So much for avoiding the minefield! I really did not mean to steer this
conversation that way. Anyhow I think we are talking about coordinates
and not points. What I got out of the past discussions on points was
that a "Point" is completely different than the coordinates used to
describe it, and that there is this whole slew of semantic issues verses
performance tradeoffs regarding things like the fact that vectors are
not points, you can not add points, etc.
