**Spiegel** image filter project

- rust/webassembly for image processing
- vanilla javascript for the user interface
- no server (just static pages)

- Sorry for the poor performance, especially on larger images.
- It uses the median image filter from image.rs. That in itself can be pretty slow.
  (Although the implementation uses a _sliding window histogram_, which I think is pretty nifty).
- And on top of that, I created this custom flood fill algorithm,
  that instead of filling it with with a single color, looks up a sample from the
  Spiegel book (that has a corresponding color) and takes the pixels from that.
