   identifies Boopsi gadgets with a GadgetCV object.

   likely to change due to user activity.
   Since the underlying BoopsiGadget is disposed and recreated each time the windowsize
   changes the IntuiObject creation taglist is applied for recreation, and all tags that
   are not explicitly set will adopt default values.
