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
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.
It seems not all Qt installs will automatically #include QElapsedTimer
from QtCore/QTimer, this caused a build failure on my system and on a
RHEL 6.2 VM I've been testing on.
Checking the Qt docs, QBasicTimer also has a separate include so
although this didn't cause a build failure, I've thrown in its
separate #include as well. I have not checked for other #include errors,
and a very quick search on b.k.o for bugs mentioning "build" did not
return any bugs to close.
I'm pretty sure this build failure applies only to master but I haven't
checked thoroughly.
using color.rgba() for an invalid color corresponds to solid black, which in turns conflicts with the cache
value for such color. We use "transparent black" instead.

the geometry setting needs to happen out of recursion,
has to be smarter for unmaximizing and also no real
place in TabGroup - the client is no longer tabbed thus
it's not the groups task to manage it's geometry.

The refactoring of Compositor starting with b1739c3 caused some
regressions due to variables in Workspace and Compositor not
being initialized. Furthermore there was a boolean logic error
in PaintRedirector causing the decorations not to paint.
BUG: 305875
Adding a KConfigXT xml file and an ui file to configure the QML
variant of Plastik.
Currently supported options:
* title alignment
* title shadow
* animation of buttons
Missing option:
* colored borders
If the decoration package contains a ui file in ui/config.ui and
and KConfigXT xml file in config/main.xml the configure dialog
is extended by the custom values.
For this the ui file is loaded and included in the dialog's
layout. To make this possible the AuroraeConfigForm is changed
to a VBoxLayout containing the so far used FormLayout.
The configuration settings are loaded using Plasma's ConfigLoader
and attached to the widget through a KConfigDialogManager.
Marking this commit as the one which implements QML support for
Aurorae themes:

For each theme the setting can be enabled individually with the
default being enabled by default. It is completely handled
inside the MenuButton QML component so each QML theme benefits
from the option automatically, too.

The Plastik decoration buttons are provided by a declarative
extension plugin as the canvas drawing API would be needed to
draw these buttons. This should be changed with Qt 5.
But it's also a nice example to show how a QML based decoration
can have an extension in C++.
When the decoration is reset a signal is emitted that the config
might have changed which the decoration can connect to for
reloading its configuration. For this an invokable method is
added to Aurorae allowing to read a config value which just
returns the QVariant.
Proper support for border sizes are added by providing the enum
in DecorationOptions, so that QML themes can use the enum values
to decide which border size to use.
The kcm is adjusted to also support these config mechanisms and
to properly load and save the border sizes for QML based themes.
On change of theme recreate all decorations and create a new
declarative engine and component which is basically a re-init
of the Factory.
There are too many differences between themes - especially when
switching between an old SVG based Aurorae and a new QML based
Aurorae theme.
Model is extended to support QML based Aurorae themes as well
the preview is able to handle it. For this a new qml component
is added which loads the decoration preview.
The generic QML components from Aurorae are split out into an
own declarative plugin. In addition two new helper classes are
added to this plugin:
* A ColorHelper to map a few function of KColorSheme and making
it possible to actually work with colors in QML. The need
emerged from trying to port Plastik to QML which makes strong
use of color shading.
* A DecorationOptions class which is a wrapper around KWin's
KDecorationOptions but in a more useable way for QML. The
various options are provided as properties and the value of
the properties changes automatically depending on whether the
decoration is active or inactive.
Aurorae itself is not yet adjusted to these changes, but it
should also be adjusted as some of the options are currently
exported in the factory and the factory is injected into the
Aurorae QML decoration.
Obsoletes the need to go through the Workspace object to get to
the Compositor.
TODO for future: make the Compositor being the parent object for
the EffectsHandlerImpl.

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.
The DBus signal which causes KWin to reinitialize the Compositor
is moved into the Compositor as everything can be handled from
there as well. This comes together with moving the restartKWin
functionality into the Compositor as it is only relevant there.
Restart will only happen if the wrong Qt graphicssystem is used
for the chosen compositing backend.
All the custom slot did was printing a debug statement and
calling finish. We do not need this debug statement. The times
of Compositors not part of Window Managers are over, so it is
extremely unlikely that we lose the ownership without KWin
going down anyway.
