Summary0000908: Correct colors when scaling?
Description

Does DCP-o-matic linearize / gamma correct colors when scaling?

I come to think of this when reading this thread on ffmpeg-user:
http://ffmpeg.org/pipermail/ffmpeg-user/2016-May/032199.html

Also there is some info on this in the imagemagick documentation:
http://www.imagemagick.org/Usage/resize/#techniques

Some discussion on the ImageMagick forum from 2011:
http://www.imagemagick.org/discourse-server/viewtopic.php?t=15955

Wolfgang Woehl has some notes on this to:
