When drawing or editing an area, snap it to other areas #55
Description
When you draw an area and create a point(vertex) close to a line/vertex of another area, it should snap to that line/vertex of the other shape. This is so we don't end up with a bunch of minor buffers of 1-3 meters between areas.
The same snapping should happen when you edit the area by dragging a vertex.
The snapping should not happen when moving the entire shape, as snapping only 1 vertex to a line doesn’t add much value when the other vertex on the other end of the line isn’t parallel to the target line. (If you think it makes sense then by all means, add it 😊)
Snapping a line to another line is not something we want (perhaps not even possible?) since it would change the geometry of a shape.
Snapping is possible with the geoman.io library. https://geoman.io/docs/leaflet/options/snapping
Experiment with the snapping distance. 2m sounds like a good number in theory.
