Fixes bathymetry problems on turns or confluences, as well as abrupt riverbanks.

instead of the number of nodes.

Fix parameters for Simplex noise, to make sure the last octave has not a greater scale than 1
Also use a 401x401 grid instead of 400, so that there are 400 intervals

Position should be strictly beyond river threshold to be a river
Prevents some wrongly placed water pixels.

Re-organized the code. All polygon-related calculations go to polygons.lua.

Added an offset of 0.5 on terrain elevation
This prevents rounding errors and improves interpolation on nearly flat areas

Implemented variable river width.
Also changed the river data exported by terrain_rivers.py. They will not be compatible with what's generated by older versions.

More robust and faster code for grid twisting on the Lua side.
At chunkgen init, build a list of the polygons instead of calculating them for every node.
