Sorry, that one's my fault. That's a bad name from the very early days,
(before we had this nice community here). I'm sure the community here
wouldn't let me get away with a naming mistake like that today.

And if someone wants to propose better names for the transform_point and
transform_distance functions now, we could even deprecate the old names,
(of course, always accepting them so never breaking any code).

Hehe. Keep us posted as you need help. But it sounds like you're moving
along well.
