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.

<comment>
In order to determine how biomes cross embark tile edges,
the rectangle framing an embark tile is split into 4 corners,
and 4 straight edge segments, using ranges measured in tiles:
+-/----/+
| /
/ * |
/ /
+-/-/---+
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.
For some reason DF provides for all edges of all mid level tiles
in a world tile, but not for the corners on the south and east
edges: for these you have to go to the next world tile.
This has some effect on the corners on the south and east edges of
the world where there are no adjacent tiles to get the data from.
There the rules are static: the biomes of corners are taken from
the easternmost and southernmost of the two touching corners.
The rules for corner determination when the biome_corner field has
specified a biome that's specified to yield as per the above seems
to be to first take the NW corner (0), then the NE (1) one, and
then the SW (2) one. If the selected corner doesn't exist (because
it's outside of the world) the same fallback corner selection is
used, with the exception of a northern row selection of NW (0),
where the home corner (3) is selected.

All 4 corners touching get the same reference (which determines the biome),
i.e. SE corner of the tile to the NW, SW corner of the tile to the
N, NE corner of the tile to the W, and the NW corner of the current
tile, as directed by the biome_corner value.

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.
