NSScrollView - keep document view's top left pinned when resizing?

I have a trivial(*) NSView subclass contained inside an NSScrollView.

I'd like to keep the top left pinned (like NSTextView and friends) 
when the scroll view resizes. By default, the bottom left of the 
visible rect is pinned.

How do I pin the top left while resizing? (I did read Scroll View 
programming guide. If the answer is in there, I missed it.)

[*] It just draws a big X across. That's it.

Thanks,
Jim
