I'd suggest that, rather than depending on only redrawing part of the foreground scene, you would do better to compose your view in an offscreen buffer and use that instead. Drawing to an offscreen buffer lends itself far better to incremental drawing and partial updates, and is therefore likely to be easier for what you are describing.
