How to implement zoom/scale in a Cocoa AppKit-application

How do you implement zoom/scale in a Cocoa AppKit-application (i.e. not maximizing the window but scaling the window and all its subviews)? I think it's called zoomScale in iOS. Can it be done using Core Animations or Quartz 2D (e.g. CGContextScaleCTM) or am I forced to implement it manually in all my NSViews, NSCells, etc?
