OK, I understand that autoresizing masks are converted, but one key issue is 
that I've read (in comments here) that when using constrants, I shouldn't use 
-setFrame: on a view, but instead modify the constraints. Using -setFrame: is a 
key part of what my old code does, and that works fine with struts and springs. 
If these are translated to constraints, it may be that things work OK until I 
call -setFrame:, at which point it blows up.

What I really want is that part of my view hierarchy to be free to use 
-setFrame:, but other parts use the autolayout constraints normally. The object 
is to avoid rewriting working code that has been functional for a decade, and 
so introducing a whole bunch of new bugs that will need a load of time to 
eliminate that I just don't have. There may be no general solution, but since 
the particular view is the content of a scroller, it might be possible to come 
up with a special case for this, because it seems constraints can't cross 
"scroller barriers", and that might therefore allow me to isolate the use of 
-setFrame: to this particular case.
