Determine the current viewport(imgext) in map mode

[Eduard Witteveen]

Hello,

Currently i'm working on my own viewer to view a map(based upon a url).
I use mapserver only to generate the map image(mapserver has to functionate
stateless). When my viewer starts the image will be shown from the location:
  http://localhost/cgi-bin/mapserv.exe?mode=map&map=/ms4w/apps/test.map

In order to perform a zoom(i want to stay in the map mode),  i need to know
the current viewport. How can i query this?  (i need to know the current
imgext parameters, so i can determine the new zoom in my code)
I know that i could hardcode the imgext parameters in my application, but
i'd rather query this from the mapserver.
