Ah, ok. I tried this on 1.3.4 before my recent upgrade and it didn't 
seem to do anything. I'll play around some more with the new version.

This was what I was playing with. Seems to do what I wanted, although 
I've not got time to finish atm.

Ok, no problem as it's not a serious requirement,just lazyness! ;)

Actually, that would be *cool*. But then I'd want delays in blitting as 
part of the list and, and... ;P
