-Subject: [PATCH] Fix a regression introduced in "chore: Clean up the return
- statements"
-
-This fixes commit 27e548af2518ff8d278b45c40d11ad1bdd68eaa0.
-
-The macro `png_check_sig` has been deprecated and remained untested
-for decades. And yet, somehow it escaped from all past API cleanups.
-
-Also update the libpng manual.
