    widget-factory: Add tests for loading color profiles
    
    I figured out how to generate them, yay:
    
      cmsHPROFILE lcms_profile;
      cmsToneCurve *curve[3];
    
      curve[0] = cmsBuildParametricToneCurve (NULL, 4, (double[5]) { 1.0, 0, 0, 0, 0 });
      curve[1] = cmsBuildParametricToneCurve (NULL, 4, (double[5]) { 2.4, 255.0 / 15 / 1.055, 0.055 / 1.055, 
0, 15./255 });
      curve[2] = cmsBuildGamma (NULL, 2.4);
      lcms_profile = cmsCreateRGBProfile (&(cmsCIExyY) {
                                            0.3127, 0.3290, 1.0
                                          },
                                          &(cmsCIExyYTRIPLE) {
                                            { 0.6400, 0.3300, 1.0 },
                                            { 0.3000, 0.6000, 1.0 },
                                            { 0.1500, 0.0600, 1.0 }
                                          },
                                          curve);
    
      cmsSaveProfileToFile (lcms_profile, "foo.icc");
    
      cmsFreeToneCurveTriple (curve);
      cmsCloseProfile (lcms_profile);
