795662 - Update libpng to version 1.5.13

Status: RESOLVED FIXED

(Core :: Graphics: ImageLib, defect)

Description

[Ryan VanderMeulen [:RyanVM]]

Pretty minor release (we didn't update to 1.5.12 since it was only a build system update that didn't affect us):

Changes since the last public release (1.5.12):
  Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
  Removed references to png_zalloc() and png_zfree() from the manual.
  Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
    lone semicolons (patch ported from libpng-1.6.0beta11).
  Corrected handling of the image array and the row_pointers array in example.c
  When png_set_filler is used to strip a filler channel during write, the
    code prior to 1.5 would ignore the case where the output required an
    alpha channel or when the output was a palettized PNG.  In libpng-1.5 the
    ignorance was lost and libpng proceeded to strip the channel resulting
    in a bad (potential memory overwrite) failure later.  This reverts
    the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
    expected to issue an error on the erroneous png_set_filler call.
  Use png_memset() consistently (pngmem.c contained some bare "memset" calls).

Green on Try.

(Don't forget that some of this patch is updates to apng.patch, which can look confusingly like changes being made to other files)
