98af505439 Fix MSVC Level 4 warning 
MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), but it is fine
with it if the conversion is explicitly invoked by a cast.

1df0ace0b4 Fix MSVC Level 2 warning 
MSVC doesn't like '-(unsigned)', so replace it by 0U-(unsigned) (in 1.6).

29135161d7 [libpng16] Avoid filter-selection heuristic sum calculations in cases where 
only one filter is a candidate for selection. This trades off code size (added
png_setup_*_row_only() functions) for speed.

a4b26efa1f Change image size checks 
This covers 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.)

801b925edf pngvalid.c: correct progressive read input buffer 
The previous version of the code invariably passed just one byte at a time to
libpng.  The intention was to pass a random number of bytes in the range 0..511
(and this is what happens now).
