- * Generic UI Shape, potentially using a Graph via {@link GraphShape} or other means of representing content.
- * <p>
- * A shape includes the following build-in user-interactions
- * - drag shape w/ 1-pointer click, see {@link #setDraggable(boolean)}
- * - resize shape w/ 1-pointer click and drag in 1/4th bottom-left and bottom-right corner, see {@link #setResizable(boolean)}.
- * </p>
- * <p>
- * A shape is expected to have its 0/0 origin in its bottom-left corner, otherwise the drag-zoom sticky-edge will not work as expected.
- * </p>
- * <p>
- * GraphUI is GPU based and resolution independent.
- * </p>
- * <p>
- * GraphUI is intended to become an immediate- and retained-mode API.
