/**
 * <p>This example mod does four things:
 * <p>
 * <p>1. Adds a red and yellow die to the left corner of the main menu (see RootMenuMixin)
 * <p>2. Changes the size of the characters shown in the main menu (see BackgroundInfoMixin)
 * <p>3. Adds a configuration which toggles whether the die is shown,
 * 		allows you to customize the eize of the characters in the main menu (see {@link ExampleModConfig})
 * <p>4. Reloads the main menu if the mod configuration is changed while it is open. (see {@link #onConfigChanged(ConfigSavedEvent)} and LegacyUIRootMixin)
