# mod_tile assumes file extensions are consisting only of lower-case letters, while we want them to be "o5m"
# we achieve that by rewriting the file extension to one we use internally for this ("ofm")
# However, we must only do that for levels 11 to 17 which are delivered via Tirex, levels 1 to 9 are static
# and delivered differently.
