Description

+init=epsg:3857 should be default projection description.

Why:

  1. osm.xml/tirex pair will work faster, omitting useless reprojections (see http://trac.openstreetmap.org/ticket/4212);
  1. mapnik itself has some internal optimization that relies on +init=epsg:3857 as spherical mercator description;
  1. this will be one of the steps to get rid of all the "spherical mercator hell", see http://wiki.openstreetmap.org/wiki/Spherical_Mercator for the list of different names and definitions
