    //     however this can result in a much to narrow dialog instead and much unnecessary wrapping
    //   - Here we set a lower limit of GUI_MAX_LINE_LENGTH characters per line that long texts will always use
    //     This means texts can not shrink anymore (they can still grow, though) and it's also necessary
