	// if you use auto layout, view-based transform go haywire, as they trigger layoutSubviews
	// consequence is that you have no idea where the view will end up on the screen once animation completes
	// see this discussion: http://stackoverflow.com/questions/12943107/how-do-i-adjust-the-anchor-point-of-a-calayer-when-auto-layout-is-being-used

	// thus (per solution 4 from link above), rewriting with CAKeyframeAnimation

	CAKeyframeAnimation *ka = [CAKeyframeAnimation animationWithKeyPath:@"transform"];
	ka.duration = .49;
