This discussion is about the problem of double gamma correction that you reported. By all means raise other issues if you wish, but they were not raised in a clear way before your latest message. The double gamma correction issue is only a side aspect, "fixed" easily enough. In that case, how about if we fix that now? At least we will get correct display. The other present problems seem (from all I can tell from your message) to cause only slowness. That would be trivially solved by ripping out the gamma correction the PNG library does. We don't want to change the PNG library. We want to use it unmodified. Can you find a solution to this one problem that invoves changing Emacs and not the PNG library?
