This is nearly done, but the ux needs some thought and work. I'm thinking something like this:

  • User clicks points to create the polygon. Optionally start with existing polygon.
  • Once created, vertices can be dragged.
  • Clicking on an edge will split it in two, creating an extra vertex.
  • Double-clicking on inside the polygon will delete and let the user create a new polygon.
