https://github.com/Automattic/node-canvas

Image/pixel manipulation in SpectralWorkbench.Image.js needs a fallback for headless usage in node.js: https://github.com/publiclab/spectral-workbench.js/blob/master/src/SpectralWorkbench.Image.js

This may include managing the image element as a JavaScript image object rather than as displayed in the DOM. All instances of imgEl and lineEl should be made optional.
