No idea yet how to fix this. Enabling PNG copy would currently let quite a few PNG image types being copied (instead of going through the safe but slow read/write procedure), resulting in visually broken images (e. g., cs3n2c16.png from the PNG test suite). ------------------------------------------------------------------------
