GIMP kills the GeoTiff tags.  In earlier versions it would produce a
huge stack of error message windows when loading, complaining about
unknown tags, but now in ver 2.2.15 it just gives 3 errors per
GeoTiff which is  manageable.  I load my GeoTiffs in GIS software
first to save the geo data before editing in GIMP, so I can then
reload it using the data and have my GIS restore the GeoTiff tags.
