Enhanced Icon for Leading User through Drag and Drop Process

      Disclosed is an enhancement to the drag and drop icon that
would provide more information to the user during the drag and drop
process.  First, a brief overview of the drag and drop process in
it's current form, and then an explanation of how the icon can be
enhanced.

      Drag and drop allows the user to "pick up" objects on the
screen, "drag" them around the display, and "drop" them at a new
location, possibly in another application.  A drag and drop
transaction consists of the following actions:
  1.  A user presses and holds some assortment of modifiers and/or
       keys, usually mouse button 2, over a source object starting a
       drag transaction.  The application owning that object is the
       initiator of the drag.  The current pointer is replaced by a
       drag icon - a picture representing the item being dragged.
  2.  The user moves the pointer.  From now until a drop occurs, the
       drag icon replaces the mouse pointer.  The drag icon usually
       consists of three parts:
      * A part representing the type of source object, such as text.
      * A part used to show whether or not the object being dragged
         can be dropped at it's current location on the screen.
      * A part used to show what action should happen when the drop
         takes place.
     Parts of the drag icon may change shape or color as it is being
    dragged through potential drop sites, providing visual feedback
    about possible drop sites to the user.  These changes are
drag-over
    effects.  An object registered as a drop site may change visually
    as a drag icon passes over it.  These visual cues are drag-under
    effects.
  3.  The user drops the object, usually by releasing the assortment
of
       modifiers and/or keys.  Locations on the screen that can
accept
       drops are drop sites, and the application owning that drop
site
       is the destination or receiver.  The drag icon can be dropped
       anywhere on the  screen.  However, only certain objects have
       registered themselves as drop sites and are able to process
the
       drop.  The receiver application usually performs some action
on
       the information represented by the dragged icon.  The
initiator
       application may also perform some action based on the results
