    Add gamut point calculation thingy.

    This allows us to investigate CMYK and other cLUT only colorspaces in the colorspace browser.
    Also good for future gamut checking.

    Things that don't work:
    * Anything but 8bit colorspace, proly due to architecture stuffs. Maybe use from normalised instead
    of quint8 data...
    * Matrix profiles still default to relative colorimetric, which is kinda annoying
    * Need to investigate how to get the correct conversion flags over.
    * XYZA32bit float doesnt work...?

    Other:
    * Need to clean up
    * Need to check if I can get whitepoint/colorants simplified into the cs.
    * Need to see if this is also possible for the trc.
    * Maybe investigate boundary-checking-thingy for CMYK.

    There are some more places where a similar change would be good,

    normalize).

    Disable subpixel precision in the color smudge brush only for smearing mode

    Auditors: rempt, dkazakov, timotheegiet

    Original bug that caused the initial method was 327235, and that was only for
    smearing mode. In dulling mode the lack of subpixel precision is very obvious,
    while in smearing mode it isn't.

    Therefore, I propose we only disable subpixel precision for smearing mode.

    Experiment with linearising color selector

    Also doesn't work because linearisation function is too slow

    Experiment with HDR Values for the lighter/darker buttons

    This doesn't quite work yet, because HSY only really works in a 0-1.0 sceme

    Color manage darker/lighter, add actions for sat/desat/hue

    This still needs a lot of work.

    * It's all linear, we need to crunch the luma.
    * It's not working for XYZ/YCrCb/LAB properly yet. This'll require LCH/xyY
    * Hue-clockwise has issues.
    * QVector <double> needs to become QVector <float> for consistency.

    Add basic Tone Response Curve widget.

    It is based on receiving QPolygons filled with points, so it's cm agnostic.

    TODO:
    * Document
    * Cleanup
    * Move elements about(rgb to the tooltip of the tongue widget?)
    * Maybe render a grayscale in a given colorspace for the TRC widget?
