...with the following error:
Error: main.lua:11: Drawing to the stencil buffer with a Canvas active requires either stencil=true or a custom stencil-type Canvas to be used, in setCanvas.

I was able to fix this by adding 'stencil=true' when calling love.graphics.setCanvas within chain.draw i.e.

Shall I make a PR for this?
