Create JSON Schema to further define and constrain the spec.

7

I would suggest creating a [JSON Schema](https://json-schema.org) to define the spec. Here's a first pass at that. ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "$id": "https://github.com/obsidianmd/jsoncanvas/canvas.json", "title": "An open file format for infinite...

Define coordinate system
