/**
 * Simple menu item -like layout implementation.
 * It only paints contents placed under {@link #ICON}, {@link #TEXT}, {@link #ACCELERATOR} and {@link #ARROW} constraints.
 * Do not use this layout for any {@link JMenuItem}, use {@link MenuItemLayout} instead as it contains some important features.
