Only used for the delayedMoveResizeTimer as timeout slot. Code is small
so a lambda makes more sense. At the same time the code is slightly
improved to ensure that startDelayedMoveResize is never called while
the timer is already active.
This means that mousePressEvents are now required to come from the
decoration.

two-fold issue
a) setMaximize implicitly sets QuickTileMaximize; setting it again toggles it off
b) setting quicktile mode needs to happen in keyboard mode and thenn the target
still depends on the current windo position, so the untiled window needs to
be in a sane location (while geom_restore will typically be off-screen when
quick tiling by mouse)

For all the decoration updates called from Client into the decoration we
also have a signal being emitted. So turning the pure virtual public

It's not a typical singleton as the ctor is not taking a Workspace* and
needs addtional data to be passed to NETRootInfo.
All the initialization code is moved to RootInfo::create() and the tear-
down code is moved to RootInfo::destroyed(). This includes the support
window which used to be a member of Workspace. It's only needed by
RootInfo, so there is no need to have the ownership inside Workspace.
Instead of using a QWidget we just create a normal window through xcb.
It gets destroyed again in the tear-down code after the RootInfo got
destroyed.
REVIEW: 110238
Main motivation for this change is that it's unhandy to have the class
definition in workspace.h and client.h while the implementation is in
events.cpp although nothing in events.cpp uses it directly.
By getting it out of workspace.h we get the header a little bit smaller
which should improve compile time given that it's included almost
everywhere.
In events.cpp the enum usage is changed to NETWinInfo as that's the class
where they are defined.
RootInfo does no longer hold a workspace pointer. Where it's needed it
uses the singleton accessor of Workspace.

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.

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.

Instead of calculating the screen number each time screen() is invoked,
the screen number gets stored in a private member variable and evaluated

- The setting is ignored, the decoration always gets a "true" for it
- moving a maximized window requires breaking a "strong" snap (1/16 of screen height - unless you use quick maximization)
- all snapping is done towards the client, not the frame
- QuickTileMode is exported to the decoration (just as the maximizeMode) so that it can fix the bordersize alongside that.
Where possible it is changed to Cursor::pos(), where we cannot use the
Cursor class (e.g. Aurorae) we can at least try to limit the usage to
prevent roundtrips to the X server.

The Client::cursor property is changed from QCursor to Qt::CursorShape
and renamed to m_cursor (as all usages are adjusted).
This property is mostly used to define the cursor on e.g. the extended
deco border window. To make this easier a XDefineCursor replacement is
added to xcbutils.h both as a static method and as a member function to
Xcb::Window.
A window can be "maximized" despite it's position is fixed.
Most obvioulsy for a corresponding of "0", but also in other
cases. The window can still be resized, some size is the
maximum one and there's no reason to prevent the shortcut of
this state.

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.
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

Quick tiling/maximizing of Clients is completely independent of the
screen edges functionality. That is it determines the borders itself.
Nevertheless there has been some code still around which interacted with
the screen edges each time a window was moved. This code is completely
useless.
when eg. vertically maximizing a cinemascope video in mplayer
it would horizontally exceed the (16:9) screen, so this
case is translated to a full maximization (effectively binding
the window into screen dimensions)
also, when restoring such video from a horizontal maximization
the restore would usually keep the height (thus breaking the
window aspect) so pass geom_restore -> restore through adjustedSize()

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 two methods:
* place
* placeSmart
have only forwarded the call to the Placement object. Now that Placement
is a singleton there is no need to have them. Every user can call them
directly without going over Workspace.
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.
This implements an optimization similar to one in compiz which defers updating
the backing X window during a window move until the move is terminated. This
helps alleviate some choppiness when using composite + vsync.
REVIEW: 107256
The Compositor class actually behaves like a Singleton so it should be
one. Therefore four static methods are added:
* self() to access the Singleton
* createCompositor() to be used by Workspace to create the instance
* isCreated() to have a simple check whether the Singleton is already
created
* compositing() as a shortcut to test whether the compositor has been
created and is active
The isCreated() check is actually required as especially Clients might
be created and trying to access the Compositor before it is setup.
For most actions where the compositor needs to perform an action
(e.g. scheduling another repaint) signals were already emitted.
So it's easier to just connect the signals to the Compositor
which in turn makes the code much more readable.
All signals are connected from the Workspace when either the
Compositor gets constructed or a Toplevel gets created.
All Workspace functions which were implemented in the file composite.cpp
were moved to an own class Compositor. The header entries were moved as well.
All functions calls are updated.
As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities
There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.

The common usage of stacking order is to loop through

At the moment all entries in the stacking order should

This patch adds a new function Toplevel::addLayerRepaint, that in contrast
to addWorkspaceRepaint does not invalidate every blur texture cache that
overlaps with that region. As the name suggests it rather invalidates the
to the window associated layer at that position. This is especially useful
in the case of move/resize events in combination with oxygen-transparent,
where the altered window is almost always the topmost window and the blur
texture cache of the windows underneath are unchanged.
For the case of fully opaque windows the behaviour of addLayerRepaint
and addWorkspaceRepaint should be same.

Behavior is now like all xinerama related options are enabled.
There seems to be no valid reasons to run multi screen without
xinerama support and even if a user would wish to do so she can
just disable xinerama in xorg.conf.
Furhtermore thanks to KWin scripting it is possible to achieve the
behavior as it used to be with the options disabled. E.g. it is
possible to span a window in fullscreen mode over all screens.
This change is in accordance to the discussion on kwin and plasma
mailinglists:
http://mail.kde.org/pipermail/plasma-devel/2012-January/018542.html
Unlike stated at several places in the code it is not difficult to
setup the connections to all Clients.
It would have been nice if the failed attempts to connect the Clients
would not have made it into the code as emitted signals which are
nowhere used. Not to mention that like in all places the signals to
inform that a state changed were emitted before the state changed was
performed.
