Avoid potentially dereferencing NULL info_ptr in png_info_init_3(). Rearranged png.h to put the major sections in the same order as in libpng17. Eliminated unused PNG_COST_SHIFT, PNG_WEIGHT_SHIFT, PNG_COST_FACTOR, and PNG_WEIGHT_FACTOR macros. Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler (Bug report by Viktor Szaka'ts). Several warnings remain and are unavoidable, where we test for overflow. Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c Fixed uninitialized variable in contrib/gregbook/rpng2-x.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
