An abstract class implemented by palette clients to implement drag and drop
of new items into the palette window and to customize the default Transferable
instance of items being dragged from the palette window to editor area.
Client's can support multiple DataFlavors that may help to enable/disable the drop
when dragging an item over different editor area parts that allow only certain
item types to be dropped into them.
A class that listens to changes to the set of opened TopComponents and to the
set of activated Nodes to show/hide the palette window when a TopComponent that
supports the palette is activated/deactivated.
