- 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).
