Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.
The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.
Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good
way to load the platform plugin from the tests.

When XWayland associates a Wayland surface with an X window it
sends a WL_SURFACE_ID client message to the window manager.
KWin listens for this client message in Toplevel and provides it
as a member in Toplevel.
This requires KWin to actually start a Wayland server (and XWayland)
to make proper use of the information.
KWin sets a _ORG_KDE_KWIN_DBUS_SERVICE property on the root window
with the name of the DBus service it registered. The type of the
property is UTF8_STRING.

This is going to be a controversal change. It enforces KWin decorations
on all client side decorated windows from GTK+. Unfortunately we are
caught between a rock and a hard place. Keeping the status quo means
having broken windows and a more or less broken window manager due to
GTK+ including the shadow in the windows. This is no solution.
Enforcing server side decorations visually breaks the windows. This is
also no solution. So why do it?
It's our task to provide the best possible user experience and KWin is
a window manager which has always done great efforts to fix misbehaving
windows. One can think of the focus stealing prevention, the window rules
and lately the scripts. The best possible window management experience is
our aim. This means we cannot leave the users with the broken windows
from GTK.
The issues we noticed were reported to GTK+ about 2 months ago and we are
working on improving the situation. Unfortunately several issues are not
yet addressed and others will only be addressed in the next GTK+ release.
We are working on improving the NETWM spec (see [1]) to ensure that the
client side decorated windows are not in a broken state. This means the
enforcment is a temporary solution and will be re-evaluated with the next
GTK release. I would prefer to not have to do such a change, if some of
the bugs were fixed or GTK+ would not use client-side-decos on wms not
yet supporting those all of this would be a no issue.
For a complete list of the problems caused by GTK's decos see bug [2] and
the linked bug reports from there.
The change is done in a least inversive way in KWin. We just check for
the property _GTK_FRAME_EXTENTS and create a Q_PROPERTY in Client for it.
If we add support for the frame extents in future we would also need
this. So it's not a change just for enforcing the decoration.
The actual enforcing is done through a KWin script so users can still
disable it.

Adds NET::WM2BlockCompositing to the Client's properties which allows to
read the state from the NETWinInfo object and get updates without having
to resolve the atom ourselve.

This provides a new protocol intended to be used by auto-hiding panels
to make use of the centralized screen edges. To use it a Client can
set an X11 property of type _KDE_NET_WM_SCREEN_EDGE_SHOW to KWin.
As value it takes:
* 0: top edge
* 1: right edge
* 2: bottom edge
* 3: left edge
KWin will hide the Client (hide because unmap or minimize would break
it) and create an Edge. If that Edge gets triggered the Client is shown
again and the property gets deleted. If the Client doesn't border the
specified screen edge the Client gets shown immediately so that we
never end in a situation that we cannot unhide the auto-hidden panel
again. The exact process is described in the documentation of
ScreenEdges. The Client can request to be shown again by deleting the
property.
If KWin gets restarted the state is read from the property and it is
tried to create the edge as described.
As this is a KWin specific extension we need to discuss what it means
for Clients using this feature with other WMs: it does nothing. As
the Client gets hidden by KWin and not by the Client, it just doesn't
get hidden if the WM doesn't provide the feature. In case of an
auto-hiding panel this seems like a good solution given that we don't
want to hide it if we cannot unhide it. Of course there's the option
for the Client to provide that feature itself and if that's wanted we
would need to announce the feature in the _NET_SUPPORTED atom. At the
moment that doesn't sound like being needed as Plasma doesn't want to
provide an own implementation.
The implementation comes with a small test application showing how
the feature is intended to be used.

By setting the X property _KDE_NET_WM_SKIP_CLOSE_ANIMATION to 1 a window
can request to be excluded from any close animation. This property is
read in Toplevel, so that it is available to both Client and Unmanaged.
If the window has this property set the Scene suppresses the paintWindow
loop of the Deleted. Thus no effect needs to be adjusted. But an effect
using drawWindow directly would still be able to render the Deleted as
there is no suppression.
Furthermore the property is passed to the EffectWindow so that an
Effect can make use of this functionality and not start the animation
in the first place.

The X property _KDE_NET_WM_COLOR_SCHEME can be set on a window and
specifies the absolute path to a .color file describing the color
scheme of the managed client.
The Client reads this property and creates a QPalette from it. If
the property is not set or the value is incorrect, the Client uses
KWin's default palette.
The idea behind this property is to allow an application with a
custom color scheme to tell KWin which color scheme the window
decoration should use. So that the window looks as a solid pattern
again.
During startup we only create the request, the reply will be fetched
once the atom is needed.
To make proper use of this async behavior the creation of Atoms is
moved directly to the claim of the manager selection, so they can be
fetched while we wait for the previous manager selection to give up
on it.
This patch implements an XProperty named _KDE_NET_WM_OPAQUE_REGION
which gives the compositor the information which part of a window
is opaque although it is an ARGB visual. The basic ideas are from
http://www.mail-archive.com/wm-spec-list@gnome.org/msg00715.html
Additionally the patch makes kwin use this information to do a better
clipping in Scene::paintSimpleScreen which should result in a higher
performance.

For a complete documentation of new functionality refer to:
http://community.kde.org/KWin/Shadow
The current implementation includes a new Shadow class and Toplevel
holds a pointer to an instance of this class. The Shadow class reads
the data from the X11 Property. There is one extended class located
in SceneOpenGL to render the shadow.
Compositor is adjusted to include the shadow region into the painting
passes.
Implementation for XRender still missing and Shadow needs to respond
to size changes of the Toplevel to update cached shadow region and
WindowQuads.
the new property name is "_KDE_NET_WM_ACTIVITIES", of type XA_STRING,
and it's a comma-separated list of activity UUIDs.
kwin should respond to other processes changing the activity list for a
window, and filter out any bogus IDs. It also caches KActivityController's
list of activities to prevent dbus deadlocks.

windows while embedding them, allowing KWin to figure out it's being used
and that it's not going away. This hack avoids the reparenting fight
between KWin and QXEmbed where QXEmbed started to loose after the recent
fixes.
In order to make systray really work, QXEmbed still needs some fixes
related to not destroying the embedded window.
