Opening raster files in GdalUtility in their current CoordinateReferenceSystem

[marycarome]

Opening a raster file in GdalUtility with open(File, CoordinateReferenceSystem) and passing in the dataset's current CoordinateReferenceSystem (i.e. the dataset just needs to be opened) returns a dataset slightly different from the one returned by a direct call to gdal.Open(File)

This could be due to small differences in the WKTs (well known text) of the Dataset's SpatialReference and of the SpatialReference associated with the CoordinateReferenceSystem.

Could be caused by slight differences in WKT strings. We need a better way of figuring out, from GDAL, if an SRS/CRS is "close enough" to another SRS/CRS.
