Hello, everyone,

It feels refreshing to NOT announce what kinds of bad things could happen
if one does NOT update libpng to the latest-and-greatest version as soon as
possible. Regardless, libpng 1.6.53 is a little better than 1.6.52, which
is a lot better than 1.6.51, which is so much better than 1.6.50, and those
of you who've been following the libpng announcements recently will know
*exactly* what I mean.

This time around we have two build fixes for two peculiar build scenarios.
First, Alexander Smorkalov fixed a misspelled intrinsic in the RISC-V RVV
code. (Spell checkers don't grok vector intrinsics, apparently.) Second,
Luis Caro Campos fixed a CMake 4.1+ build failure on Windows with Visual
C++ without MASM installed. Thank you!

For all other users who could build the previous version (1.6.52) without
any hiccup, you should be good to go with that one, and you should be just
as good to go with this one, too.
