2022-04-29modules/voronoi: voronoi diagram moduleVito Caputo
This adds a voronoi diagram module, which when used as an overlay produces a mosaic effect. Some settings: cells=N number of voronoi cells randomize={on,off} randomizes the cell locations every frame dirty={on,off} uses a faster sloppy/dithery-looking method Some TODO items: - use a more space efficient representation of the distance buffer, maybe use uint16_t relative offsets into the cells rather than pointers - capping their quantity to 64KiB - anti-alias edges between cells
