We need to eliminate blank tiles when we generate the transit overlay (or symlink them to a single blank tile?). Code to do this is at http://trac.mapnik.org/ticket/655 and http://mapnik-utils.googlecode.com/svn/example_code/check_for_blank_tile/test.py

This will reduce dataset size. I'm partway into level 18, and my dataset is up to 1.7G, primarily from blank tiles.
