nolli

This is an experiment for me to try Bevy and play with figure-ground maps, inspired by Giambattista Nolli.

(City of London buildings from OpenStreetMap)

To try this:

1. Install Rust and Bevy dependencies
2. Get a GeoJSON file with some polygons in WGS84, using something like Overpass
3. cd nolli; cargo run --release path_to_polygons.geojson
4. Click and drag to pan, scroll to zoom, press space to start flooding from the cursor
