I'm sure I saw an email from WanMil recently that said there already is 
  code in mkgmap that can test to see if an object is a closed polygon. 
  If, so, then this code could be re-used and --add-pois-to-areas could 
be run before the style file processing.  Whilst I'm helpfully palming 
off work to others more skilful than myself, could whoever does this 
also add some logic to make sure the resultant POI is always placed 
*inside* the polygon? :)
