So I think this is the problem. The Right Fix I think is to:

1. Declare these methods in ui/views/cocoa/views_nswindow_delegate.h
2. Assert that [window delegate] is a ViewsNSWindowDelegate (if this wasn't true
this test wouldn't pass on 10.6)
3. Cast the pointer to ViewsNSWindowDelegate, and call the method there directly

1. I declared the relevant methods in ui/views/cocoa/views_nswindow_delegate.h.
2. This test doesn't run on OSX 10.6, so I left out the assert.
3. I used base::mac::ObjCCast.

   // Now perform a successful fullscreen operation.
