Starter Worlds (with Canvas API)

The following are starter Worlds for an absolute minimal API: Canvas. This does not use Three.js or any graphical library. It just has a canvas, on which World authors do their own 2D or WebGL rendering. This can make for a more complex World, but is needed for some authors. (Three.js or other libraries would only get in their way.) Click World image to run the World.
