Coastline

[andreasknoepfle]

Find a way on how to do a proper coastline in the island generation.

There should be at least 2 polygons resulting with one being the outer and one being the inner polygon.
Maybe you could even make other terrain appear on the page and return something like this:

{ 
  islands: [
    { 
      terrains: { 
        beach: [ ... the polygon points for the beach ... ],
        forest: [ ... the polygon points for the forest ],
        mountains: [ ... the polygon points for other terrain ... ]
      }
  ]
}
