/** Base class for a container for all objects on a drawing page (in a
    spreadsheet or in an embedded chart object).

    For BIFF import, it is needed to load all drawing objects before converting
    them to UNO shapes. There might be some dummy drawing objects (e.g. the
    dropdown buttons of autofilters) which have to be skipped. The information,
    that a drawing object is a dummy object, may be located after the drawing
    objects themselves.

    The BIFF8 format stores drawing objects in the DFF stream (stored
    fragmented in MSODRAWING records), and in the OBJ records. The DFF stream
    fragments are collected in a single stream, and the complete stream will be
    processed afterwards.
