[MapServer-WMS]Raster with tileindex doesn't stretch when BBOX aspect ratio differs from width/height

[nsavard@…]

When raster uses a tileindex the image is not stretched if the
image width/height aspect ratio is different from the BBOX aspect ratio.  This
happens when MapServer is used as a WMS server.  I will
attached a tarball file of the data I'm using.

Example of a request:
http://server/cgi-bin/mswms_raster_query2?version=1.1.1&service=wms&
request=getmap&layers=grey&width=400&height=400

Also notice that when the "BBOX" parameter is added, the image is smaller than
the boundingbox.

Example:

http://localhost/cgi-bin/mswms_raster_query2?version=1.1.1&service=wms&request
=getmap&layers=grey&width=400&height=400&BBOX=0,0,80,60
