For my GSoC project, I need a downscaling algorithm for ORB feature
detection, preferably of a good quality. Is there any in GIL already (quick
glance didn't reveal anything)? If not, I would like to implement Lanczos
resampling <>, which from
what I read is a good algorithm for scaling down. ORB also needs only
multiples of two downscaling, so I don't have any exquisite requirements.

There is a public domain implementation, imageresampler
<>. I was thinking about
incorporating it into GIL. I believe it shouldn't take too much time.

What do you think?
