Should get the internal display root window rather than the primary, and
generalize this to a helper method for setting rotation.

That being said, I'd prefer we find what is animating on a display update and
stop it from doing so. Since this seems to only happen in touchview I suspect,
directly or indirectly, that it's MaximizeModeWindowManager.

+    window->layer()->GetAnimator()->StopAnimating();
   }
 }
 
 void MaximizeModeController::SetDisplayRotation(
     DisplayManager* display_manager,
     gfx::Display::Rotation rotation) {
   base::AutoReset<bool> auto_in_set_screen_rotation(
       &in_set_screen_rotation_, true);
   display_manager->SetDisplayRotation(gfx::Display::InternalDisplayId(),
                                       rotation);
+  aura::Window* window(Shell::GetPrimaryRootWindow());
+  window->layer()->GetAnimator()->StopAnimating();
 }
