Re-projected raster does not look good in Fusion Overview Map (and really small windows)

Description

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.
