-libpng-1.0.3:
-
- Replaced and extended code that was removed from png_set_filler() in 1.0.1a.

- in pngtest.c (Duncan Simpson).
- Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk
- even when no tIME chunk was present in the source file.
- Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit.
- Fixed a problem in png_read_push_finish_row(), which would not skip some
- passes that it should skip, for images that are less than 3 pixels high.
- Interchanged the order of calls to png_do_swap() and png_do_shift()
- in pngwtran.c (John Cromer).
- Added #ifdef PNG_DEBUG/#endif surrounding use of PNG_DEBUG in png.h .

- Added png_get_copyright() and png_get_header_version() functions.
- Revised comments on png_set_progressive_read_fn() in libpng.txt and example.c

- Changed libpng.txt to demonstrate png_sig_cmp() instead of png_check_sig()
- which is obsolete.
