The approach that I think will make sense for GIMP is not a global
working space, but as I outlined different working spaces for
different compositing/layer-modes. In GEGL each operation specifies
how it wants to work with the pixels. The implemented porter-duff
modes are in linear; the SVG variants should probably specify sRGB so
that an SVG reinterpreted as a GEGL compositing graph would render
correctly. In GEGL this does not only apply to compositing but also to
filters like blur, since blurring of a gamma corrected image also
leads to unexpected results.
