[Freeciv-Dev] (PR#7287) Extended Topologies

["Marcelo Burda" <mburda@xxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=7287 >

Hi,
there is a tested version of the init_topo code working in 
map-iso-coordinates, the maview is extended to more general topologies 
and tuned for map-iso-coordinates.
uranus is there and mobius too, (i kip uranus but i thinck it need to 
disapear later to limite a litle the number of topos, uranus is exact 
the some topologie than classic, but we can wait qincuncial patch for 
it)

client: gtk, gtk2 and xaw

the generator fixes for poles are workin in iso-map-coordinates too and 
make nice poles for all topos

math is optimized but iso-map-coordinates are heavy impact where 
actived, probably we can write wraps directly in map-coordinates, 
spetialy in normalize_map_pos, the virtual function can help there to 
have separated code for it.
this is a very hard work but my optimized model can help. we need thinck 
at it. Topologies are near zero speed impact, that is not a problem.

we make 3 optimizations
1)some virtual function to avoid cast and make clear code

2)normalize only normalize near orbit pos, far orbit stop with asserts. 
(this force coders to never forget a normalize)

3)normalize is retarded to preserve information for more general 
topologie( code are forced to use carrefully normalize) but this last 
point are important for quincuncial. not for the topos included there.

at this point i am waiting the patch to be totaly or partial assepted.

TODO
eventually code normalize directly in map-coordinates for the 
iso-map-coordinate

alow user to set directly xsize and ysize is not good and need to be 
disalowed.

test, and more test.

I wait for your comments.
