If you consider the whole image (including layers, metadata, etc.),
then the only lossless image format is XCF. All other formats drop
some information: PNG cannot save layers, TIFF cannot save all
GIMP parasites, etc. In fact, even the current XCF loses some
information if you consider that it does not record the full undo
history and the current tool contexts, but this is something that
most users accept.
So I think that the statement from Peter that singled out indexed
image formats and JPEG was slightly misleading (and this triggered
my initial reaction). Basically, only XCF would be "saved" and all
other image formats would be "exported".
