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
