  46     For BIFF import, it is needed to load all drawing objects before converting
  47     them to UNO shapes. There might be some dummy drawing objects (e.g. the
  48     dropdown buttons of autofilters) which have to be skipped. The information,
  49     that a drawing object is a dummy object, may be located after the drawing
  50     objects themselves.
  51
  52     The BIFF8 format stores drawing objects in the DFF stream (stored
  53     fragmented in MSODRAWING records), and in the OBJ records. The DFF stream
  54     fragments are collected in a single stream, and the complete stream will be
  55     processed afterwards.
