Shouldn't this be propagated to the frame's crop fields, and back from
the crop fields to the packet side-data?
We no longer use frames and packets to communicate global side data, and
we can't use frame cropping values as global metadata for the
container's header because there's codec level cropping too (like h264
to remove padding coded at certain dimensions) in them.
