iLabel is a dummy data member. The CPicture framework seems to assume that

anything to the stream we're given in ExternalizeL, then the stream store 
will abandon that stream and reuse its stream ID for the next picture. 
CStoreMap::BindL will subsequently panic because the map contains two identical 
stream IDs which refer to different pictures.
So we write something to the stream, to ensure that the store generates a 
unique ID for each picture.
