Revised order of #ifdef's and indentation in png_debug definitions of png.h bug introduced in libpng-1.2.34. Use png_memset() after png_malloc() of big_row_buf when reading an interlaced file, to avoid a possible UMR. Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined. Revised libpng*.txt documentation about use of png_write_flush(). Removed fflush() from pngtest.c. Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h Relocated misplaced PNG_1_0_X define in png.h that caused the prototype for png_set_strip_error_numbers() to be omitted from PNG_NO_ASSEMBLER_CODE builds. This bug was introduced in libpng-1.2.15beta4. Added a section on differences between 1.0.x and 1.2.x to libpng.3/libpng.txt Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles) Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow application code writers to bypass the check for multiple inclusion of setjmp.h when they know that it is safe to ignore the situation. Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress "shadowed declaration" warning from gcc-4.3.3. Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration" warning about a global "gamma" variable in math.h on some platforms.
