Yes, the mixing up of mod_tile and renderd into one is a bit
non-intuitive for those using Tirex.

Thing is, it is a bit cumbersome to configure all the mod_tile features
via the Apache config. Apache has these TAKE2 and TAKE3 macros that you
can use to process AddTileConfig lines; I believe when Kai introduced
MIME settings he created a new AddTileMimeConfig for that using three
arguments instead of the two we used before.

What we should really do is switch to AP_INIT_RAW_ARGS and then have a
config line that goes

AddTileConfig uri=/tiles path=/my/tiles/somewhere maxzoom=20 minzoom=3
mimetype=sometype cors=whatever

etc., where the key-value arguments are parsed by the function itself
and not by Apache.

Bye
Frederik
