Tiling a Raster Image

Given: A georeferenced raster image encoded with bytes data.tif

1. Tile it: python gdal2tiles.py -r near -z '12-20' -w none data.tif (creates LODs 12 to 20 with nearest neighbor scaling, since the encoded values we tend to use don't play nicely with interpolation)
2. Fix the naming of the tiles so they conform to our standard: python manage.py tms_to_osm_tilenames --pyramidpath data (gdal2tiles names the y-coordinate by the TMS standard, while we use the OSM naming in our pyramids)
