The nice illustrations from Sun helped understand this stuff, yes. IIRC Bjoern offered
to put them back into the final proposal based on my previous email.

Think of a vertical bar in bar chart. If you choose north-west then your point of
origin is the topleft corner of the bar. If you choose north-east then your point of
origin is the topright corner of the bar (and north is the middle point of the top edge).
So there isn't one point of origin, there are nine.

To be honest I'm not sure why we use north/west/south/east instead of top/left/bottom/right.
Both the Sun proposal and the KDChart code do use north/west/... for some reason :)
