I'm just having a look at it as I want to create a map of Corsica for my
next vacation :-) 
By trying to add sea polygons by hand, I learned that the polygons must
not be too big - otherwise island are messed up (they are "overdrawn" by
the sea). 
Does someone know the reason for this and can specify what the maximum
size of a polygon (with holes) can be?

BTW: This seems to imply that multipolygons also can not exceed a
certain size - or is there already some code to divide resulting
polygons that are too large?  

Best wishes
