Add a global setting 'misMatchPercentage' to define a KO test beyond this percentage (default is 0%).

A comparison of images may sometimes be slightly different (an offset of 1 pixel). In our case we want to identify a significant difference between two images and therefore put a test KO when the percentage difference is beyond a given threshold.

Hi thanks for the request.

from my perspective, Viff is a tool to help the guys find the difference quickly, if you set KO line for test, you also don't know if the differences is important or not.

I will hold this request for a while, I need to validate that does people want this feature. Thanks again.
