I wrote what I learned about this topic down in
<http://www.freeciv.org/~rfalke/grid_pics2/iso_maps.html> (reading the
html may be easier). This is mostly for people which haven't thought
about this topic. I tried to avoid implementation specifics in the
overview section.

Open points in my eyes are:
 - which form should be default (IMHO per performance)
 - which iso variants do we support (IMHO both)
 - in which form is wrapping defined? Do we support multiple wrapping
 forms (iso view form and non-iso view form)?
 - how can mapview code done in an easier way (IMHO with an
 intermediate form)
