If you're building something simple, why not just use the HTML5 Canvas API?

There's no reason to overcomplicate things, and it'll give you fine control over how things work and what you expect it to do. Layers and whatnot are pretty simple to implement a rough cut of, so why make things complicated?

Going with the native Canvas API is where I'm heading. I've used RaphaelJS in the past. This week I've tested out PaperJS and FabricJS. I'm trying to save some time and code manageability with a framework.

If you loved RaphaelJS you'll probably like Snap.svg [1] aswell. It's originally authored by Dmitry Baranovskiy (Raphael's author) and sponsored by Adobe.
