Summary:
Changing the alternateImage on an NSButton does not cause the button to redraw properly if one of its superviews is layer-backed.

Steps to Reproduce:
1. Add a button to a layer-backed view hierarchy.
2. Ensure it is displaying its alternate image (i.e. is in NSOnState).
3. Call -setAlternateImage: on the button with a different image.

Expected Results:
The button should change its alternate image and redraw.

Actual Results:
The button does not change appearance.

Version:
Xcode 5.0.1 (5A2034a) / OS X 10.9 (13A603)

Notes:
Sample project attached. To demonstrate the issue, run, then press the second button (labeled "Change That Button's Alternate Image!").

Calling -setNeedsDisplay: on the button with a YES argument does not fix this problem.
