Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois). Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois).
Fixed the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application
as a result of the application using an increased 'row_stride'; previously
png_image_finish_read only checked for overflow on the base calculation of
components. (I.e. it checked for overflow of a 32-bit number on the total
number of pixel components in the output format, not the possibly padded row
length and not the number of bytes, which for linear formats is twice the
number of components.)
MSVC does not like '-(unsigned)', so replaced it with 0U-(unsigned)
MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), unless
the conversion is explicitly invoked by a cast.
Put the SKIP definition in the correct place. It needs to come after the
png.h include (see all the other .c files in contrib/libtests) because it
depends on PNG_LIBPNG_VER.
Removed the three compile warning options from the individual project
files into the zlib.props globals. It increases the warning level from 4
to All and adds a list of the warnings that need to be turned off. This is
semi-documentary; the intent is to tell libpng users which warnings have
been examined and judged non-fixable at present. The warning about
structure padding is fixable, but it would be a signficant change (moving
structure members around).
