[2020] increase FOW reveal radius based on altitude.

In the past there have actually been technical limitations on how much of the map can be revealed. There were versions where you would run out of space for revealed parts of the map, and the oldest parts you'd revealed went back to the 'fog of war' state. Hopefully that's fixed now, but if not, it probably explains why they're stingy about how much is revealed.

This still happens. On the server-side it's adjustable to an extent, but if the map file size for the player map gets too large, it will cause sync issues.
The default is 131072 chunks. I have tested doubling this up to 262144, and have not had any issues, but much larger and the client will begin to de-sync from the server when it's filled up.(Have tested up to a 16k map size, and had real hopes on a 12k map size working out better.)

There was a hard limit to the size of the file, and I believe that has been removed. Just need more map optimization to unlock that.

Note that in an 8k map there are 262,144 chunks. Navezgane has 147,456 chunks.
