Basically, that dictionary entry is wrong.
If you *change* the size of a group by script, then that group *does*
receive a resizeControl message.
Note that it does *not* receive a mesage just because the rect changes -
only if the size changes.
So if you do something like
repeat 10 times
add 1 to X
set the rect of grp "A" to X,Y, X+100, Y+100
end repeat
then grp "A" will get either 0 or 1 message (from the first time through
the loop).
If you do
repeat 10 times
add 1 to X
set the rect of grp "A" to 100,Y, X+100, Y+100
end repeat
it will receive either 9 or 10 messages.
So, essentially I think, your wish is already true :-)

(Yes, tested pretty thoroughly in 10.0DP6 but I believe also true in
earlier versions; I had to re-test this two days ago while playing with
the recent benchmarking of groups vs cards).
