Color management for a pic only with EXIF Interop
Firefox doesn't handle a color space of a picture only with InteropIndex correctly. <steps of reproduce> 1. open an attached JPEG, InteropIndex.jpg 2. open another attached JPEG, InteropIndexICCProfile.jpg 3. <reproduce> Firefox doesn't show two JPEGs as the same color. I confirmed it on this build: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0 ID:20161203030204 CSet: 557548714db55136b51e1129d649e2599797985f <expected result> Firefox shows two JPEGs as the same color. <comment> InteropIndex.jpg has only EXIF InteropIndex = R03, Adobe RGB. InteropIndexICCProfile.jpg is InteropIndex.jpg which ICC Profile for Adobe RGB is added in. Firefox seems to require ICC Profile in a picture to choose its color space. But most of cameras, including my Pentax K-3 making InteropIndex.jpg, write a JPEG picture only with EXIF InteropIndex, without ICC Profile. Firefox should choose a color space only with EXIF InteropIndex. Microsoft Edge handles EXIF InteropIndex effectively. Little cms apparently also does. https://sourceforge.net/p/lcms/mailman/message/19191688/
