Update png to 1.5.7:
Changes since the last public release (1.5.6):
Added support for ARM processor (Mans Rullgard)
Fixed bug in pngvalid on early allocation failure; fixed type cast in
pngmem.c; pngvalid would attempt to call png_error() if the allocation
of a png_struct or png_info failed. This would probably have led to a
crash. The pngmem.c implementation of png_malloc() included a cast
to png_size_t which would fail on large allocations on 16-bit systems.
Fix for the preprocessor of the Intel C compiler. The preprocessor
splits adjacent @ signs with a space; this changes the concatentation
token from @-@-@ to PNG_JOIN; that should work with all compiler
preprocessors.
Paeth filter speed improvements from work by Siarhei Siamashka. This
changes the 'Paeth' reconstruction function to improve the GCC code
generation on x86. The changes are only part of the suggested ones;
just the changes that definitely improve speed and remain simple.
The changes also slightly increase the clarity of the code.
Check compression_type parameter in png_get_iCCP and remove spurious
casts. The compression_type parameter is always assigned to, so must
be non-NULL. The cast of the profile length potentially truncated the
value unnecessarily on a 16-bit int system, so the cast of the (byte)
compression type to (int) is specified by ANSI-C anyway.
Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left
the sBIT fields in the test pixel as 0, which resulted in a floating
point division by zero which was irrelevant but causes systems where
FP exceptions cause a crash. Added code to pngvalid to turn on FP
exceptions if the appropriate glibc support is there to ensure this is
tested in the future.
Added versioning to pnglibconf.h comments.
Installed more accurate linear to sRGB conversion tables. The slightly
modified tables reduce the number of 16-bit values that
convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used
to generate the tables is now in a contrib/sRGBtables sub-directory.
Added run-time detection of NEON support.
Multiple transform bug fixes plus a work-round for double gamma correction.
libpng does not support more than one transform that requires linear data
at once - if this is tried typically the results is double gamma
correction. Since the simplified APIs can need rgb to gray combined with
a compose operation it is necessary to do one of these outside the main
libpng transform code. This check-in also contains fixes to various bugs
in compose and rgb to gray (on palette).
Fixes for C++ compilation using g++ When libpng source is compiled
using g++. The compiler imposes C++ rules on the C source; thus it
is desireable to make the source work with either C or C++ rules
without throwing away useful error information. This change adds
png_voidcast to allow C semantic (void*) cases or the corresponding
C++ static_cast operation, as appropriate.
Added --noexecstack to assembler file compilation. GCC does not set
this on assembler compilation, even though it does on C compilation.
This creates security issues if assembler code is enabled; the
work-around is to set it by default in the flags for $(CCAS)
Removed "zTXt" from warning in generic chunk decompression function.
Validate time settings passed to pngset() and png_convert_to_rfc1123()
(Frank Busse).
Added MINGW support to CMakeLists.txt
Reject invalid compression flag or method when reading the iTXt chunk.
Moved pngvalid.c into contrib/libtests
Rebuilt Makefile.in, configure, etc., with autoconf-2.68
Replaced an "#if" with "#ifdef" in pngrtran.c
Revised #if PNG_DO_BC block in png.c (use #ifdef and add #else)
Revised pngconf.h to use " __declspec(restrict)" only when MSC_VER >= 1400,
as in libpng-1.5.4.
Put CRLF line endings in the owatcom project files.
Updated CMakeLists.txt to account for the relocation of pngvalid.c
Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings
reported by earlier versions.
