Implement "Place divisions in the map" game
Problems which should be fixed:
- placing countries with islands or "globes" is quite hard, because you don't
know where is the center, we should add something to the cursor to indicate
it
- just now it takes black (0,0,0) as frontier, but there are some maps which
use another color, we can add an extra tag to the XML to tell if some
color should be shown or not in this kind of game or edit the maps and make
sure that all the borders are black
- lots of problems which I haven't thought of :P
