e87d502b16 png_set_filler with 16-bit output byte swapped the value 
A simple case of assigning the low and high byte in the wrong order, may
cause problems for some apps if they already have a work-round.  The
code executes before the 16-bit byte swap so the order is always the PNG
one.

c357fb70b5 [lbipng15] Fixed the recently reported 1's complement security issue by 
replacing the value that is illegal in the PNG spec, in both signed and
  unsigned values, with 0. Illegal unsigned values (anything greater than or
  equal to  0x80000000) can still pass through, but since these are not illegal
  in ANSI-C (unlike 0x80000000 in the signed case) the checking that
  occurs later can catch them (John Bowler).

8ed373b1fa [libpng15] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the 
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.
