When autosaving the georeferencer gcp points, we MUST use the original

raster file name for these and not the output raster file name The GCPs relate specifically to the ORIGINAL image, not the warped output exported after georeferencing. If we use the output file name for the .points file then when THIS georeferenced output is loaded into the georeferencer we get misleading location of source GCP points, as the pixel coordinates are from the ORIGINAL image, not the warped one.
