Like the pooh reference!
Although I am not sure I follow exactly what you are suggests - AND - I
need to do this via math rather than visible (or invisible) objects in LC.
for rects r1,r2, I have l1,t1,r1,b2 and l2,t2,r2,b2 for their
coordinates. The rect min(l1,l2),min(t1,t2),max(r1,r2),max(b1,b2) is a
rectangle that exactly bounds both rects - this would be the rect of the
group (if you created them as objects and grouped them (less
I don't follow the part about 'centered on a larger rect where the
margin is d/2?
