+ * <h2>Nine-patch background painters</h2>
+ *
+ * Nine-patch background painters paint rectangles using a special nine-patch texture.
+ * The texture is divided into nine sections: four corners, four edges and a center part.
+ * The edges and the center are either tiled or stretched, depending on the mode of the painter,
+ * to fill the area between the corners. By default, the texture is tiled.
+ *
+ * <p>Nine-patch background painters are created using {@link #createNinePatch(Identifier)} or
+ * {@link #createNinePatch(Texture, Consumer)}. The latter lets you customise the look of
+ * the background more finely.
