 From Addendum 3 in MapGuide RFC 51 - Raster Re-projection
 http://trac.osgeo.org/mapguide/wiki/MapGuideRfc51

 If the RasterGridSize is close in size to the actual width or height of
 your image (e.g. a RasterGridSize that is ~50% of the height/width), and
 the raster re-projection is more than a simple affine transformation (e.g.
 LL84 -> World-Sinusoidal), then you will end up with a poor raster re-
 projection.

 One place you will commonly encounter this situation is with the Fusion
 Overview Map. This may also occur when your window size is very small.

 To address this, a few more configuration settings will be added to the
 serverconfig.ini. In addition to RasterGridSize, we will also add
 MinRasterGridSize and RasterGridSizeOverrideRatio.
