So the original designer of the LDraw program just decided to use this
orientation of the right handed system. if so then it starts making more
sense to me, I just need to redefine 'front, left, right etc' to fit in
this orientation for editing.
I'll make it an option (LDraw orientation 'standard' orientation).
Because personally I find a upward negative Y very confusing, but I
suspect that the LDraw die hards are custom to it.
But in essence no changes are made to the coordinates (only the camera
position), so it doesn't really matter how you label the sides :)
