This interface is used for asynchronously-loaded contents. For example, the {@link SvgBatikResizableIcon} uses the {@link ExecutorService} to load theSVG image in the background. When the image is loaded, the component that contains this image ( {@link JCommandButton} for example) is notified torepaint itself. @author Kirill Grouchnikov.
