Oops, I may have spoken too soon. With your v3 patch in place, I made a
new map with generate-sea=polygons and not only are the lines still
there, all my sea has disappeared! 

Don't worry, I now think the lines between the tiles are always there on
my Baltic map and I just haven't seen them before because when you use
generate-sea=polygons you get polygons covering all of the map. But
when you use generate-sea=multipolygon, there are no land polygons and
so the lines show through from underneath. Now why they are there, I
don't know at the moment (I don't think it's the fault of the
MP code).

However, there is still a problem in that with your v3 patch in place,
I no longer get any sea polygons visible when I use
generate-sea=polygons. I wonder if the change you made to the size of
the sea polygons is responsible for that? Could you please change that
code so that it only produces the over-large sea background when
generateSeaUsingMP is true?

Thanks,

Mark
