With cropping on, the sampled latent is the crop's, which is exactly what a
refinement pass wants: the face has pixels there and the surrounding frame
never needed a second pass. But the node composited before returning, so
there was no way to get between the two.
paste_back: off now keeps images and latent in crop space, crop_bboxes comes
out alongside them, and the new BFS Head Swap Paste Back node composites at
the end with the same edge-aware feather and mask confinement.
