[Talk-ca] Sinking islands...

[G. Michael Carter]

  I was importing data in the Georgian Bay area and I noticed 
something.   If an island is natural=land it renders in mapnik as white, 
regardless of the outer multipolygon.   if you have natrual=wood or 
possibly others, it sinks if it's not role=inner.

This is at least what I've observed so far.   It's rather hard to figure 
out when the mapnik tiles get cached and don't refresh in a timely 
fashion. :-)
