    Use LCMS, not CTLCS for 32 bit float colorspaces · f51b30ac
    Halla Rempt authored
    This merges branch pigment-lcms2_rgbaf32-rempt. When lcms2 supports
    16 bit floating point numbers, the last two colorspaces will be
    moved from ctlcs to lcms, effectively retiring ctlcs. The technology
    was way cool, but it's easier to support all features in lcms.
    
    This also changes pigment:
    
    * if an icc-based colorspace factory is encountered for which there
    are no profiles, don't assert but warn and disregard the factory
    * previously, if the color conversion graph would encounter its
    base alpha 8 node, we would assert because there was no factory for
    alpha8.
    * the colorspace traits are now made complete and split out in
    separate files for easier editing.
    
    This also adds a bunch of more or less useful variations of colorspaces
    to the lcms2, as well as whole new YCbCr classes. For which there are
    no free profiles available, so users will have to provide those, for
    instance from the lcms2 website.

        Don't delete all the colorspace stuff on app exit
    
        It's faster and safer.

        Color Conversion System: don't assert if there is no profile
    
        For some colorspaces (ycbcr) there are no free profiles available. If
        the user wants, they can add a profile and the cs will work, but until
        that time, don't crash.

        Implement floating point versions of all supported color models
    
        This also adds ycbcr support using lcms2; however, users should bring
        their own profiles.

        pigment: rename the rgb traits to bgr traits
    
        The reason is that they actually describe a bgra pixel, not an rgba
        pixel and we need rgba traits for the floating point rgba color space.

        gray32f, rgba32f, xyza32, ycbcr8, ycbcr16 can be done using lcms2.
    
        Also remove the unused lmsaf32 profile.

        lcms color engine: add an experimental rgbaf32 colorspace
    
        This uses the new floating point capabilities of lcms2 to create a
        hdr rgba colorspace that automatically uses all the templated functions
        of pigment.
