layoutPlaces関数

Where each place's marker and name go in one picture. A place on the far side of the Earth, or off the picture, is left out; one near the Earth's edge fades. The stick stands up from the ground as the picture sees it, leaning towards the top of the screen where the reader looks straight down on it, so it never shrinks to a dot; the ring at its foot is flattened as the ground is. A here place is taller and wider than a favourite. Names go at the top of the stick, here first and then in the order given, never over one another or over a box in taken; a name with no free place is left out. With sun, each shape says how far into the night its place is, so it can be drawn dimmer there.
