However, there is an argument, which I think I've heard Dean make in
the past, that 0° should point along the positive X axis (right) and
90° should point along the positive Y axis (down).  It's a little
confusing at first, but it does all fit together sensibly that way.

(I'm ok with the 0° pointing up and 90° pointing right, though.)
