title: NSImageView image aspect fill?
body: <p>So I am used to <code>UIImageView</code>, and being able to set different ways of how its image is displayed in it. Like for example <code>AspectFill</code> mode etc...</p>
  
  <p>I would like to accomplish the same thing using <code>NSImageView</code> on a mac app. Does <code>NSImageView</code> work similarly to <code>UIImageView</code> in that regard or how would I go about showing an image in an <code>NSImageView</code> and picking different ways of displaying that image?</p>
