As #1 to optimize the memory used by the ground.

Otherwise get on my old VAIO:

radeon: Failed to allocate a buffer:
radeon:    size      : 1134551040 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 2
radeon:    flags     : 0

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

To solve this issue uses the old_vaio branch.

This Python script allows us to know the biggest drop between a tile extremity and another (without considering its diagonal).

Python script:

import os

path = 'Extensions/LemnosLife/Map/Altis/Ground/'

os.chdir(path)

biggestDrop = 0

def getFloat(s):
    return -100 if s == 'N' else float(s)

for _, _, files in os.walk('.'):
    for file in files:
        with open(file) as f:
            lines = f.read().splitlines()
        for line, lineBelow in zip(lines, lines[1:-1]):
            columns = line.split()
            columnsBelow = lineBelow.split()
            for column, columnBelow in zip(columns, columnsBelow):
                column = getFloat(column)
                columnBelow = getFloat(columnBelow)
                drop = abs(column - columnBelow)
                if drop > biggestDrop:
                    biggestDrop = drop
            for column, columnRight in zip(columns, columns[1:-1]):
                column = getFloat(column)
                columnRight = getFloat(columnRight)
                drop = abs(column - columnRight)
                if drop > biggestDrop:
                    biggestDrop = drop
    break

print(biggestDrop) # 16.17
