I'm new to libpng and trying to figure out if libPng supports scRGB (16 bit per pixel) encode/decode, From the readme it is not very obvious to me if it supporting scRGB which is the wide-gamut 16 bit depth. And if yes, is this a new feature added in recent builds only, or has been available for a long time. We have a pretty old version of libpng 1.2.8 in our system, and would like to know if this is already supported in that version or not as well
