Pinning my view to the upper left is easy using the

is pinned to the lower right. This seems to be due to the
flipped contentView.
Notes: 10.4 only; final document view must be an IB-built view/no custom
drawing needed or wanted.
I can't find any info on handling proper resizing. Any assistance/leads are
appreciated...
