The advice from the png authors is that set_read_transform_info is even
more dangerous than set_read_transform_fn.

"The git head of libpng16 (and libpng17) has a fix that should allow user
transforms (but not png_set_user_transform_info) to be called after
png_read_update_info." - John Bowler

Hopefully landing in libpng-1.6.2 soon.
