FYI, package maintainers:

A number of (obsolete) APIs were dropped from 1.4, meaning that a lot of
packages may not build OOTB with libpng14.  Here is a summary of the API
changes in 1.4 to guide you in porting your packages:

Do also note that the Linux distros may also have a patch for their
corresponding package, in which case you can add that to your PATCH_URI.
