title: SKCropNode - Cropped node responding to touch
body: <p>I am trying to make a sort of a scroll view using SKCropNode. The size of the scroll view is set to the mask node and the child nodes are then cropped when they move outside the mask's region. I have put various subclassed SKSpriteNodes, each with their own touch events, on this scroll view. However, they still respond to the touch events even while being cropped out!</p>
  
  <p>Can anyone suggest a way to resolve this?</p>
