Cleaned up contrib/pngminus: corrected an old typo, removed an old
workaround, and updated the CMake file.
Version 1.6.47 [TODO]
Version 1.6.47 [February 18, 2025]
Modified the behaviour of colorspace chunks in order to adhere
to the new precedence rules formulated in the latest draft of
the PNG Specification.

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.
