/**
 * The {@code DragSourceDragEvent} is
 * delivered from the {@code DragSourceContextPeer},
 * via the {@code DragSourceContext}, to the {@code DragSourceListener}
 * registered with that {@code DragSourceContext} and with its associated
 * {@code DragSource}.
 * <p>
 * The {@code DragSourceDragEvent} reports the <i>target drop action</i>
 * and the <i>user drop action</i> that reflect the current state of
 * the drag operation.
 * <p>
 * <i>Target drop action</i> is one of {@code DnDConstants} that represents
 * the drop action selected by the current drop target if this drop action is
 * supported by the drag source or {@code DnDConstants.ACTION_NONE} if this
 * drop action is not supported by the drag source.
 * <p>
 * <i>User drop action</i> depends on the drop actions supported by the drag
 * source and the drop action selected by the user. The user can select a drop
 * action by pressing modifier keys during the drag operation:
 * <pre>
 *   Ctrl + Shift -&gt; ACTION_LINK
 *   Ctrl         -&gt; ACTION_COPY
 *   Shift        -&gt; ACTION_MOVE
 * </pre>
 * If the user selects a drop action, the <i>user drop action</i> is one of
 * {@code DnDConstants} that represents the selected drop action if this
 * drop action is supported by the drag source or
 * {@code DnDConstants.ACTION_NONE} if this drop action is not supported
 * by the drag source.
 * <p>
 * If the user doesn't select a drop action, the set of
 * {@code DnDConstants} that represents the set of drop actions supported
 * by the drag source is searched for {@code DnDConstants.ACTION_MOVE},
 * then for {@code DnDConstants.ACTION_COPY}, then for
 * {@code DnDConstants.ACTION_LINK} and the <i>user drop action</i> is the
 * first constant found. If no constant is found the <i>user drop action</i>
 * is {@code DnDConstants.ACTION_NONE}.
