I'm currently working on a patch to retrieve the projection info from
the map definition for MapGuide. The problem is that MG uses WKT and
OpenLayers/Fusion uses EPSG codes and MG doesn't always have an EPSG/WKT
mapping available. So I will be implementing this so that if MG returns
a valid EPSG code it will use that, otherwise it will take a value from
the ApplicationDefinition file, and if there still isn't an EPSG code
available then the projection will be set to the OpenLayers default of
EPSG:4326.

Im trying my hand at some Open Layers programming. I'm trying to set the maps
Coordinate system to match Mapguides, So I decided to peek into Fusion....
One thing for the life of me I can't find is where fusion sets the OpenLayer
Maps Coordinate system. I know Open layers uses Proj 4, and Mapguide Can use
both cs-map and Proj4...I know how to get the coordinate system Description
out of Mapguide...But how do I push it back into OpenLayers Using my PROJCS
system...
Or worded Much simpler...How/Where does Fusion do this to openLayers...I
want this to work on anymap...so I don't want to hard code a EPSG code into
it, and several users will have Non PROJ4 coordinate systems, like Local
County Coordinate systems that CS-MAP allows them to use...
ANYONE?
