   13         * been prepared in a way which permits the Owner and the WaterClass to
   14         * be set to their intended values.
   15         *
   16         * A canal tile owned by OWNER_NONE has been made sure to have never
   17         * been demolished during preparation, as that is needed to retrieve
   18         * its respective owner, whenever it finds a river tile.
   19         *
   20         * If a river tile is found, it can mean either the previous function
   21         * demolished own canal and a river was restored, as per the Canal on
   22         * River patch's behaviour, or it is indeed a river tile which, albeit
   23         * being demolished, it is kept, as per the Permanent Rivers patch
   24         * behaviour.
   25         * This is not enough to decide on the owner, but the previous function
   26         * has assigned a bit value to indicate if there was originally a canal.
   27         * If it was set, it means the canal was ours, and not from another
   28         * owner. If the bit was not set, then it was indeed a river.
   29         *
   30         * If a bare land tile is found at this stage, then it is known that no
   31         * river was ever originally present, but it could have been a canal or
   32         * a sea tile. To figure it out, it resorts to checking the original
   33         * WaterClass of the tile even before the clearance test had happen.
   34         * If it was sea, then it sets the owner to OWNER_WATER. If it was a
   35         * canal then it knows that only own canals could have been demolished
   36         * during the clearance check previously, and also that canals
   37         * owned by OWNER_NONE are not demolished.
