// sure that the WinAPI notion of the window position is maintained/
// restored, possibly undoing or overriding Cocoa's adjustment.
//
// So, we queue a REASSERT_WINDOW_POSITION event to the back end before
// Cocoa has a chance to adjust the frame, thus preceding any resulting
// WINDOW_FRAME_CHANGED event that may get queued. The back end will
// reassert its notion of the position. That call won't get processed
// until after this method returns, so it will override whatever this
// method does to the window position. It will also discard any pending
// WINDOW_FRAME_CHANGED events.
//
// Unfortunately, the only way I've found to know when Cocoa is _about to_
// adjust the window's position due to a display change is to hook into
// this private method. This private method has remained stable from 10.6
// through 10.11. If it does change, the most likely thing is that it
// will be removed and no longer called and this fix will simply stop
// working. The only real danger would be if Apple changed the return type
// to a struct or floating-point type, which would change the calling
// convention.
