JSON Save Restore
We can convert a Point or PointList to JSON.
Any pointlist will cast and parse from a string:
const strPoints = points.toJSON()
`[
[250,150,10,270],
[450,520,8,270]
]`
points.fromJSON(stringPoints)
In this example, any change is written to localStorage.
Refreshing the page will restore the previous changes.
A JSON dump of stage.points exists in localStorage["polypoint-json-example"]
