I think if you want to change the state you can drag the linesegment, but you 
have to drag the points to change the duration.
An edit-model could be that points are y-constrained, and segments are 
x-constrained (well segments are allready anyway). 

And we need a different model/point heuristic because as soon as you dragged a 
segment like so:

____-___ to __________  

the controlpoints at the segment you just dragged will dissappear.(at least 
after a zoom)
Which in this case you don't want because you might want to turn that section 
on again.
This ought to work for all enumerated automation types (presets,mutes etc)
