[OSM-dev] patch: generate_tiles.py

[Armijn Hemel]

hi,

attached a patch which should provide some optimizations for
generate_tiles.py. Basically, it moves the checks if directories exist
per zoomlevel outside the actual tile rendering loop. This will only
check once per zoomlevel if the directory for that zoomlevel exists,
instead of up to several million times (depending on how many tiles you
generate of course :-P)
