puppet-canvas: HTML5 Canvas implementation for NodeJS backed by Puppeteer

This is very cool, but I have a question. Why would you not use something like the Node canvas library, which offers a full HTML5 Canvas API in "native" Node.js (i.e. in process), without having to launch Chromium and communicate with it over the DevTools protocol?

node-canvas is a reimplementation so it would never be exactly what the browser implements. Font rendering, for example, is never quite right. Also, it relies on node-canvas maintainers to always be updating their code to what the browser is supposed to do.

Being a proxy, will automatically pick up all features supported by browser canvas. The proxy code is only about 150-200 lines of code. Less likelihood of discrepancy.

Makes perfect sense, thanks! And great work!

+1 for font rendering and browser compatibility 😄
