[Gegl-developer] babl roadmap ever so slightly updated

[Øyvind Kolås <pippin gimp org>]

A note that the babl roadmap towards enabling use of multiple
working/sensor/target RGB spaces in a single GEGL graph has been
slightly updated. Now also mentions why accumulating floating point
errors if more conversions than desired happens isn't a real concern
with current photo technology sensor precision.
