8ed373b1fa [libpng15] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the 
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.

bd7143e6eb [libpng15] Fixed 'unused' warnings and mergeed with libpng16 pngvalid. 
Various warnings revealed by configurations added to the tested
configurations in libpng 1.6 need corresponding fixes in libpng 1.5.
This takes the libpng 1.6 pngvalid.c and adds it back to libpng 1.5,
however one write-only test is currently disabled because it does not
work; possibly because of failures to reset or initialize the deflate
stream correctly in write-only cases.

c4c21f1c87 [libpng15] Fixed CMF optimization of non-IDAT compressed chunks, 
which was added at libpng-1.5.4.  It sometimes produced too small of a window.

0b8b358b98 [libpng15] Disabled part of the CMF optimization of non-IDAT compressed 
chunks, which was added at libpng-1.5.4.  It sometimes produces too small
of a window.  This has been fixed in libpng-1.6.0.

f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.

b2bee3374c [devel] Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is 
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
    wrong in 128 out of 65536 cases. Getting the right answer all the time
    without division is easy.
