    Add adaptation state slider.

    This allows you to set whether or not to adapt the white point, that is,
    to set the white point to the screen white(full slider) or to convert all whiteson screen to the white point of the profile when using absolute colorimetric
    as intent.

    This is useful to simulate paper-colour.

Date:   Thu Jun 23 13:37:49 2016 +0200

    Disable softproofing in floating point spaces.

    There's a bunch of little niggling bugs that crop up when soft proofing
    in floating point spaces, amongst which the inability of the proofing
    mechanism to see floating point values higher than 1.0 fall outside of
    the gamut of the color space, let alone recognising whether it can go
    inside the gamut of the proofing space.

    See also http://ninedegreesbelow.com/bug-reports/soft-proofing-problems.html

    For now, it's best to disable softproofing on floating point spaces.
    Might need a more official check, though.

Date:   Tue Jun 21 20:21:15 2016 +0200

    Refactor the proofing transform system for better caching.

    This now makes the transform separately from the actual transforming,
    which means it's easier to cache and to update. Softproofing is now
    gone from usable to user-friendly.

    Still needs saving/loading and little setting-bugs fixed.

commit 8371c417
Author: Wolthera van Hovell tot Westerflier <griffinvalley@gmail.com>
Date:   Tue Jun 21 18:20:48 2016 +0200

    Enable Gamut color and proofing intent.

    The image now stored proofing intent, and the monitor intent is the general
    rendering intent.

    This also allows us to set the gamut warning color, however, for updating
    you currently need to switch profiles as well. I'll make a seperate
    generateSoftProofingTransform function, to cache the transform better, so it's
    easier to update.

    This does cause a significant speed-up, but it's a bit fiddly.
    Regardless, the speed-up is enough to make this usable.
