[mkgmap-dev] [PATCH v3] Mp merge: generate-sea: bugfix for generate-sea=multipolygon

WanMil,

Good news - I don't think it's your problem. I disabled the sea
generation completely and the lines on the tile edges are still there.

Haven't a clue what's causing them (and I don't care because they don't
show up when I use generate-sea=polygons).

One issue that I don't think you can do much about is that mapsource
tends to show horizontal and vertical gaps between polygons when you
zoom out. They are a bit weird because they come and go as you pan and
zoom. Having polygons for sea (as opposed to having polygons for land,
which is what I have been using) means that you get more
artifacts visible when using mapsource. That's a shame but may well not
be a problem when viewing the map on a real gps.

Anyway, your new MP code is producing great results (and it's quick).
