[mapserver-dev] variable substitution for projection

[Zach Aller]

that seem's to have done the trick sort of now i am just wondering if i can
set that for a specific layer i tried

map.layer[layername].projection

but that did not seem to work. Setting the map projection will probably be
fine for our project at least for now.
