 * Class to display graphics for a UML CallState in a diagram.
 * The UML 1.3 standard does not contain a description of CallState
 * in the Notation Guide chapters. The later UML versions correct this omission.
 * So, for UML 1.3 it looks the same as an ActionState.
 * The only difference with an ActionState is
 * the extra Well-Formedness rule for a CallState.
