[Freeciv-Dev] New River Generator

[Erik Sigra <freeciv@xxxxxxx>]

Hi,
after a lot of testing of the various incarnations of the riversail patch, I 
felt the urge to actually code something myself. Since I have special interest 
in rivers and have reported bugs in the river generation, my decision was 
simple. I completely rewrote the river generator. To show what I mean, I made 
some before/after screenshots:

Freeciv with smallest map, set rivers 200:
==========================================
Before: 
<ftp://ftp.freeciv.org/freeciv/incoming/old_fc_rivers_smallest_map_200_rivers.png>
After: 
<ftp://ftp.freeciv.org/freeciv/incoming/my_rivers_smallest_map_200_rivers.png>

Freeciv with smallest map, set rivers 338:
==========================================
Before: 
<ftp://ftp.freeciv.org/freeciv/incoming/old_fc_rivers_smallest_map_338_rivers.png>
After: 
<ftp://ftp.freeciv.org/freeciv/incoming/my_rivers-smallest_map_max%28338%29_rivers.png>

Freeciv with smallest map, set rivers 1000:
===========================================
Before: 
<ftp://ftp.freeciv.org/freeciv/incoming/old_fc_rivers_smallest_map_max%281000%29_rivers.png>
After: see previous after

Freeicv with 100x50 map, set rivers 1000:
=========================================
Before: 
<ftp://ftp.freeciv.org/freeciv/incoming/old_fc_rivers_100x50_map_max%281000%29_rivers.png>
After: 
<ftp://ftp.freeciv.org/freeciv/incoming/my_rivers_100x50_map_1000_rivers.png>

This should fix <http://www.freeciv.org/cgi-bin/bugs?findid=537> and partially 
<http://www.freeciv.org/cgi-bin/bugs?findid=538>

What do you think? Any interest?
