sdesc: "Photographic lens distortion correction library"
ldesc: "The goal of the lensfun library is to provide a open source
database of photographic lenses and their characteristics. The lensfun library
not only provides a way to read the database and search for specific things in
it, but also provides a set of algorithms for correcting images based on
detailed knowledge of lens properties and calibration data."
