strange, why white rectangles? since mkgmap:skipSizeFilter=true - this 
didn't happen to me anymore. Anyhow great improvement. Those sea tiles 
were cut far too small...

I have to try, but probably now higher min-size-polygon values, will 
work again (well the new depending on resolution min-size filter isn't 
redundant by this either - still a good solution)
