[mapserver-users] Is mode=tile always epsg:3857?

[Jeff McKenna]

Thanks Rich and Mike, I've done some more local tests and given some 
much needed love to the mode=tile documentation, so hopefully these 
questions are prevented in the future.  Let me know if you notice 
anything else.  https://mapserver.org/output/tile_mode.html
