#478: There seems to be an offset in ST_Envelope or ST_Box2D

I apologize if this isn't a bug. Could be just something about OpenJump.
This may be our misunderstanding of how this is supposed to work, but we
imported a fairly random image into WKT Raster and when we look at the
ST_Envelope and original image in OpenJump, they don't seem to line up.
This isn't a georeferenced image.
So here is command we used to generate the sql
{{{
python gdal2wktraster.py -r wonderpostgis_banner.png -t wonderpostgis -o
wonderpostgis.sql
}}}
See attached the original image, the sql and the resulting openjump
snapshot
