When I think of it some more, maybe it is not so strange after all. 
In the dragon2_data struct, we have the following two declarations:

  int moyo_size;                      /* size of surrounding influence moyo, */
  float moyo_territorial_value;       /* ...and its territorial value        */

Maybe we can get what we want by just saying that the moyo is defined
as moyo_size - moyo_territorial_value.  The inside and the outside is
also not always that well defined, especially not for a group in the
center.  What is strange, though is that moyo_size is an int.
Shouldn't that be a float as well?
