[Freeciv-Dev] (PR#9135) Roadstyle 2

["John Bauman" <john@xxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=9135 >

This implements roadstyle 2, i.e. a method similar to that used in Civ 3,
where there is a graphic for every combination of exiting roads for a tile,
and another for every combination of exiting rails.  This does require 512
new graphics (2 * 2**8), but it does look better than before, with all the
extra possibilities.  Attached are a patch and two spec files that can be
used with (scaled-down) road and rail graphics from Civ 3.  This would be a
good use for that "fractal tile generator" mentioned not long ago.
