Thanks for the summary, I am sorry I missed the summit, but the Twins 
were playing so we did baseball instead.

- Paul Spencer and I also talked about "magic projection" support. Many 
formats have projection information embedded or alongside, so having to 
redundently specify them in the map file is not the most user-friendly 
approach. Like the "wms_extent", projection blocks should really only be 
required "as necessary". I think this can be done relatively easily, by 
adding some projection setting code into the LayerOpen area of each 
driver, and agreeing on some heuristics:

o If there is a PROJECTION in the map file, then don't overwrite it.
