I have no chance of remembering more than what is in the code and comments for code that I wrote close to a decade ago, I'd suggest searching for the constants used in babl and see if the pages that turn up in a search result provide some rationale :) Thank you for your continued interest in reviewing some of the fundamental core bits. /Ø _______________________________________________ gimp-developer-list mailing list gimp-developer-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gimp-developer-list
