Window Thumbnail support for QML A new QML item "ThumbnailItem" is registered to the TabBox. The C++ implementation finds the EffectWindow of the TabBox and adds itself to the EffectWindow. While rendering the EffectWindow the information for all registered ThumbnailItems are extracted and the thumbnail is rendered on top of the EffectWindow. This has obvious limitations like you cannot put other QML items on top of the thumbnail. Nevertheless it works well enough to be a possible replacement for e.g. BoxSwitch effect. When compositing is disabled an icon is rendered instead of the Thumbnail. One TabBox Layout inspired by BoxSwitch Effect is added. For the KCM small pre-rendered items are used. REVIEW: 103039

Q_OBJECT
Q_PROPERTY(qulonglong wId READ wId WRITE setWId NOTIFY wIdChanged SCRIPTABLE true)
Adding a clip property to the ThumbnailItem By default clip is enabled. This means that if the thumbnail would overlap the "parent" window, it does not get rendered at all. If set to false it will always be rendered. This is required for window strip where the complete screen width is used, so overlap does not matter.

Q_PROPERTY(bool clip READ isClip WRITE setClip NOTIFY clipChanged SCRIPTABLE true)
Support specifying the parent window on which the thumbnail is shown ThumbnailItem tries to find the window where it is embedded in through a context propery containing the window id of the declarative view. This works fine for e.g. TabBox but not for Plasma.Dialog as that opens a new window. REVIEW: 104394
