They reflect the areas controlled by hinting, autohinting if you
haven't done anything by hand. Green is horizontal, blue
vertical. They illustrate whether you have any unwelcome
overlaps that will cause problems with rendering. You can get
rid of them by clearing the hints, but you probably shouldn't
unless you're sure you're going to do your own hinting by hand
(which in general is more trouble than it's worth, nowadays).
