An Icon wrapper class which implements UIResource.  UI
classes which set icon properties should use this class
to wrap any icons specified as defaults.
This class delegates all method invocations to the
Icon "delegate" object specified at construction.

Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing.  As of 1.4, support for long term storage
of all JavaBeans
has been added to the java.beans package. Please see XMLEncoder.
