-extensions in cells. They must be >= 1 and <= 256. The numbers after
-"DIST_ORTHOGONAL" and "DIST_DIAGONAL" define the diagonal movement penalty as
-the second value divided by the first. The above values define a penalty ratio
-of 7/5 or 1.4, i.e. it takes 40% longer in turns to move diagonally than
-orthogonally. Set both to the same value to eliminate the diagonal movement
-penalty. A negative penalty to realize weird geometry is possible by setting
-"DIST_DIAGONAL" to a lower value than "DIST_ORTHOGONAL". Both values, however,
-must be >= 1 and <= 255.
