+/** Dragging/Copying/Cutting Scenario:
+  * - User select some notes and cut them;
+  * - NoteDrag::toMultipleDrag() is called with a tree of the selected notes (see Basket::toSelectionTree()):
+  *   - This method create a new KMultipleDrag object, create a stream,
+  *   - And then browse all notes and call the virtual Note::serialize() with the stream as parameter for them to serialize theire content in the "native format".
+  *   - This give the MIME type "application/x-basket-note" that will be used by the application to paste the notes exactly as they were.
+  *   - Then the method try to set alterante formats for the dragged objects:
+  *   - It call successively toText() for each notes and stack up the result so theire is ONE big text flavour to add to the KMultipleDrag object
+  *   - It do the same with toHtml(), toImage() and toLink() to have those flavours as well, if possible...
+  *   - If there is only ONE copied note, addAlternateDragObjects() is called on it, so that Unknown objects can be dragged "as is".
+  *   - It's OK for the flavours. The method finally set the drag feedback pixmap by asking every selected notes to draw the content to a small pixmap.
+  *   - The pixmaps are joined to one big pixmap (but it should not exceed a defined size) and a border is drawn on this image.
