Complete Lanczos algorithm

Synopsis

Declared in <boost/gil/image_processing/scaling.hpp>

template<typename ImageView>
void
scale_lanczos(
    ImageView input_view,
    ImageView output_view,
    std::ptrdiff_t a);

Description

This algorithm does full pass over resulting image and convolves pixels from original image. Do note that it might be a good idea to have a look at test output as there might be ringing artifacts. Based on wikipedia article: https://en.wikipedia.org/wiki/Lanczos_resampling with standardinzed cardinal sin (sinc)
