This must be called. We can only initialize this object completely if we know all connections are valid. Some other object drives this and so the connection's initialize will be called after. The job of this connection is to set up the sequence. It will default to the bounding rect. The area of interest can be set to some other rectagle (use setAreaOfInterest).
