PropertySource which permits setting the values of JAI properties in addition to obtaining their names and values. As the values of properties managed by classes which implement this interface may change, this is also a sub-interface of PropertyChangeEmitter. This permits other objects to register as listeners of particular JAI properties. The case of the names of properties added via this interface should be retained although the case will be ignored in queries via getProperty() and will be forced to lower case in emitted PropertySourceChangeEvent.
