Libpng 1.4-1.5 is probably going to be a rougher transition than
1.2-1.4. As per the home page, it makes png_struct and png_info private,
which is going to break a whole lot of software that uses them directly,
and is harder to fix than the relatively minor renaming that was mostly
all that was needed for 1.4.
Waiting a year might actually be justified this time. I'd want
confirmation that at least the "important" ports (whatever that means)
build with 1.5 before committing the update.
