shpindex depth

As Mapnik's shapeindex utility does not have optimized defaults, I matched the Mapserver depths used exactly (shptree notes):

 shapeindex -d 21 building.shp
 shapeindex -d 16 contour-0.shp
 shapeindex -d 17 contour-1.shp
 shapeindex -d 17 contour-2.shp
 shapeindex -d 17 contour-3.shp
 shapeindex -d 17 contour-4.shp
 shapeindex -d 15 contour-5.shp
 shapeindex -d 17 contour-6.shp
 shapeindex -d 17 contour-7.shp
 shapeindex -d 17 industry.shp
 shapeindex -d 10 motorway.shp
 shapeindex -d 15 point-labels-for-geometry.shp
 shapeindex -d 18 point-labels-no-geometry.shp
 shapeindex -d 14 ramp.shp
 shapeindex -d 14 road.shp
 shapeindex -d 16 settlement.shp
 shapeindex -d 16 track.shp
