Nico Weber 07fe8b8d0a icc: Add a --debug-roundtrip flag ...

With this, we convert a bunch of random colors to a
profile's profile connection space and back, and count
how many u8 colors make it through unchanged.

With this, you can do something like:

    for f in ~/Downloads/Adobe\ ICC\ Profiles\ \(end-user\)/*/*.icc; do
        echo $f
        Build/lagom/bin/icc --debug-roundtrip $f
    done

to test conversion through a bunch of profiles. These profiles are
available at:
https://www.adobe.com/support/downloads/iccprofiles/iccprofiles_win.html

...which ultimately leads to:
https://download.adobe.com/pub/adobe/iccprofiles/win/AdobeICCProfilesCS4Win_end-user.zip

(Or use `Build/lagom/bin/icc --debug-roundtrip -n sRGB` to test the
built-in sRGB profile.)
