Square profile picture option?

it would just be a nice option for customization.
that's all, i think people would like it.
not like it would do any bad, since it's optional and all.

side note: i noticed this suggestion has been made before, and usually gets loads of down votes.
i don't get why that would happen, since it's just a small option for people who want it.
maybe they were just suggesting it in the wrong places.
