a74aa9a002 [libpng16] Replace the remaining uses of png_size_t with size_t 
In v1.6.0, size_t became a required type. It should be used
consistently. To maintain backwards compatibility, png_size_t
is still maintained in deprecated form.

  to arguments for png_get_eXIf() and png_set_eXIf().

f7d5419816 [libpng16] Avoid filter-selection heuristic sum calculations in cases where 
only one filter is a candidate for selection. This trades off code size (added
png_setup_*_row_only() functions) for speed.
