Thanks Richard, I'll submit an additional note.
I agree that these are useful changes, in fact the reason I got into
the resizing issue is because of custom control I designed as a group
for my own app. It would just be so much better if changes like this
were documented in the dictionary.
I had noticed the selectGroupedControls property in the inspector
window but thanks for mentioning that too.

Thanks for adding that.
However, I didn't know until I read your email that
the resizeControl message is sent even when the resize happens by
script - that's the opposite of what the dictionary says. I don't
mind submitting another dictionary note for that but want to check
that it only applies to group resizing not resizing of any controls?
AFAIK that's the case. That was added to allow groups to be self-
contained when used to implement custom controls.
Imagine what a mess the DataGrid would be if you used in a stack in
which your resizeStack handler changes the DG's rect.
By allowing a group to be able to handle a resize no matter how that
resize happens, it can take care of its contents automatically.
Another enhancement added during the same period is that groups now
have their own selectGroupedControls property. It defaults to true
to allow the global property of the same name to govern whether you
can interact with the group's contents with the pointer too. But
when set to false the group's contents don't respond to the pointer
tool at all, allowing it to behave more like a native control.
These enhancements, coupled with behaviors to drive them from a
single script, open up all sorts of opportunities for crafting
reusable custom widgets.
