title: Disable NSView mousedown
body: <p>i have an NSScrollView with an NSView set as its document view. I am trying to get the mousedown event in the NSScrollView but the NSView keeps intercepting it. Is there a way of stopping this from happening?</p>
  
  <p>Also is there a way of stopping it in one area of the view much like an NSTrackingArea does for mouseentered.</p>
  
  <p>Thanks in advance,</p>
  
  <p>Ben</p>
