Ah! ;) Still gimp would not support uncommon errors by giving the user more

This is windows thinking a lot. Not implementing something because it is
costing a lot of time would be understandable, but not offering features
because the user might be too dumb is never a good idea (IMHO).

Make sa lot of sense to me. TGA images are a common format for programs
that have special requirements (like a special layout).

Well, we could also always write png's with compression=9, for example, as
the resulting image is the same in all cases ;)

A very good reason _not_ to is that it might be pretty unimportant, so
coding these features might be a waste of time...
