GDAL provider doesn't return spatial contexts

Description
When loading a data source that does not have an associated coordinate system, the GDAL provider does not assign the extents of the image to the spatial context, even though they are known. This makes creating MapGuide maps for images that don't have coordinate systems assigned very painful.
See: MapGuide #740 for details
It would be great if this could be addressed in a 3.4 maintenance release if there is one.

See TracTickets
for help on using tickets.
the correct link for the MG bug is http://trac.osgeo.org/mapguide/ticket/740
using GeoTIFF from http://www.unearthedoutdoors.net/global_data/true_marble/download
the CS is always returned as Default :: LOCAL_CS["*XY-MT*",LOCAL_DATUM["*X-Y*",10000],UNIT["Meter", 1],AXIS["X",EAST],AXIS["Y",NORTH]]
The GDAL provider is now working reliably if you use CS overrides with MG 2.2 and follow the wiki directions from Trevor
