/* The code is copied from Ragundo's repo referenced below.
The changes are:
- The addition of a .h file reference.
- The simplification of the code using ofsub to remove the use of (and
.h reference to) that function (analysis of the code showed the
simplified code is the result, as the ofsub expressions will never be
true given the range of the values it can be passed in these functions).
- The change of the main function to take a separate y coordinate for
use in the tropicality determination to allow proper determination of
the tropicality of mid level tiles ("region tiles") referencing a
neighboring world tile's biome.
