/**
* This class is used to aggregate the MSODRAWING and OBJ record
* combinations. This is necessary due to the bizare way in which
* these records are serialized. What happens is that you get a
* combination of MSODRAWING -> OBJ -> MSODRAWING -> OBJ records
* but the escher records are serialized _across_ the MSODRAWING
* records.
*
* It gets even worse when you start looking at TXO records.
*
* So what we do with this class is aggregate lazily. That is
* we don't aggregate the MSODRAWING -> OBJ records unless we
* need to modify them.
