When tile border is on a raster border the tile border isn't properly rendered.[[BR]]
Here is an example :[[BR]]
Wrong : http://i455.photobucket.com/albums/qq279/ghurdyl/work/mapnik-1.png (with mapnik & gdal plugin) [[BR]]
Right : http://i455.photobucket.com/albums/qq279/ghurdyl/work/gqis.png (with QGis)[[BR]]
[[BR]]
Raster are 4096x4096px png generated with mapnik from shape files data. (and an additional .pgw world file)[[BR]]
They are generated in such a way that there are exactly 256 small tiles (16x16) of 256px inside one raster[[BR]]

On the wrong images, tiles have been generated from the rasters with mapnik (and gdal plugin ) and the border of wrong tiles are exactly on the border of rasters.
