Detailed Description

Warning: This utility class is only functional when running with the default or software backends of the Qt Quick scenegraph. As an alternative, prefer using QSGRectangleNode via QQuickWindow::createRectangleNode(). However, this standalone class is still useful when used via subclassing and the application knows that no special scenegraph backends will be involved.
