  10   Replaced and extended code that was removed from png_set_filler() in 1.0.1a.
  11   Fixed a bug in png_do_filler() that made it fail to write filler bytes in
  12     the left-most pixel of each row (Kevin Bracey).
  13   Changed "static pngcharp tIME_string" to "static char tIME_string[30]"
  14     in pngtest.c (Duncan Simpson).
  15   Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk
  16     even when no tIME chunk was present in the source file.
  17   Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit.
  18   Fixed a problem in png_read_push_finish_row(), which would not skip some
  19     passes that it should skip, for images that are less than 3 pixels high.
  20   Interchanged the order of calls to png_do_swap() and png_do_shift()
  21     in pngwtran.c (John Cromer).

  36   Added "if" tests to silence complaints about unused png_ptr in png.h and png.c
  37   Changed "check_if_png" function in example.c to return true (nonzero) if PNG.
  38   Changed libpng.txt to demonstrate png_sig_cmp() instead of png_check_sig()
