* \brief Helper class for painting video on a QtQuick2 VideoItem
*
* This is a helper class that represents a video surface on a QQuickView.
* To use it, create a VideoItem from QML and connect it with this surface.
*
* Example:
* \code
* // in your C++ code
* QQuickView *view = new QQuickView;
* ...
* QGst::Quick::VideoSurface *surface = new QGst::Quick::VideoSurface;
* view->rootContext()->setContextProperty(QLatin1String("videoSurface"), surface);
* ...
* // and in your qml file:
* import QtGStreamer 1.0
* ...
* VideoItem {
* id: video
* width: 320
* height: 240
* surface: videoSurface
* }
* \endcode
*
* \sa VideoItem
