Yep, those are good triggers too, still allowing the group to manage its 
own contents.

Orientation changes would still need resizeStack or orientationChanged 
to be handled, though, which is one convenience with using resizeStack 
for both.

My test devices here each have different screen dimensions, so I rarely 
save my stack in the exact dimensions of the next device I'll run it on.

So I ran a test before I made that last post, in which I set my stack to 
the screen dimensions of the phone nearest me, then ran it on that 
phone:  I got the resizeStack message anyway.

I thought I'd read a post here some time ago about this from one of the 
regulars who's shipped a lot of mobile apps, how on mobile the 
resizeStack message is sent when a stack is first opened in addition to 
when orientation changes.

That's what got me started down this path, and it's been working so 
reliably on Android that I hadn't considered perhaps I'm relying on a bug.

Either way, it would be great if the engine sent the resizeStack message 
under the same circumstances on both iOS and Android.

As it appears on Android right now, even if it's an exception to 
whatever rules are supposed to apply, it's a darn handy one, which was 
what led me to believe it was a design decision.
