Adding a new property on whether we want animations based on whether we
are on raster or with Compositing. The property is constant as the deco
gets recreated on compositing change state anyway.

The Borders element provides the four properties:
* left
* right
* top
* bottom
And is used directly in Decoration for all the different kind of settings
following this pattern:
* normal borders
* maximized borders
* padding
* extended borders
These properties replace the existing used borderLeft & co. This makes
the code in the C++ side easier as the various border elements can now be
read with a shared implementation.
The Borders provide some convenient methods to set the sizes of the
borders. E.g. it's possible to just set the side borders to a specific
value. This should simplify the implementation of the no-side-borders
feature in new decoration.
The aurorae qml and plastik are adjusted to use the new way. Existing
3rd party decorations would break, but there's a good reason why there's
no documentation for QML based decorations ;-)

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.

A decoration can provide the AbilityAnnounceAlphaChannel in addition to
AbilityUsesAlphaChannel. If this ability is provided the decoration can
enable/disable the use of the alpha channel through setAlphaEnabled().
The base idea behind this mechanism is to be able to tell the compositor
that currently alpha is not needed. An example is the maximized state in
which the decoration is fully opaque so that there is no need to use the
translucency code path which would render all windows behind the deco.
In addition also the blur effect honors this setting so that behind a
known opaque decoration no blurring is performed.
Oxygen is adjusted to disable translucency in maximized state and Aurorae
is adjusted to allow themes to enable/disable translucency. For Plastik
translucency and with that also blurring is disabled.

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.
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.
The result of maximizing a window might be the decoration
going away. Because of that we need to delay the handling of
maximize and title bar double click by one cycle as had been
done for other close operations in 0fea5325

Unfortunately QtQuick 1 does not provide a way to receive Wheel
events. But the window decoration needs to pass wheel events on
the titlebar to KWin core.
In order to process also Wheel Events in Aurorae an event
filter is installed on the widget and in case the mouse positon
is on the title bar the titlebarMouseWheelOperation is invoked.

REVIEW: 105801
This is an issue we already had in the past with Aurorae. When
closing a window the graphics scene crashes because the deco
gets destroyed before the code in the graphics scene finished
the execution.
With the port to QML this seemed to be fixed unless as it turns
out it throws an XIO error on closing:
fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
This can be triggered using glxgears. Closing glxgears would
reliable crash Aurorae. To circumvent this issue we have to
delay the close by one event cycle using QMetaObject's
invokeMethod with a Qt::QueuedConnection.
This has also to be done in the useractions menu as the menu
is still open when the window closes causing the same problem
inside Aurorae.

The general idea is: single click opens menu, double click closes
the window. The problem is that the when the menu is opened after
the single click, the menu will eat the second click. So double
click will not work.
This commit brings back the workaround from Aurorae2. The clicked
event is not used at all, but we start a timer on the press event
with the doubleClickInterval. If no double click appears during the
interval we open the menu, if there is a double click we close the
window.
The downside of this approach is that there is a slight delay between
clicking the menu button and the menu appearing. For that the right
click behavior is unchanged. That is right clicking opens the menu
instantly and double click to close it, is broken.
Buttons are exported as a global "options" in the factory.
Additionally the theme's buttons are also exported. The thme decided
based on the custom button positions property which one to use.
In the kcm the button options are also exported.
Each decoration gets a graphicsview and scene instead and a declarative
item is created for each decoration.
There's probably still room for improvments. E.g. never render the
scene onto the widget but directly into the textures?
What's working:
* background for active and inactive decorations inclusive transitions
* all buttons get loaded
* transition between button states
* all borders, paddings etc is working
* mouse interaction with buttons and title area
What's not yet working:
* special maximize mode
* mouse wheel on title area
* window tabs
* changing themes
* crash resistence (currently a not compiling QML file crashes KWin badly)
* window/blur mask (tricky - we need the alpha mask of the background SVG)
What's going to be dropped:
* special opaque mode
* decoration position at left/right/bottom instead of top
Why? Because nobody uses these features
It should support everything the old engine supported. Only known regression is the lack of tooltips.
Now finally Aurorae is ready to get window tab support \o/

So finally we have the shadow back when resuming. Of course it would be nice if kwin would just inform the decos and they don't have to watch for themselves ;-)

This theme engine uses SVG files to theme the decoration like the themes for Plasma desktop shell.
