/**
 * Contains all of the classes for creating user interfaces and for painting
 * graphics and images. A user interface object such as a button or a scrollbar
 * is called, in AWT terminology, a component. The Component class is the root
 * of all AWT components. See Component for a detailed description of properties
 * that all AWT components share.
 * <p>
 * Some components fire events when a user interacts with the components. The
 * AWTEvent class and its subclasses are used to represent the events that AWT
 * components can fire. See AWTEvent for a description of the AWT event model.
 * <p>
 * A container is a component that can contain components and other containers.
 * A container can also have a layout manager that controls the visual placement
 * of components in the container. The AWT package contains several layout
 * manager classes and an interface for building your own layout manager. See
 * Container and LayoutManager for more information.
 * <p>
 * Each {@code Component} object is limited in its maximum size and its location
 * because the values are stored as an integer. Also, a platform may further
 * restrict maximum size and location coordinates. The exact maximum values are
 * dependent on the platform. There is no way to change these maximum values,
 * either in Java code or in native code. These limitations also impose
 * restrictions on component layout. If the bounds of a Component object exceed
 * a platform limit, there is no way to properly arrange them within a Container
 * object. The object's bounds are defined by any object's coordinate in
 * combination with its size on a respective axis.
