Clipping a group by script

[Bob Sneidar]

Hmmm… I wrote a handler to determine the rect of all the visible objects on a card so I can set the stack rect to that plus margins. It involved getting the left, top, right and bottom as seperate values, of every visible object, then determining the min and max of each set of values as needed. You should be able to something similar.
