I implemented the Lanczos algorithm in a very rough form. Here is the link
to the file: link
<https://github.com/simmplecoder/gil/blob/lanczos/test/image_processing/lanczos_scaling.cpp>
.
It needs a dependency on constants, as 3.14 might be too inaccurate with
images of much bigger resolution.  Can we bring in boost.constants (not
sure about exact name)?
I've tried to run it on a vividly colored image, and results are awesome
for my untrained eye and non-HDR monitor
(I know, means nothing).

I will start refactoring it into something more readable and versatile.

P.S. I also noticed that putting some sentences on different lines is
better to make it easier to quote.
