It was a few years when I implemented that, so we would need to try again to be
sure. I believe that the issue was about resampling a new image where the
destination is expected to have a given "gridToCRS" transform, which is okay
only if the image get exactly the size we expected when we computed that
"gridToCRS". Having an image one pixel bigger than expected means a shift of 10
km in raster where pixel are that size (the Ocean data I was working on).
