aa725a375c [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.

John Bowler
42369ccd85 [libpng16] Added symbol prefixing that allows all the libpng external symbols 
to be prefixed (suggested by Reuben Hawkins).  This is work in progress that
breaks some non-configure builds.

572b078d8c [libpng16] Cleaned up pngpriv.h to consistently declare all functions and data. 
Also eliminated PNG_CONST_DATA, which is apparently not needed but we
can't be sure until it is gone.

John Bowler
40ca77a721 [libpng16] Improved pngstest speed by not doing redundant tests and add const 
to the background parameter of png_image_finish_read. The --background
option is now done automagically only when required, so that commandline
option no longer exists.

it is not, or should not, be necessary.

1eb2c48458 [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.

John Bowler
8fb6c6a9b3 [libpng16] Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived) 
compiler issues slightly different warnings from those issued by the
current vesions of GCC. This eliminates those warnings by
adding/removing casts and small code rewrites.
