Libpng 1.5.23beta02 - June 2, 2015
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.

Avoid a harmless potential integer overflow in png_XYZ_from_xy() (Bug
report from Christopher Ferris).
Version 1.5.23beta02 [June 1, 2015]
Version 1.5.23beta02 [June 2, 2015]
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.
Quieted Coverity issues in pngvalid.c.
