I dunno, sq_distance seems obvious enough to me.  That's what it's
called already (in sq_map_distance)  I have no idea what mod_sq or
norm_sq means (well, not without resorting to math training anyway).

As for the xxx_to_xxx() "conversion" naming method, I have no real
opinion - it just seemed natural at the time.

Maybe get_vector_length_sq()?  vector_get_visual_distance_sq()?
