Update to 1.15. patch-ab has been sent upstream.

New features

  Black preservation on CMYK-> CMYK transforms
  Ability to set adaptation state of observer on absolute colorimetric transforms.
  A rather advanced feature. Actually it only allows No adaptation (d=0) and observer fully adapted (d=1)
  lcms can now "fix" some broken 8-bit profiles that have gray axes misplaced.
  icctrans can now read CGATS/IT8 files.
  improved tifficc with tiff Lab8 support

LPcmsGAMUTEX cmsReadExtendedGamut(cmsHPROFILE hProfile, int index);
void         cmsFreeExtendedGamut(LPcmsGAMUTEX gex);


New tags supported

       icSigColorantTableTag		    LPcmsNAMEDCOLORLIST
       icSigColorantTableOutTag         LPcmsNAMEDCOLORLIST
       icSigCalibrationDateTimeTag	    const struct tm*


New flags:

cmsFLAGS_PRESERVEBLACK
cmsFLAGS_GRIDPOINTS(n)


And of course some bug fixing.
