These two phases should now be in.  Resizing segments non-
destructively appears to be working (the segment canvas doesn't
update the previews and things properly, but as far as I can
tell the underlying behaviour is okay) and you can now do things
like telling the segment to end in the middle of a note,
whereupon the sequence manager should truncate it and cut out or
start the next loop correctly.

The notation editor and matrix are not yet aware of end markers:
that's phase D.

There are plenty of bugs, I'm sure -- please let me know of any
you find (if you want to fix them, go ahead but it's probably
best to check with me that you have the right fix as there may
be cases where we should be doing something completely new
instead of patching up old code).  One that I'm aware of is that
undo doesn't seem to work for Split Segment (although the split
itself appears to work okay).
