title: Flip coordinate system of an NSWindow objective-c / cocoa
body: <p>How can I flip the coordinate system of an NSWindow? I know it has a Content View, but how can I flip the coordinate system of that specific View which is of type NSView?</p>
  
  <p>In a sub-view of my NSWindow's Content View I flip the coordinate system by subclassing NSView, placing that in my window, and in that subclassed NSView I implement method isFlipped to return YES.  No idea how I could have NSWindow make it's content view out of "MyFlippedSubclassedNSView"</p>
