title: Scroll NSScrollView contents to specific point, programmatically
body: <p>OK, this thing has been bugging me for quite some time.</p>
  
  <p>I've got an <code>NSScrollView</code> (X= 258, Y= 322, W=516, H=653)
  with a view in it (X= -283, Y= -215, W= 1800 H= 1800), and I'm desperately trying to make it scroll to the <strong>top-left corner</strong>.</p>
  
  <p>I've tried <code>[[_previewScrollView contentView] scrollToPoint:NSMakePoint(0,0)];</code> but it didn't help.</p>
  
  <p>Any ideas?</p>
