A GimpImage is a lot more than stacks | of layers and channels. It has an awful lot of GIMP specific | properties that you certainly don't want to add to GEGL.

Do you think my roadmap is at least reasonable, except for these details? - -- Dan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFAArtSad4P1+ZAZk0RAsSUAJ0f2TSZmPqrmYDqcLIN7aMDviHHjQCfS9T5 FWbXcj0u9VBjeBn7BLOn1so= =rt9E -----END PGP SIGNATURE-----
