a rendering of world boundaries i have a prblem of created tiles. 
For zoom=0 the file generale_tiles.py with a own xml file create a right tile 
(256x256px) for all planet. but for zoom 1 and up all tile cointain some are 
(like south america o other part)repeted so when i view with my browser (sing 
openlayer) i see some part overlayed.
This is a xml file:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Map [
<!ENTITY % entities SYSTEM "inc/entities.xml.inc">
%entities;
]>
<Map bgcolor="#b5d0d0" srs="+proj=longlat +datum=WGS84 +no_defs"
