[gimp/alxsa-image-simulation-intent-bpc] core: Add simulation intent and BPC to GimpImage




commit f7fd7d885d0725848385f62c7a9003ac45961ada
Author: Alx Sa <cmyk student gmail com>
Date:   Wed Aug 10 15:01:15 2022 +0000

    core: Add simulation intent and BPC to GimpImage
    
    Adds a simulation_bpc and simulation_intent to GimpImage to allow
    plug-ins to access it
    for CMYK import/export.
    Four pdb functions were added to enable this access:
    image_get_simulation_bpc (), image_set_simulation_bpc (),
    image_get_simulation_intent (), and image_set_simulation_intent ().
    Next, it updates menu options and code to support GimpImage's
    internal simulation intent and bpc.
    New 'simulation-intent-changed' and 'simulation-bpc-changed signal
    are emitted via
    GimpColorManagedInterface so that relevant tools
    (such as the
    CYMK color picker, GimpColorFrame, and future pop-overs)
     are aware of these changes.
