            Additional river information:
            The flow element affects the width of the river and seems to follow the
            formula width = (flow / 40000 * 46) + 1, with a minimum width of 4 and
            a maximum width of 47. DF uses specific names for rivers with certain flows:
            - Stream:      less than 5000
            - Minor River  5000 - 9999
            - River        10000 - 19999
            - Major River: greather than 20000
            Brooks tend to have a flow of 0, but DF has divided the controlling information
            between this structure, the region map entry (below), and the feature map.
            Thus, the region map flag 'is_brook' controls whether a water course actually
            is a (potentially broad) brook or an open water course. Likewise, the 'has_river'
            flag is needed for DF to properly understand a water course should be present.
            The exit tile holds the information on which mid level tile the river should
            exit the region. Presumably the path controls which edge to apply this to.
            Note that the river up/down/left/right flags of the region map entry should
            align with the sides rivers enter/exit.
            The feature map has to have a river entry for the corresponding world tile
            for a river to be implemented properly. All this is done by DF, but needs
            to be known if hacking.
            The world region details (below) data on rivers are generated as the regions
            are generated.
            The elevation element affects the level of the river. If the river elevation
            is lower than the surrounding area DF tends to generate a valley around the
            river to allow it to reach the correct elevation.

            After this, each corner and edge segment is assigned the biome
            of one of the adjoining 4 or 2 embark tiles, based on the values
            in these arrays. It may be necessary to access adjacent details
            objects to collect the full outline:

            c11 x11 | c21
            y11 *** | y21
            -------------
            c12 x12 | c22

            There are also certain rules forcing ocean/lake biomes to lose
            edges to mountains, and both of them to anything else, no matter
            what the original array value is. The actual biomes for tiles in
            the frame are semi-randomly interpolated from this edge spec.

                Additional feature_map information:
                The feature_map is a two dimensional structure dividing the world into 16 * 16
                world tile "feature shells" (and remember that there's a single tile wide shell
                at the end of each dimension, so a pocket world has a shell dimension of 2 * 2).
                These shells are loaded and unloaded dynamically, which means trying to access a
                shell that isn't the one in DF's focus (where the fortress/adventurer/pre embark
                cursor is) is invalid and can lead to DF crashing.
                The "features.feature_init" 16 * 16 structure contains the features of each of
                the corresponding world tiles within the shell. However, DF only loads the
                feature vectors for the world tiles in focus, although they seem to remain
                loaded until the shell is unloaded. Until loaded the vectors have a size of 0.
                Manipulation of the features is usually preserved as feature vectors are
                unloaded/reloaded, so spires can be elongated and rivers added, but some
                details, such as river fauna, seem to be generated on loading. Added features
                may not necessarily be reloaded at the vector index they were created at.
