I have a NSScrollView with a NSImageVIew within.
I'm using magnification enabled on NSScrollView.
I'm seeing a funny downward drift of the NSImageView when scaling using a 'pinch' gesture on my MBP track pad.
If you pinch and un-pinch continuously ... zooming in and out, the image drifts downwards within the NSScrollView. Can't explain it or locate bug.

What am I doing wrong ?
