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.

Version: 3.4.0 → 3.5.0

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
