You have to set the interpolation at the moment the image is being 
drawn, i.e. just before the NSImage draw/composite call. You can't do 
this using a regular NSImageView; it draws the image for you and has 
no ability to configure the interpolation.

You can either make a custom NSView and do the drawing in its -
drawRect: method; or you can create a scaled-up NSImage, draw the 
small NSImage into it using the appropriate interpolation, and then 
put the scaled-up NSImage into the NSImageView.
