17878c6e65 [libpng15] Work around compilers that don't support declaration of const data. 
Some compilers fault 'extern const' data declarations (because the data is
not initialized); this turns on const-ness only for compilers where
this is known to work.

c4253c4683 [libpng15] Updated CHANGES and ANNOUNCE with latest changes 2011-11-16 22:23:30 -06:00
John Bowler
4fa96a42f7 [libpng15] 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.

0a521d3785 [libpng15] 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.

a004e23a4c [libpng15] 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.

88bcdc269b [libpng] 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.

fcc0263191 [libpng15] 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. In a

1d8b75550f [libpng15] Fix for the preprocessor of the Intel C compiler. The preprocessor 
adjacent @ signs with a space; this changes the concatentation
from @@@ to PNG_JOIN; that should work with all compiler
preprocessors.

aff44028ba [libpng15] 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.
