[Freeciv-Dev] [PATCH] Tori, rectangles and cylinders. (PR#1048)

[Gaute B Strokkenes <gs234@xxxxxxxxx>]

Having grown tired of the discussion on this lately, I decided to
forge ahead and actually implement some of what has been discussed
lately.

This patch does the following:

* Add support for rectangles, cylinders (both ways) and tori to the
  various coordinate manipulation functions.

* Add a field top of type enum topology to the civ_map struct to
  control which version is used.

* Extend the GTK overhead view and minimap code to cope.  (I also
  eliminated all uses of map_adjust_[xy]).

Note that map.top is unconditionally set to TOP_XCYLINDER in
map_init(), so that no incompatibilities are introduced even though no
capstring has been added or all the clients updated.

Next: Xaw and the isometric view code.  Add isometric versions of the
topologies.
