/**
 * Interface for classes that paint the background of an
 * RTextAreaBase.  The Strategy pattern is used for this
 * object because the background can be painted as a solid color, as
 * an image, and possibly other ways (gradients, animated images, etc.).
 * When a method to change the background of an RTextAreaBase
 * instance is called (such as setBackground,
 * setBackgroundImage or setBackgroundObject),
 * the correct strategy is then created and used to paint its background.
