RGBA is just a notation for a storage format, it says nothing about how the components should or should-not-be interpreted. The gimp, however (and emacs) needs to worry about such things regardless, since in the end it's in charge of what the user sees; hopefully there's helpful meta-data which says what to do... -Miles -- We live, as we dream -- alone....
