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).
