[ Being an average programmer, and not knowing precisely what the *current*

Well, `normal' or `normalized' suggests `standard, unique' while
`proper' suggests `useful, real' to me.
Also `normal' is `one choice among many' (the vector example) while
usually `proper' is `one of the most, excluding a few improper ones'.

So, speaking of map coordinates, `normal' suggests me a unique, standard
representation. `proper' means real, "not virtual". A given tile may
have many different `proper' coordinates, but only one `normal' form.

I'd just say that `proper' is a property that depends on the tile itself,
`normal' it's just one coordinates representation.
