[M4IF Technotes] max of 4 objects in SP/ASP

[Gaurav Aggarwal]

Thanks a lot for replying. I should have realized on my own :(
Anyhow, what to do with the 4 objects? We would need some
kind of compositor, right? But this doesn't seem to part of the
spec. So are we open to the method used to display 1 or more 
out of the 4 objects that may come in the stream.
