libpng15 breaks applications that have ignored the
fact that direct access to members of the png structures
has been deprecated for at least 12 years., since
libpng-1.0.0.

There are a lot of such legacy applications.
I they cannot be updated (author gone, etc.),
they can use libpng12 which we still support
and can coexist with libpng14 and libpng15.
