The compiler + performed an optimization which is safe but then warned about it. + Changing the type of 'palette_number' in pngvalid.c removes the warning. + Improved efficiency of new do_check_palette_indexes() function. + Don't check palette indexes if num_palette is 0 (as it can be in MNG files). + Include zlib.h in contrib/gregbook and contrib/visupng examples.
