Faces - inferred - Sort "unknown" face clusters by cluster distance as secondary sort

[ChrisFab16]

In continuation of #601 , make a secondary sort criteria base on nearest distance in face cluster.

This will improve workflow to more quickly select many pictures of the same person.

Can you clarify what you mean by "nearest distance?" Do you mean sort within a cluster based on distance from the centroid of the cluster or the distance to the nearest point in the cluster?

Also, I think the probability (already the secondary sort) should be very similar to this. Are you envisioning something specific here?

Nothing too fancy - I've just noticed that when I have several groups of inferred faces with the same number of faces, the face groups tend to differ between persons - it would be a faster workflow if the "Unknown Person - ####"-groups that are likely of the same person would be presented in continuation of each other (as far of possible of course).

Does that make sense?
