A Qt Quick GUI adaptation of Filmulator --- a film emulator with all of the
positives and none of the negatives.

Filmulator accepts raw files from cameras and simulates the development of film
as if exposed to the same light as the camera's sensor. For various reasons,
this inherently brings about several benefits:

- Large bright regions become darker, compressing the output dynamic range.
- Small bright regions make their surroundings darker, enhancing local
contrast.
- In bright regions, saturation is enhanced, helping retain color in blue
skies, brighter skin tones, and sunsets.
- In extremely saturated regions, the brightness is attenuated, helping retain
detail e.g. in flowers.

The program's design ideology is to have the best tool for any job, and only
that one tool. The tradeoff here is a slight decrease in flexibility, but
gaining a greatly simplified and streamlined user interface.
