That's the convention for mathematical graphing, sure. In programming
environments, it's common to define axes so that the down and right
directions are positive. I have no idea which of these alternatives
would be more transparent for the most users.
Maybe we should ask Ed to use complex numbers (x +iy) to represent the
focus points....
Sorry, I'm just being silly again. This thread is getting long.
