72855fb11e [libpng16] Made progressive reading of interlaced images consistent with the
behavior of the sequential reader and consistent with the manual. The
row_callback now receives the proper pass number and unexpanded rows,
when png_combine_row is not used or not built, by moving some code
out of the PNG_READ_INTERLACING_SUPPORTED blocks.

45625eceb4 [libpng16] Don't recognize known sRGB profiles as sRGB if they have been hacked,
but don't reject them and don't issue a copyright violation warning.
Simplified code in pngrutil.c that decides whether to warn about an
incorrect ancillary PLTE chunk.

eb657ae68f [libpng16] Added png_ptr->process_mode = PNG_READ_IDAT_MODE in
png_push_read_chunk after recognizing the IDAT chunk, which avoids an
infinite loop while reading a datastream whose first IDAT chunk is of
zero-length.

9c5a1baea5 [libpng16] Check for info_ptr == NULL early in png_read_end() so we don't need
to run all the png_handle_*() and depend on them to return if info_ptr == NULL.
This improves the performance of png_read_end(png_ptr, NULL) and makes
it more robust against future programming errors.

8f381901e3 [libpng16] Avoid up-cast warnings in pngvalid.c. On ARM the alignment
requirements of png_modifier are greater than that of png_store and as a
consequence compilation of pngvalid.c results in a warning about increased
alignment requirements because of the bare cast to (png_modifier*). The code
is safe, because the pointer is known to point to a stack allocated
png_modifier, but this change avoids the warning.

  Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
    compiled without the CHECK option it defaulted to on, not off.

  Check user callback behavior in pngunknown.c. Previous versions compiled
    if SAVE_UNKNOWN was not available but did nothing since the callback
    was never implemented.

  Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes

15a80443de [libpng16] Allow HANDLE_AS_UNKNOWN to work when other options are configured
off. Also fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
which terminates the make options (as by default in recent versions of Gentoo).

6f8f004fe1 [libpng16] Added #ifdef PNG_READ_SUPPORTED/endif around the
png_chunk_unknown_handling() function, and restored the unknown-chunk
handling code from libpng-1.6.6.
