 I was messing around swapping around parameters to see if I could get 8bit
 PNG (yes I know it's not supported in GetMapImage) and found that entering
 PNG8 into a GetMapImage call caused my IIS worker process to die, with an
 error in the System Application log, but none in the MapGuide logs.
 Here's a sample of the request I made:

 {{{
 http://localhost/mapguide/mapagent/mapagent.fcgi?session=3b5ee024-0000-
 1000-8000-
 000c293f205f_en_0A0A6EC10AFC0AFB0AFA&mapname=Sheboygan&operation=GETMAPIMAGE&format=PNG8&version=1.0.0&ts=1195850858076&locale=en&setdisplaydpi=96&setdisplayheight=1128&setdisplaywidth=1882.5&setviewcenterx=-87.71854751863403&setviewcentery=43.75168236754095&setviewscale=7759.005619599771
 }}}

 This kind of call should not be allowed to fail in a way that causes what
 is essentially a DOS vector.
