PNGv3 colourspace precedence rules conformance This is a major change required by the new PNGv3 colour chunk precedence rules. It **does not** change the libpng API (png.h) however it changes the following handling of PNG files: IFF the PNG file contains colour space information it changes from the libpng v3 behaviour to the now compulsory PNG v3 behaviour: 1) libpng no longer invalidates colour space chunks because they are inconsistent. 2) libpng no longer responds to the "png_get_" APIs positively if they are not present in the PNG but can be deduced from the colour space chunks that are present.
