[mapguide-users] Fusion and Themed Layers - usability

[Paul Spencer]

It does it automatically and is returned from LoadMap.php where the  
image is and which layers/scales are included plus the CSS offset.   
Dynamic layers (ones added after the map is loaded) don't have an  
entry so their legend icon works the old way.

Cheers

Paul
