[Tilecache] metaTile configuration (and the Python imaging library?) - tutorial/documentation??

Perfect - thank you...

(and Chris @ MetaCarta for the same answer, with a gentle reminder to RFTM and on how to debug TileCache!  :-)   )

another point to check is if the PNG your mapserver draw is interlaced

FORMATOPTION "INTERLACE=OFF" in your OUTPUTFORMAT definition
