reg. no-trim: it is difficult to say what splitter should do if you don't specify a bounding polygon. Do we only care about holes that are enclosed by other tiles or do we also not want gaps between two tiles? The latter typically happens when you have some islands . The tiles with islands are not trimmed, but tiles between them may be trimmed. I guess this is also not wanted? Hmm... it's hard to say. ;) Maps looks nicer in MapSource&Co with --no-trim, if you generate sea. On the other hand it could cause problems, because coastline-nodes aren't counted and so a tile could get to big for mkgmap. Eg. if you generate a map of Italy you may get hole coastline of Adria. So in this case it would be better not to extend the map like --no-trim did.
