Hi!

Theres seems like there are some troubles with layers at different scales when 
requesting a map in EPSG:900913). I have set up the mapfile in EPSG:32633 
(WGS84, UTM zone 33), and all the layers are as well sett to be in EPSG:32633. 
When requesting maps in in UTM zone 31 to 36 the layers switches at the right 
scales. The scale intervals could be is like this:

LAYER 1
   MINSCALE 2000000

LAYER 2
   MAXSCALE 2000000
   MINSCALE 800000

LAYER 3
   MAXSCALE 800000
   MINSCALE 100000

LAYER 4
   MAXSCALE 100000

When requesting a map covering approx the same area (see attached images), 
different layers are turned on in mapserver (shows as different level of detail 
in the maps).

Is there a workaround for this? I guess that the issue has something to do with 
how scales are calculated in mapserver.

PS! The same issue is present when requesting maps in geographic coordinate 
systems like EPSG:4326. The maps are generated with WMS GetMap requests.
