[Freeciv-Dev] Hex tileset

[Artur Biesiadowski <abies@xxxxxxxxx>]

Do anybody have good idea for how to make hex tileset ? I'm worried
about 'neightbour' modifications - in current square tileset it is
handled by using 16 (2^4) versions of each terrain. With hexes it would
require 64 (2^6) of them - way too much. So it has to be handled in
other way, question how ?

I'm thinking about overlay images - either 6 of them, or 10 (get 4
versions of upper and bottom corner each, because with flattened hexes
it might be too small area to get them right independly).

Maybe something like adding 3 pixel wide border, overlapping neighbour
hexes with decreasing alpha at each pixel to merge colors with other
terrains would work ?

Anyway, it is nothing critical, everything should be playable even
without border overlays, but if somebody has a good idea...
