Hmm, I don't think we would want a chunk of code as big as I suspect
would be needed for jpeg2000 to be in GTK+ itself. The builtin loaders
for GTK+ are for more or less simple formats that are basically
just wrappers around the bits.
If writing a jpeg2000 library was something that you were interested
in, I'd suggest writing it standalone so everybody could use it,
then include a gdk-pixbuf loader using your library as part of the
package.

BSD code with the advertising clause is generally speaking not suitable
for distribution with GTK+, since it is not GPL compatible.
For an independently installed loader, my personal feeling is that if
you write a independently installed pixbuf loader that:
A) Uses only symbols from the publically installed GTK+ headers
B) Does not incorporate code from GTK+
C) Is not written as a paraphrase of code in GTK+
Then it is not a derived work of GTK+, and thus could be under any
license, even a proprietary license.
(This is not a legal opinion, though I know of lawyers that have
expressed similar opinions in cases that to me seem similar.)
