image-equal

Assert that two images are similar. This is useful for testing applications with visual output, like those that work with node-canvas or WebGL. Due to platform differences, images generated by these applications are often slightly different in terms of anti-aliasing or other details, but are 'close enough' that you want to accept the result.
