misleading comment

[matthiasclasen]

add_layout_stays has a comment that says: /* Add two required stay constraints for the top left corner */
but looking at the code:

1. it also creates stay constraints for width and height
2. it creates weak constraints, not required ones

Who is right, the comment or the code ?

looking at the git history, the comment seems to be a leftover from the initial setup, and hasn't been kept up-to-date with later changes
