Ideas for additions:
- ~~monochrome/color switch - done~~
- decimation switch (1:1, 1:2, 1:4, 1:8) - GUI added but not functioning yet
- next/previous buttons to open next/previous image in same folder (also with left/right buttons)
- assume resolution from filesize (options are so far: 4096x3072, 4096x2160, 3840x2160)
- panning if image is larger than desktop
- zoom in (switch to next lower decimation step) with mouse wheel up and "+" button and same for zoom out with mouse wheel and "-" button
