The default behavior of groups (automatically resizing to fit their 
interior controls) is not limited to adjusting the rects of those 
controls by script.  If you move them with the pointer tool you'll see 
the same expansion of the group to accommodate them.

Prior to the clipsToRect property you can get the same clipping by 
locking the location of the group.

While clipping is rarely needed, this is a great convenience for those 
times when it is.

Another property worth noting is the boundingRect, which limits the 
scrollable are in a group to a specified rect.  This can be esp. useful 
for apps that include a drawing/layout UI, letting you limit the 
scrolling group to mimic a fixed page size, for example.
