media-gfx/gnome-photos-3.16.0 has dependencies on gegl and babl which are still 9999
There is no existing release of gegl-0.3 that I could find yet.
Pushed in the overlay this afternoon. It is very annoying but we need to depend on a gegl snapshot which is a new slot yet the library is not slotted in tree. Anyway, it will be dealt with in time.
gnome-photos build with the snapshot and it didn't break gimp so we seem to be ok.
