/* NL-means presets and tunes
*
* Presets adjust strength:
* ultralight - visually transparent
* light
* medium
* strong
*
* Tunes adjust settings to the specified content type:
* none
* film - most content, live action
* grain - like film but preserves luma grain
* highmotion - like film but avoids color smearing with stronger settings
* animation - cel animation such as cartoons, anime
* tape - analog tape sources such as VHS
* sprite - 1-/4-/8-/16-bit 2-dimensional games
