org.apache.poi.ddf.EscherBSERecord
The BSE record is related closely to the EscherBlipRecord and stores extra information about the blip. A blip record is actually stored inside the BSE record even though the BSE record isn't actually a container record. @author Glen Stampoultzis @see EscherBlipRecord
