This way, it's no longer compiled into the server.

heinrich5991 955084693d Refuse to load images of types not supported by pnglite
This allows us to think about backward compatibility while also
introducing libpng.

Jupeyy 65ad57a448 Change from pnglite to libpng for PNG reading
This is desirable mainly because libpng is maintained and pnglite is
not. pnglite was last updated in 2007 (15 years ago) and probably has a
lot of security vulnerabilities.

libpng is an actively maintained library also used by browsers like
Firefox or Chromium, so it's less likely to contain security
vulnerabilities, also it's more likely to be packaged by Linux
distributions.
