+Subject: [PATCH] configure: improve libpng detection
+
+Instead of looking for "libpng12" explicitly though pkg-config and then falling
+back to library hunting, just use pkg-config to find "libpng" which is provided
+by both libpng12 and libpng16.
+
+This also makes the libpng detection deterministic.
