* 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 setBackgoundObject),
* the correct strategy is then created and used to paint its background.
