video: Add sigmoidal upscaling to avoid ringing artifacts
This avoids issues when upscaling directly in linear light, and is the
recommended way to upscale images according to imagemagick.
The default slope of 6.5 offers a reasonable compromise between
ringing artifacts eliminated and ringing artifacts introduced by
sigmoid-upscaling. Same goes for the default center of 0.75.
