 /* About the ICC profile header "Platform" tag:
  * 
  * When creating a profile, LCMS checks to see if the platform is 
  * Windows ('MSFT'). If your platform isn't Windows, LCMS defaults 
  * to using the Apple ('APPL') platform tag for the profile header.
  * 
  * There is an unofficial Platform 
  * cmsPlatformSignature cmsSigUnices 0x2A6E6978 '*nix'. There is, 
  * however, no LCMS2 API for changing the platform when making a profile.
  * 
  * So on my own computer, to replace 'APPL' with '*nix' in the header, 
  * I modified the LCMS source file 'cmsio0.c' and recompiled LCMS:
  * #ifdef CMS_IS_WINDOWS_
  * Header.platform= (cmsPlatformSignature) _cmsAdjustEndianess32(cmsSigMicrosoft);
  * #else
  * Header.platform= (cmsPlatformSignature) _cmsAdjustEndianess32(cmsSigUnices);
  * #endif

 /* Sample command line to compile this code:
  * 
  * gcc -g -O0 -Wall -o make-elles-profiles make-elles-profiles.c -llcms2

  * You'll see a lot of harmless warnings about unused variables. 
  * That's because I included variables for profiles that the code 
  * doesn't actually make, in case you might want to make 
  * these profiles for your own use.

  * "fit" meaning "could be calibrated to match".
  * Adobe does still distribute a ColorMatchRGB profile.
  * Making this profile using the D50_romm_doc white point that is used 
  * in other old V2 profiles (ProPhoto, WideGamut)
  * doesn't make a well behaved profile,
  * but the resulting profile is very close to the Adobe-supplied version. 
  * Using the prequantized primaries makes a profile that's just as close
  * to the Adobe-supplied version and in addition is well behaved.
  * Unless you have untagged images created on a PressView CRT, 
  * there is no reason to make or use this profile.
