John Bowler 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		2013-09-30 11:24:17 -05:00
