Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco to put png.h and pngconf.h in $prefix/include, like the other scripts, instead of in $prefix/include/libpng. Also revised makefile.sco to put them in $prefix/include/libpng12 instead of in $prefix/include/libpng/libpng12. Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin and contrib/pngminim/*/makefile Relocated png_do_chop() to its original position in pngrtran.c; the change in version 1.2.41beta08 caused transparency to be handled wrong in some 16-bit datastreams (Yusaku Sugai). Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt (revising changes made in 1.2.41) Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngset.c to be consistent with other changes in version 1.2.38. Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr in pngtest.c Send comments/corrections/commendations to png-mng-implement at lists.sf.net (subscription required; visit https://lists.sourceforge.net/lists/listinfo/png-mng-implement to subscribe) or to glennrp at users.sourceforge.net Glenn R-P
