[libpng16] Corrected estimate of error in libpng png_set_rgb_to_gray API.
...
The API is extremely inaccurate for sRGB conversions because it uses an 8-bit
intermediate linear value and it does not use the sRGB transform, so it
suffers from the known instability in gamma transforms for values close
to 0 (see Poynton). The net result is that the calculation has a maximum
error of 14.99/255; 0.5/255^(1/2.2). pngstest now uses 15 for the
permitted 8-bit error. This may still not be enough because of arithmetic
error.

[libpng16] Updated configure.ac from autoupdate: added --enable-werror option.
...
Also some layout regularization and removal of introduced tab characters
(replaced with 3-character indentation). Obsolete macros identified by
autoupdate have been removed; the replacements are all in 2.59 so
the pre-req hasn't been changed. --enable-werror checks for support
for -Werror (or the given argument) in the compiler. This mimics the
gcc configure option by allowing -Werror to be turned on safely; without
the option the tests written in configure itself fail compilation because
they cause compiler warnings.
