[mapguide-users] Manipulating Maps in a Session, .NET API

[Kenneth Skovhede, GEOGRAF A/S]

There is no scale in the runtime map (MgMap).
When you request that the image is rendered, you supply dpi, resolution 
and either center/scale or extent.
You cannot store the scale or the center in the runtime map, you must 
store it locally in your client.
