43 * @class RootNode
44 *
45 * A QSGClipNode derived class used as a container for holding pointers to nodes and for clipping.
46 * Upon construction RootNode generates all textures that are used by PointNode.
47 *
48 * KStars Lite has the following hierarchy:
49 * 1. RootNode - the parent of all nodes that also acts as a clipping node
50 * 2. SkyItem derived nodes that acts like SkyComponent in regular KStars
51 * 3. SkyNode derived nodes that represent SkyObjects (similar to SkyComponent::draw())
52 * 4. Simple nodes like EllipseNode or PointNode that draw basic geometry and stars
53 *
54 * @short A container for nodes that holds collection of textures for stars and provides clipping
55 * @author Artem Fedoskin
56 * @version 1.0
