generated from scriptable elements on the
KWin::EffectsHandlerImpl class and the instance is exported as /Effects.
It provides all the effects related D-Bus methods like loading an effect
or the list of all effects.
This removes the need to have all these methods provided on the global
org.kde.KWin interface. For backwards compatibility they are kept, but
no longer provided by the Workspace class. Instead a new DBusInterface
is generated which wrapps the calls and delegates it to one of our three
related Singleton objects:
* Workspace
* Compositor
* EffectsHandlerImpl
