f9e37f54eb [libpng16] Worked around rgb-to-gray issues in libpng 1.6. The previous 
attempts to ignore the errors in the code aren't quite enough to
deal with the 'channel selection' encoding added to libpng 1.7; abort.

01a0e8062d [libpng16] Reverted addition of png_set_filler_16 and png_set_add_alpha_16() 
functions. They unnecessarily duplicate png_set_filler() and png_set_add_alpha()
which now work properly with 16-bit images.

efe4e5d10d [libpng16] Reverted the fix of byte order in png_do_read_filler() with 16-bit 
input that was made in version 1.6.17beta01, to preserve legacy
behavior even though it was incorrect.  Instead, added new API
png_set_filter_16() and png_set_add_alpha_16() that set a flag to
make png_do_read_filter() interpret the filler bytes properly.

John Bowler
2d62f7406f [libpng16] 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).

b9ba8d6a57 [libpng16] Mention in manual that 16-bit platform support has been dropped. 2015-08-16 23:32:04 -05:00
John Bowler
751cee5ef1 [libpng16] Added signed/unsigned 16-bit safety net. This removes the dubious 
0x8000 flag definitions on 16-bit systems. They aren't supported
yet the defs *probably* work, however it seems much safer to do this
and be advised if anyone, contrary to advice, is building libpng 1.6
on a 16-bit system. It also adds back various switch default clauses
for GCC; GCC errors out if they are not present (with an appropriately
high level of warnings).
