[Suggestion] Turning the canvas into an SVG

[cssinate]

I've been toying with the idea of rendering the shape output as SVG rather than a canvas element. This would make it so that each quadrant of each layer is actually in the DOM. It gives us a lot more flexibility to make this tool better in the future. We'd be able to add event listeners onto the quadrants. For example, left click on a quadrant to toggle its shape and right click on the quadrant to toggle its color. Then you could build shapes right on the canvas without having to type out the object code.

I'm happy to do the work on this, but I don't want to do it if there's no chance of it being merged.
