public abstract class AbstractDrawable
extends java.lang.Object
implements Drawable

this class represents a simple implementation of the 'drawable' interface. it is handy in those cases in which only a few of the methods required by the 'drawable' interface are needed. the 'draw' method is intentionally left unimplemented since it is the only method with a 'real' important functionality.
