Canvas is appended to body, leaves image if an error occurs.

[Luke-SF]

I noticed the script appends canvas to document.body element... Why?

document.body.appendChild(this.canvas)

If there's an error such as Uncaught SecurityError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D' it leaves the image at bottom of the page.

This issue was eventually resolved. Color Thief now does not append the <canvas> tag to the DOM: https://github.com/lokesh/color-thief/pull/150/files
