Ah, I stand corrected! I don't remember why I thought that, though I do
remember the discussion about how this is the opposite of "normal" - except I
was introduced to 3D coordinates using POV, so the left hand system is now
normal to me. But anyway, as Warp mentioned, it can be flipped as can the
objects if needed.

<grin> POV is so versatile that it doesn't matter; I just mentioned the
default (indeed) because, like you, the left-hand system has become so
natural to me that I was taken by surprise. No harm done.
