Is there a value exposed by OSD that I could tween to control the animation? Or perhaps I would I need to write a custom Spring implementation? If you know of any examples where custom animations are used that would really help me. For context, the reason I'm doing this is because my image is very large, so when making large jumps the user looses the context of the overall image. By zooming out and back in they will (hopefully) keep their mental picture of the, um picture.
