ignoreAntialiasing for typography #142

Right now Backstop is using Resemble.js for diff testing. There isn't currently a way to ignore differences in typography between WIndows / Mac. Basically, they do font-smoothing differently. Do you think it would be possible to add a diffing algorithm that detected and ignored typography rendering differences, so that Backstop could run cross-platform?

A more aggressive version of ignoreAntialiasing algorithm could help, at the risk of lost coverage. Running Backstop inside a Docker container would also help take OS rendering out of the equation.

Happy to review any Pull Requests to solve this problem.
