Rainbow fringes on certain scales of glasses #47

The happens on the middle of the glasses as well.

Example: kqzer9q

I'll see I can I get this in an offline environment with controlled vars for scale and background.

This will require trouble shooting. Isn't alpha blending in OpenCV really weird with blending?

I think the issue is that we're not using a real filtering algorithm, and so for the rainbow: that's the random memory you sometime get in transparent areas bleeding in because of different filtering on the alpha and the color. This could potentially be fixed by editing the original png depending on the implementation of the png loader.
