* ProxyAction is a proxy for an Action instance. All Action methods are proxied except for <code>actionPerformed()</code>.
* That means all properties of the proxied Action are preserved but the proxied Action is not performed.
*
* <p>ProxyAction is useful to keep the visual properties of an Action instance in a component (JButton for instance)
* but perform a different action.
*
* <p>This class is abstract, leaving <code>actionPerformed()</code> unimplemented. {@link MuteProxyAction} provides an
* implementation where <code>actionPerformed()</code> does nothing.
