b780eba4e4 [libpng16] Fixed cexcept.h in which GCC 5 now reports that one of the auto 
variables in the Try macro needs to be volatile to prevent value
being lost over the setjmp.

25bfb13770 [libpng16] Removed non-working progressive reader 'skip' function. This 
function has apparently never been used. It was implemented
to support back-door modification of png_struct in libpng-1.4.x
but was apparently never tested (because it does nothing and cannot
do anything).

89edbf8317 [libpng16] 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.

1088f4925f [libpng16] Fixed old cut&paste bug in the weighted filter selection code in 
pngwutil.c, introduced in libpng-0.95, March 1997.

e6877671f1 [libpng16] Backported filter selection code from libpng-1.7.0beta51, to combine 
sub_row, up_row, avg_row, and paeth_row into try_row and tst_row.

8ee821e69a [libpng16] PNG_RELEASE_BUILD replaces tests where the code depended on the build base 
type and can be defined on the command line, allowing testing in beta builds. Back
ported from libpng17.

0f12df19a1 [libpng16] Added PNG generation tool, fixed unitialized pointer in 
simpleover. Also added a comment to png.h pointing out that the pointer must
 be set to NULL!  (simpleover crashes with any slightly complex command lines
 without this fix.)

6eecfe3886 [libpng16] Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha 
value was wrong.  It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).
