372,[Mapserver]36 to 40 converstion OVERLAY Objects are LOST!,thorne@…,dmorissette,"{{{
I have confirmed that when converting a simple 36 map file to 40 with OVERLAY 
Objects in the class, the OVRLAY Definition is not put into a second Style 
object for that class. It is lost, during the conversion.

eg.

INPUT for Converstion ->Mapserver 36 Class Definision:
    CLASS
      NAME ""Interstates""
      EXPRESSION ""Interstate""
      SYMBOL ""circle""
      COLOR 51 51 51
      SIZE 4
      OVERLAYSYMBOL ""circle""
      OVERLAYCOLOR 220 0 0
      OVERLAYSIZE 2
    END
OUTPUT from the Conversion -> Mapserver 40:

    CLASS
      NAME ""Interstates""
      EXPRESSION ""Interstate""
      STYLE
        SYMBOL ""circle""
        COLOR 51 51 51
        SIZE 4
        MINSIZE 1
        MAXSIZE 100
      END
    END

WHAT IT SHOULD BE:

    CLASS
      NAME ""Interstates""
      EXPRESSION ""Interstate""
      #-----------------
      #THE OVERLAY STYLE
      #-----------------
      STYLE
        SYMBOL ""circle""
        COLOR 51 51 51
        SIZE 4
        MINSIZE 1
        MAXSIZE 100
      END
      #-----------------
      #THE BOTTOM STYLE
      #-----------------      
      STYLE
        SYMBOL ""circle""
        COLOR 51 51 51
        SIZE 4
        MINSIZE 1
        MAXSIZE 100
      END
    END

Note: Notice that the Overlay Style is positions on top of the original symbol 
style. I am not sure if this is an issue when building your class where you 
have to place the styles in a specific order. If it is we should have a 
STYLEORDER Object, maybe (?)....
