Main motivation for this change except the fact that it doesn't belong
into Workspace is that the screen edges got updated from within setting
the desktop layout which got removed with the introduction of the
VirtualDesktopManager.
The ScreenEdge now keeps some state to be able to correctly unreserve the
electric borders when changes in the configuration are performed. There
is still room for improvement as there are still some deep function calls
from within reconfiguring in Workspace.

Most recently used virtual desktop chain is only used in the context of
TabBox and therefore moved into this namespace. KWin uses one desktop
chain for each activity. This is mapped by having multiple DesktopChains.
In addition there is a DesktopChainManager which contains all those
chains which are identified by a QString.
The manager gets connected to the signals emitted by VirtualDesktopManager
for changes in virtual desktops and to signals related to Activities
emitted by Workspace. This means the manager is rather generic as it does
not depend on any other components.
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 client can still live on and emit stuff, but the
compositing has been fininshed for it, so the effect window is NULL

Aurorae Themes can make use of the extended borders feature to allow
resizing outside the window decoration area. So far only Plastik makes
use of it in the Tiny border case.
This should be extended in future by adding generic NoSideBorders and
NoBorders sizes as used by Oxygen.

Let's assume a user knows what she is doing when she selects kwin_gles
instead of kwin. Also in gles there is no fallback to OpenGL 1 possible
so blocking is not the proper solution in the first place.
