NB: This document outlined a potential starting point for integrating
GIMP with GEGL, not a definite guide to the ideal color management
over time.

When editing multiple times, gimp should prefer to save the image with
a profile to
its internal working samplemodel and colorspace, thus making both load
and save conversions passthrough filters on repeated edits.
