Topology function to find the vector which has the minimum "real" distance between the map positions (x0, y0) and (x1, y1). If there is more than one vector with equal distance, no guarantee is made about which is found.
Real distance is defined as the larger of the distances in the x and y direction; since units can travel diagonally this is the "real" distance a unit has to travel to get from point to point.
(See also: real_map_distance(), map_distance(), and sq_map_distance().)
With the standard topology the ranges of the return value are: -map.xsize / 2 <= dx <= map.xsize / 2 -map.ysize < dy < map.ysize

Returns the relative southness of this map position. This is a value in the range of [0.0, 1.0]. This function handles all topology-specific information so that all other generator code can work in a topology-agnostic way.
Relative southness is 0.0 at the northernmost point and 1.0 at the southernmost point on the map. These may or may not be polar regions (depending on various generator settings). On a map representing only a northern hemisphere, southness directly corresponds to colatitude, going from 0.0 at the pole to 1.0 at the equator. On a map representing only a southern hemisphere, it directly corrsponds to (negative) latitude, going from 0.0 at the equator to 1.0 at the pole.

The basic cost to move punit from tile t1 to tile t2. That is, tile_move_cost(), with pre-calculated tile pointers; the tiles are assumed to be adjacent, and the (x, y) values are used only to get the river bonus correct.
May also be used with punit == nullptr, in which case punit tests are not done (for unit-independent results).
