294d0b8408 [libpng16] Detect wrong libpng versions linked to pngdeflate, which currently 
only works with libpng versions that can be made to reliably fail when
    the deflate data contains an out-of-window reference.  This means only
    1.6 and later.
  Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning
    message which it is easier to work round than ignore.

62c6fbbd29 [libpng16] Check that PNG_MAXIMUM_INFLATE_WINDOW is defined before using it. 2013-05-07 23:16:06 -05:00
John Bowler
0c7ac064d3 [libpng16] Added an option to force maximum window size for inflating. 
For inflate, reverted previous fixes.
Added fixitxt and pngdeflate to the built programs and removed warnings
from the source code and timepng that are revealed as a result.  Fixed
fixitxt when the chunk length is more than 65535 (untested, no test case).

7b1da52549 [libpng16] Ensure that NEON filter stuff is completely disabled when switched 
'off'.  Previously the ARM NEON specific files were still built if the option
was switched 'off' as opposed to being explicitly disabled.

b44cd59ad9 [libpng16] Corrected the test on user transform changes on read. It was in the 
png_set of the transform function, but that doesn't matter unless the
transform function changes the rowbuf size, and that is only valid if
transform_info is called.

43c07e1b48 [libpng16] Fixed incorrect warning of excess deflate data. End condition - the 
warning would be produced if the end of the deflate stream wasn't read
in the last row.  The warning is harmless.
