1.Select the smaller downscaling ratio for both sides as rotator needs do the same downscaling for both direction. 2. Use rotator to do the minimum downscaling first to get the best quality. Use decimation when rotator downscaling is not enough. 3. Assign z_order when doing resource configuration. 4. For non src split case, if two pipes are on one mixer, need make sure right pipe has the different z_order. Change-Id: I1b829545053c2b719da8b6b42c1e5341a5040bcc
