For now it can only do cropping or add a border with a width/height that is a
multiple of the subsampling.

The way it was done before is actually not correct anyway, it causes a chroma
shift. If we want to implement this correctly we have to move the chroma with a
half pixel when we crop the luma. Not sure it is worth it for now.
