/**
* Deserializes this <code>DragSource</code>. This method first performs default deserialization.
* Next, this object's <code>FlavorMap</code> is deserialized by using the next object in the
* stream. If the resulting <code>FlavorMap</code> is <code>null</code>, this object's <code>
* FlavorMap</code> is set to the default FlavorMap for this thread's <code>ClassLoader</code>.
* Next, this object's listeners are deserialized by reading a <code>null</code>-terminated
* sequence of 0 or more key/value pairs from the stream:
*
* <ul>
* <li>If a key object is a <code>String</code> equal to <code>dragSourceListenerK</code>, a
* <code>DragSourceListener</code> is deserialized using the corresponding value object and
* added to this <code>DragSource</code>.
* <li>If a key object is a <code>String</code> equal to <code>dragSourceMotionListenerK</code>,
* a <code>DragSourceMotionListener</code> is deserialized using the corresponding value
* object and added to this <code>DragSource</code>.
* <li>Otherwise, the key/value pair is skipped.
* </ul>
