[O] face for upcoming deadlines in agenda

[Alex Branham]

Is there a face that controls agenda items with an upcoming deadline are
displayed? It seems to just use "default" for me. I'm talking about
items with a deadline within 'org-deadline-warning-days' number of days
from now.

If not, is there any way of getting someone to implement that? I'd do it
myself, but the way Emacs deals with faces is a bit of a mystery to me.

Thanks,
Alex
