problem with MapServer global projection

[percy]

Hi John,
Do you have a Projection object defined in your Layer object, too?

You probably need something like:
   projection
      "init=epsg:4326"
   end
If you are using DD...

MS needs to know what coordinate system your data is in before it can
reproject it.
