Changes from version 1.6.46 to version 1.6.47
---------------------------------------------
* Modified the behaviour of colorspace chunks in order to adhere
to the new precedence rules formulated in the latest draft of
the PNG Specification.
(Contributed by John Bowler)
* Fixed a latent bug in `png_write_iCCP`.
This would have been a read-beyond-end-of-malloc vulnerability,
introduced early in the libpng-1.6.0 development, yet (fortunately!)
it was inaccessible before the above-mentioned modification of the
colorspace precedence rules, due to pre-existing colorspace checks.
