[mkgmap-dev] [PATCH] Option to extend sea sectors at extract borders

Hi, this patch (against 1485) adds a new option for generate-sea: "extend-sea-sectors" If this option is set, coastlines not reaching the borders of a map will be extended with a point at the nearest border. This prevents strange things happening at the borders of geofabrik extracts. See attached pictures of turkey created with options "polygon" (just_polygon.png), "polygon,no-sea-sectors" (noseasectors.png) and "polygon,extend-sea-sectors" (with_patch.png). Would be nice if someone could test and merge it. Thanks, Ronny
