They instead rely on cropping in the Image Stabilization module, at the output of the ISP, to modify the resizer input size and implement digital zoom. Support those ISP versions by addind a dual crop feature flag, and mapping the resizer input crop rectangle to either the resizer dual crop module or the image stabilization module.
