Surely, though, the long exposure scan option already requires both
passes to be buffered in memory?  If registration were activated with
this option, there wouldn't be any additional memory overhead.  I know
there are some occasions colour fringing/transition issues with the long
exposure pass facility - maybe this sort of registration would improve
this as well?
