 With on-the-fly-reprojection on, for a raster layer, if "Zoom to best
 scale (100%)" is used the map scale becomes 1:6517 instead of the expected
 1:9216 (for a 96dpi display). The raster is a 1:24000 250dpi scanned topo
 map.

 Works correctly if OTFR is off.

 This problem cropped up in the past 2 or 3 months.
